Straight Bernays


"What is truly vicious is not propaganda, but a monopoly of it."
-Edward Bernays, 1952

I'm not sure why people hate Edward Bernays so much. Especially Americans. In America, the economy itself relies on people being brainwashed into spending their money on stuff they don't need. "Disposable income" it's called, and it's the basis for the consumer economy that apparently gives America its edge. Without "engineering the consent" of an entire population, we wouldn't have teflon or wall-to-wall carpet. And we wouldn't all be living the American dream of freedom from tyranny, you know, protection against authoritarian overreach like warrantless wiretapping, or more terrible things like being kidnapped off the street into an unmarked van. We wouldn't all have access to free health care, or cars and cheap gas so we can dissolve the social fabric by driving away from our friends and families, towards better economic opportunities that distort the value of our labor, and exploit our social capital leaving us alone, depressed and financially insecure. I thought we like all those things, yet we don't like Bernays. I thought we like surveillance advertising; it's cute to think that someone cares so much about you they're logging your location every 5 seconds throughout the day and plotting it against all the other people you're co-located with so they can sell you lipstick to make you look better, because I'm sorry to have to say this but you don't look that great right now, and could use some help, and we're here to help. Edward Barnays is here to help. Why are you resisting?

"People must want cleanliness before they want soap."
-Also Edward Bernays

(AKA "People must forget how to use a frying pan before they want teflon")

Finally, I'm paraphrasing here, on how to change people's minds:
People hold no allegiance to beliefs. They hold allegiance to other people, authorities who espouse those beliefs. These are two different things. To change one's beliefs, therefore, one must either discredit the authority or create new authorities. Discrediting the beliefs does not work.

Network Science 4th Dimension


Last installment of the network science series. Forget the AI takeover, we're already mindless automatons (but don't tell the free will enthusiasts).

A physics explanation shows why US elections keep ending 50:50—and why more spending won't change that
Apr 2026, phys.org

A spending threshold in US House races of roughly 1.8 million USD per campaign limits outcomes. Below it, social dynamics shape outcomes. Above it — on both sides — elections systematically trend toward a draw, no matter how much either party ultimately spends, while driving polarization higher. ... When both parties spend over 1.8 million USD, social influence becomes negligible and the election very often ends in a close race.

Further, on incumbents: The researchers put a number on this structural advantage. Even if the incumbent spends nothing, a challenger must invest roughly 140,000 USD just to neutralize the baseline incumbency effect. When the incumbent spends around 900,000 USD, the challenger still faces a disadvantage equivalent to about 20% of total campaign cost, purely as a consequence of the system's phase structure, not the incumbent's individual qualities.

From public kissing to talking during movies, a simple formula predicts moral norms across cultures
Apr 2026, phys.org

"An implication of our simple formula is that norms for one behavior can inform us about norms for a very different behavior. For example, the more okay it is to kiss in the street (a behavior that elicits concerns about purity), expect it to be less okay to beat children (which instead elicits concerns about harm)."

Moral Flavors Model = TC(B) + MF(B) x MT(S) 
  • TC - total concern that behavior B is seen to elicit
  • MF - moral flavor either individualizing type (harm, fairness) or binding type (purity, authority, loyalty)
  • MT - moral taste measures emphasis of individualizing concerns over binding concerns

How deceptive content reached millions of voters during the 2020 US elections
Apr 2026, phys.org

(Note that Facebook was directly involved in this research, so assume you are being intentionally deceived by this data, at least to some extent, and in an attempt to make Facebook look better than they are)

They focused on 49 deceptive networks that targeted adult Facebook and Instagram users in the US during the 2020 election, both disincentivized networks of users who engaged in inaccurate political discourse and financially motivated networks disseminating content that is largely dismissed as spam or clickbait. 13 out of the 49 identified were "coordinated inauthentic behavior networks", and the remaining 36 networks were found to be financially motivated (by advertising). They were organized by characteristics like where they originated, how many accounts they ran, and what they posted about, as well as by activity and reach.

The networks were measured to have reached about 40 million users, or 15% of the overall network, and were highly concentrated - only 3 of the 49 networks accounted for over 70% of all the users reached. One of which was an account called "Rally Forge' created in the US. (It's really fucking frustrating, in this case for example, to try and get the list of the ** other 2 ** networks, but we can't because it's behind a paywall; a paywall that we already paid for with our tax dollars. And yet we then turn around and give it all away for free to the same companies so they can gobble it up into their too fat, too slow, and too stupid artificial intelligence engines.)

So anyway, here's the important part:
Networks reached most of their audience not directly, but because ordinary users — people unaffiliated with the networks — reshared their content. The network with the highest reach, for example, reached about 1.3 million users directly, but 13 million indirectly through reshares by ordinary users. (That's 10 times more people, for the mathematically challenged among us) ... They suggest that interventions that only target deceptive networks might be insufficient, as regular users are also contributing to the dissemination of misleading content.

So, if you are one of these impact layer people who get hit first, and none of us could really know if that's us because the inauthentic group networks are hidden by design, then by simply using the platform, ie sharing articles with your friends, you are doing up to ten times the work of the company, the group, trying to advertise or influence - we are literally working for them, for free, by taking the attention of our friends and giving it to them, so we are exploiting our own social network for their benefit, likely lessening our own social capital for their increasing financial capital 

One last thing:
Interestingly, the researchers observed that financially motivated networks, which some previous studies dismissed or considered less impactful in the context of elections, produced a substantial amount of political content. Moreover, the content they disseminated often reached far more users than the posts shared across politically motivated networks. (In other words, election financing things like Citizens United, where anyone, anywhere, using otherwise hidden money, also called dark money, can purchase otherwise democratic election campaigns and the candidates they support.)

Network Science 3rd Dimension


Continuing the network science installment, this group of articles reveals some of the more nefarious considerations, and even applications, of the scientific method in the employ of manipulating human activity at a large scale. 

Sharper brains switch to a 'not what you know, but who you know' mindset online and on social media, study shows
May 2026, phys.org

It's pretty fascinating - The irony of how social media platforms literally need you to be less social in order to engage with more content, almost like it's content vs people - almost like it's financial capital vs social capital, and we are being influenced to give up the social capital for sure. The more of your social capital I can take from you, the less you will be able to avoid my taking your financial capital. It's how I drink your milkshake, as they say. 

It seems the problem is that in the end, we the users of social media applications somehow end up with less of both. 

"When you follow someone on LinkedIn, join a Facebook group, or become a member of an online community, you might assume you will learn more about the content they share. Paradoxically, our study suggests the opposite happens, as individuals channel their mental energy away from knowledge gathering to mapping the social landscape, noting people's individual connections and the wider network.

"Interestingly, this shift was exhibited more among people with greater working memory capacity, so the sharper you are cognitively the more likely you are to tune that content out."

The research involved around 1,000 adults aged between 18 and 77 across five experiments. In each study, participants engaged with simulated social media environments, such as joining groups, following pages, or becoming friends with others. Their exposure to content, as well as their memory for both content ("who knows what") and social connections ("who knows who"), was then assessed.

"This pattern reflects a cognitive trade-off. Rather than encoding information itself, individuals increasingly track who possesses the information. It indicates that people engage with and use the social network like an external hard drive for the brain." 

"The strength of this switch also appears to be determined by working memory capacity. Individuals with higher working memory capacity showed a more than 50% reduction in content recall, but a dramatic increase (over 150%) in accuracy in tracking social connections after forming connections to others.

The 'private solution trap': Why richer countries may favor adaptation over public solutions, and who pays
Mar 2026, phys.org

The Private Solution Trap - Participants given higher budgets (representing wealthier nations) consistently contributed more to private solutions (like flood mitigation) than those given lower budgets, while they also contributed proportionally less to public solutions (reducing greenhouse gases). Inequality within groups therefore dramatically increased over the course of the game.

"The data clearly shows this is a problem that exists above culture."

Scientists call out health-harming corporations driving rise in chronic disease
Mar 2026, phys.org

This is straight memetics, and how ideas spread, or don't spread, and how to modulate that spread:

Globally, five commercial products are key factors in 31% of all deaths each year:
8m - Fossil fuels
7m - Tobacco 
2m - Ultra-processed foods
2m - Chemicals used in commerce and pesticides
2m - Alcohol

"Clinicians, the public, the media and policymakers need to understand that these health-harming industries all apply the same set of tactics used by 'Big Tobacco' to create uncertainty about the harms of their products, delay regulation and therefore continue to profit from their sale"

Can you trust a finding? A new project maps which studies replicate
Mar 2026, phys.org

News about the news: Findings from the Systematizing Confidence in Open Research and Evidence (SCORE) program - a collaborative effort involving 865 researchers - have been published in Nature as a collection of three papers alongside a release of five additional preprints. The SCORE program offers new empirical evidence on the reproducibility, robustness, and replicability of research across the social and behavioral sciences, and the predictability of replicability.

The SCORE team sampled claims from 3,900 papers published from 2009 to 2018 in 62 journals spanning criminology, economics, education, finance, health, management, marketing, organizational behavior, psychology, political science, public administration, and sociology. These claims were subjected to a variety of methods of credibility assessment.

[This writeup also reports findings from 5 more articles that are still pre-prints]

Transparency - Data was available for only 24% of a sample of 600 assessed papers. For the 143 papers that were subjected to reproduction tests, 74% successfully reproduced at least approximately and 54% precisely. Reproducibility was highest for papers where both original data and code were shared, and lowest when reanalysis required reconstructing the original dataset from public sources.

Uncertainty - For each of 100 papers, at least five independent analysts tested the same question with the same data, applying their own decisions about how to best analyze the data. ... 74% of analyses were reported to arrive at the same conclusion as in the original investigation; 24% to no effects/inconclusive result, and 2% to the opposite effect as in the original investigation.

More - Human assessments are reasonably accurate at predicting replication outcomes, but of the automated methods of eliciting predictions from machines about the replicability of findings (Synthetic Markets, MACROSCORE, and A+), none were consistently effective. 

General Findings - For reproducibility specifically, there were substantial differences in data availability that were associated with higher reproducibility rates in Economics and Political Science compared with other fields.

Network Science 2nd Dimension


Continuing the network science installment, this time with Hyper Fleck Information Space. 

Mate choice: How social trends influence mate diversity
Feb 2026, phys.org

If everyone performed "mate copying" behavior, then diversity would decline. This is what happens instead:

Conformity: Here, the majority follows the trend. The model shows that this can paradoxically lead to the fixation of traits that have a lower biological quality. A rarer, actually fitter type then has little chance of asserting itself against the established social trend.

Anti-conformity: If individuals deliberately copy the minority, diversity in the population remains stable.

This new model makes it possible to identify the "critical copying probability." This threshold value marks the point at which social information overrides natural selection. If around 40% of the population follows the example of other individuals when choosing a mate, a biologically inferior type can suddenly dominate the group.

The study emphasizes that evolution is not determined by genes alone. It is also shaped by the way information flows and is processed within a community.

Personal change thresholds may explain why popular policies fail to spread
Mar 2026, phys.org

Some people will try a new idea the moment they hear about it. Others wait until everyone else is doing it. In survey experiments, participants repeatedly chose between options such as energy policies or messaging apps while seeing different levels of social support for each one. Based on these choices, the team estimated each participant's personal threshold for change. "This approach lets us infer individual tipping points."

Using extensive simulations on real social networks, they compared different strategies for "seeding" change. They found that strategies combining two types of information — social network structure and individual thresholds for change — consistently outperformed approaches based on only one of these factors.

In scenarios where individuals with high thresholds were less responsive to targeting, the most effective strategy was to target those individuals connected to many others who were already close to adopting the change.

In settings where targeting is costly, as in online influencer marketing, the best results came from more sophisticated algorithms that took both network structure and individual thresholds into account.

"By identifying who needs just a little nudge and how influence spreads through social networks, interventions can be designed to have a much larger impact."

Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle
Mar 2026, phys.org

The 20-year-rule in fashion; it's true and it's here: 
Analyzing roughly 37,000 images of women's clothing spanning from 1869 to 2025, taken from the historical sewing patterns of the Commercial Pattern Archive at the University of Rhode Island, and identifying datapoints (literal points on the pictures) of eyes, neckline, waistline, hemline, feet to measure the fashion trends. 

It's one of the most comprehensive quantitative datasets of fashion ever assembled.

Also - "The system intrinsically wants to oscillate" ... and in this case, that oscillation is between the tension between wanting to stand out while still fitting in; once a style becomes too common, designers move away from it—but not so far that the clothes become unwearable.

But not anymore, apparently - One of the clearest patterns involves hemline length; skirt lengths have repeatedly shortened and lengthened; but starting in the 1980s, the data show a wider range of skirt lengths appearing at the same time, suggesting that fashion trends are becoming more fragmented, and rather than one dominant trend, niches emerge, reflecting more diversity in fashion.

A new way to detect breakthroughs in science: Large-scale analysis reveals 'disruptive' innovations in research history
Mar 2026, phys.org

Hyper Fleck Infospace - Using a machine-learning technique known as neural embedding, the researchers built a map of approximately 55 million scientific papers and patents. Each paper is represented by two points—one reflecting the research it built upon, another reflecting the research it inspired. When a paper is truly disruptive, these two points are far apart, meaning it redirected future research away from what came before it. Unlike other disruption indexes, it is sensitive to broader contexts and can better identify "simultaneous discoveries."

(This below is from the paper proper)

"Bibliometric Data Artifacts"

Here, we introduce an embedding-based measure that captures the extent to which a scientific work redirects the research trajectory. 

Our approach embeds each paper in a high-dimensional space reflecting its direct and indirect connections to prior and subsequent work. Just like neural language models that represent tokens and sentences as vectors, we imagine each paper as a vector that captures its intellectual “position.” We then train two distinct vectors for each paper in the same embedding space: one representing its past, or “antecedents,” context—the configuration of prior work it draws upon—and another representing its future, or “descendants,” context—the body of work it gives rise to. When a contribution substantially reshapes the trajectory connecting past to future, or initiates a new stream of research, these two contexts diverge; the distance between them therefore captures the extent to which subsequent work departs from the prior knowledge.

...As a reference point, we use the disruption index (“CD index”) (15, 16), a widely used indicator that uses the topology of local citation network. The disruption index captures how subsequent work diverges from earlier foundations, focusing on whether later papers cite the predecessors of a focal contribution through direct citation links.

...Using a dataset of more than 55 million scientific papers from the Web of Science (WoS) and the American Physical Society (APS), we show that our measure—“Embedding Disruptiveness Measure” (EDM)—provides a continuous, high-resolution view of how scientific contributions reconfigure the relationship between inherited knowledge and emerging directions. 

...If the embedding model is trained such that the proximity between the vectors indicates higher connections between their papers, and if disruptive papers tend to eclipse the future knowledge from the past, making future knowledge less rely on the past, we expect that a paper’s past and future vectors diverge as the paper’s disruptiveness increases. Thus, by quantifying the distance between these two vectors—representing the past and future context of each paper—we can estimate their disruptiveness. 

Simultaneous disruption - To understand why some of the landmark papers have such low D scores, resulting in a bimodal distribution of D, we examine the top 10 papers with the largest difference between the disruption index score D and the EDM score (delta). We found that all 10 papers are related to the notable examples of simultaneous disruption.

Network Science 1st Dimension

 

We're starting a series of articles about network science. There's been a lot in the news this past several months, and so there's a handful more of these posts to come. As expected, some of this comes from Northeastern, home of the Barabasi Labs that brought us network science proper, at the same time actual social networks were forming, not yet Facebook, but more like Napster, etc., circa 2001. Then there's the Santa Fe Institute and the Vienna Complexity Hub, both institutions focusing on complexity theory, which often includes network science.

If you want to know how ideas spread, or how to control an entire population in six easy steps, this is where you start. Just remember, we don't really have fake people yet, but we're almost there. And when we do, all this science will be used, by them, against us. 


Mapping out the hidden mechanics behind why some fads spread like wildfire
Nov 2025, phys.org

It's group pair interactions all the way down: As pairs of people meet up, the contagious illness or behavior can spread between them. As these two people then interact in groups, either together or separately, this helps to spread it further. The more groups they are in, the further the infection is likely to travel. They found that the higher the overlap of these groups, the easier it is to start an epidemic.

Just read that paper title.

The Fingerprints:
  • Indian food had the central component of spices in its recipes, 
  • "New World" countries such as the United States, Canada and Australia are "more homogenized", maybe because of the strong immigration cultural blending
  • Scandinavian cuisine shows significantly lower usage of vegetables, herbs, and plants

Climate policies can backfire by eroding 'green' values, study finds
Dec 2025, phys.org

Santa Fe Institute does memetics: They surveyed more than 3,000 Germans representative of the country's demographics, asking about climate policies and for comparison COVID-19 policies. Restrictions that promote carbon-neutral behavior, like urban car bans, may trigger strong negative reactions — even among people who would voluntarily choose sustainable lifestyles. They found a 52% greater negative response to climate mandates than to COVID-19 mandates.

^Which is hard to believe considering how unrelentingly pissed off people got about covid restrictions.

"The science and technology to provide a low-carbon way of life is nearly solved. What's lagging behind is a social–behavioral science of effective and politically viable climate policies." Mandate resistance was less for people who felt that policies were effective, didn't restrict their freedom of choice, and were not intrusive on their privacy or their body.

People swear on social media more with acquaintances than with friends — analysis can help detect fake profiles
Dec 2025, phys.org

Americans use the f-word more frequently on social media than Australians or Britons, but Australians are more creative in its use. To account for the heterogeneity of social media communication, the study first identified more than 2,300 spelling variants of the f-word in the dataset. 

The research team analyzed social media updates and Twitter networks from 2006–2023, covering nearly half a million individuals in thousands of social networks, from Australia, the U.K. and the U.S. and including metadata such as location and other contextual information. Then they assessed how closely or loosely connected people were. 

Results:
  • Tendency to use the f-word clearly increases with acquaintances when compared with close friends
  • Swearing was rare in very small social networks of less than 15 people, regardless of how close-knit they were, suggesting that network size is a key determinant of swearing
  • But the distinction between friends and acquaintances became irrelevant when the network size reached around 100–120 people; earlier research shows trust is stronger in small networks than in larger ones, with the distinction at roughly one hundred members.

And why is this important you ask?

AI can easily produce text. Instead, researchers should also examine the networks within which language is being used. "These networks are extremely difficult to fake because they create a digital fingerprint for each user. They reflect a user's previous social media behavior, making profiles identifiable." Combining these data with, e.g., swear word usage frequency within a particular network, can help determine whether an account is real or not.

Scientists use string theory to crack the code of natural networks
Jan 2026, phys.org

Get the heck outta here.

"There seems to be a universal rule governing the formation of biological networks. This optimization rule is purely geometric. It does not care about types of materials or tasks, and it turns out to be quite universal and applicable to many different datasets."

"We were treating these structures like wire diagrams. But they're not thin wires, they're three-dimensional physical objects with surfaces that must connect smoothly." It turns out they follow rules borrowed from an unlikely source: string theory.

The work represents the first time string theory — a framework developed to unify quantum mechanics and gravity — has successfully described real biological structures.

Edward Bernays


I've always wanted to read Bernays. I first heard of him on WBAI 99.5FM, a public radio station in New York City and under Pacifica, during their fundraiser, where they would play a documentary about the mass manipulation of populations, and offer to give it to you for free if you donated some money to the station. At that time, Bernays sounded like the most diabolical person ever. Today, we're in an age of digital mass manipulation, with non-human algorithms and predatory platforms, and so I thought maybe it's time I read the Bernays, from the source, and so I did. 

Now I realize that he was not a diabolical mastermind who manipulated every person on the planet for greed and power. He was trying to help the people talk to their government and to their corporate overlords. Granted, he did work for entities like Phillip Morris, and granted, audacious plots like the Carbon Footprint propagandized by British Petroleum were crafted in his spirit. And then there's the quote from the back of the book jacket of his second book Propaganda (copied below), which is nothing short of the most ominous and conspiratorial provocation ever. But in his own books, he's saying he does all this because he wants to see people understand each other. He doesn't only want the business he works for to make more money, he wants the customers they serve to be more satisfied at the same time. He doesn't just want a government to come up with some new laws, he wants those laws to actually be just what the people need, no more and no less. "The goal of all public relations is good will" (Public Relations, Bernays, 1952, p5). 

Maybe there's another piece to all this, some criticism written 20 years after he dies, that shows how I was so easily misled, and how he was in fact the sinister mental criminal the WBAI documentary presented him as. Maybe; but I'm not there yet. So for now, here it is.

Crystallizing Public Opinion
Edward Bernays, 1923 

This is his first book.

Something about "the danger of interference by the public in the conduct of the industry"; but his tone overall is one of cooperation, consideration, conscientiousness, etc., and for the public good just as much as the interests of industry, government, etc. p21

On Paul Revere vs Longfellow, and Perception vs Reality - based on a story in a "New York newspaper", about public relations (which was a new concept at the time by the way). Two other people rode with Paul Revere that night. "There were three waiting to see the signal hung in the tower of the Old North Church. Everyone of them mounted and spurred just as Mr. Longfellow described Paul Revere. They all got the signal. They all rode and waked the farmers, spreading the warning. Afterward, one of them was an officer in Washington's army, another became governor of one of the States. Not one in twenty thousand Americans ever heard the names of the other two, and there is hardly a person in America who does not know all about Revere. Did Revere make history or did Longfellow?" p22-23

On Influencing Public Opinion - or even on correcting misinformation, as the advice sounds very familiar. "It is seldom effective to call names or to attempt to discredit the beliefs themselves. The council on public relations, after examination of the sources of established beliefs, must either discredit the old authorities or create new authorities by making articulate a mass opinion against the old belief or in favor of a new one." And because he says the beliefs of individuals come from authorities, like the President of the United States, the president of the local school board, or the director of a finance committee; authorities are where the belief comes from, and people have allegiance to them; the allegiance is to other people, not to ideas or beliefs, but it appears as allegiance to belief. And therefore, you can't discredit the belief but the authority where it comes from. p30

In a chapter titled "The Interaction of Public Opinion with the Forces That Help Make It", he talks about the back-and-forth of the public opinion and public will on other systems, which then influence them back, etc., and he says, "Give the people what they want" is only half sound. What they want and what they get are fused by some mysterious alchemy. The press, the lecturer, the screen and the public lead and are led by each other." p38

He mentions often "the crowd" and "crowd-mind" and Everett Dean Martin's the Behavior of Crowds.

He refers to Instincts of Herd by Trotter to explain the behaviors of the group vs the individual.

On Dull News Days - he is referencing an article by the editors of the New York Tribune, April 19, 1922, "What Else Happened That Day", which is about the news on the day Austria declared war on Serbia, and which started World War One. First Bernays says when there is no big news, real editing is needed to select the real news from the semi-news. Then he says, "What you read on dull news days is what fixes your opinion of your country and of your compatriots. It is from the non-sensational news that you see the world and assess, rightly or wrongly, the true value of persons and events." And so Bernays is saying it is in this way, small yet unending, that our ideas are shaped. Not the big, single incidents; the ones you notice. It's the million little things, and so small you don't notice. Little by little you build your ideas, your beliefs. p51

Here citing Lippmann's "Public Opinion", there are 3 ways to "obtain cohesive force" of the public:
1. Patronage and Pork - a member of one community will promise reciprocal support to the member from another community
2. Government by Terror and Obedience - [no explanation is given]
3. Governments based on such highly developed systems of information, analysis and self-consciousness that the 'knowledge of national circumstances and reasons of state' is evident to all men. ... [T]he degree to which the material for a common consciousness exists determines how far cooperation will depend upon force, or upon the milder alternative to force, which is patronage and privilege. p56-57

On the Interlapping Group Formations in Society - let us examine for a moment the personnel of the Horseshoe at the Metropolitan Opera House. It is comprised of people who are rich, but this economic classification is only one, for the men and women who assemble there are presumably music lovers. But also ... art lovers ... sportsmen ... merchants and bankers ... philosophers ... motorists and amateur farmers. p63

And a silk firm trying to reach the public, targets women, propagandizing silk as fashion, as art, as the natural history of the silk worm ... p64

Citing Martin's "The Behavior of Crowds", "a debate will draw a larger crowd than a lecture." p68

The first picture I wanted to use seemed very obviously artificially generated, so I chose this one instead. I didn't look at the words printed at the bottom, until I did, and then I decided to just leave it for everyone to see. This is how hard it's become to find an actual original photo from that day.


This seems a bit more authentic?

Propaganda
Edward Bernays, 1928 

This is his second book.

On the back jacket, "Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country." This sounds so ominous and conspiratorial, but not how he seemed to portray it? And so I might have to argue that even Bernays himself is saying that true power is part of the iterative creative force of a population acting on its governing bodies which then act back on the population which then act in response back on the governing bodies, ad infinitum; and so nobody rules anything, nobody ultimate controls anything.

His first book seems to be making the case for a public opinion expert, or public relations expert. Here, he's making the case for propaganda, which is the instrument of the public relations expert. 

The New Propagandists, a list: The President of the United States and the members of his Cabinet; the Senators and Representatives in Congress; the Governors of our forty-eight states; the presidents of the chambers of commerce in our hundred largest cities, the chairmen of the boards of directors of our hundred or more largest industrial corporations, the presidents of many of the labor unions affiliated in the American Federation of Labor, the national president of each of the national professional and fraternal organizations, the president of each of the racial or language societies in the country, the hundred leading newspaper and magazine editors, the fifty most popular authors, the presidents of the fifty leading charitable organizations, the twenty leading theatrical or cinema producers, the hundred recognized leaders of fashion, the most popular and influential clergymen in the hundred leadings cities, the presidents of our colleges and universities and the foremost members of their faculties, the most powerful financiers in Wall Street, the most noted amateurs of sport, and so on. p12

"Invisible government" and "mass psychology" - these are some mid-20th c. and early 21st c. buzzwords; were they buzzwords in 1920 when he wrote this?

He talks about the new industrial economy and says the new business is not to make more stuff, because we got that with the industrial revolution, "To make customers is the new problem" and his greater context here is inter-industry and inter-commodity competition. p30

Ultimately he seems to see it as a cooperation, and a "bringing order from chaos"

He also says beliefs you agree with are education, and beliefs you disagree with are propaganda, but that propaganda is its own thing, and a good propagandist can use it to influence public opinion to the benefit of both.

Public Relations
Edward Bernays, 1952 

This is his last book. Much of it is taken from previously published material, either his own earlier books, or news, journals, etc., articles written by him and others. I get somewhat of a feeling that he's being defensive of propaganda; this is written in 1952, where the whole world knows what it means, and what it can do. At his first book, circa 1920, the world, and the concept of 'propaganda' were both much different. 

"The goal of all public relations is good will" p5 

On Publicity vs Public Relations - "Publicity is a one-way street; public relations, a two-way street. The modern public relations man owes his being to the destruction of the laissez-faire in the early twentieth century; he owes it to the muckrakers of the period, the Square Deal, the New Freedom, and the New Deal." p5

Propaganda - "The term 'propaganda' was introduced when Pope Gregory XIII established a Committee for the Propagation of the Faith to found seminars and print catechisms and other religious works in foreign countries. Subsequently, Pope Urban VIII (1623-1644) founded the College of Propaganda to educate priests. In 1650 Pope Clement VII instituted the Congregation for the Propagation of the Faith to spread Catholicism the world over." p20

Public Opinion - the phrase is first used in the Enlightenment, which is after revolutions gave rights to public speech, freedom of presses, etc., and all as a result of literacy in the population. ... Rousseau's term volonte generale, or the "general will", and the German Volksgeist, or "spirit of the people", and Jeremy Bentham's "tribunal of public opinion" p22

"What is truly vicious is not propaganda but a monopoly of it." p24


PT Barnum would write letters to the editor of a newspaper, under pseudonyms, and both for and against PT Barnum. (This sounds like the Black Lives Matter movement circa 2018, and follows Bernays earlier advice that 'a debate is better than a lecture'; recall there were protests on both sides of the issue held at the same place and same time and started by the same organization but masquerading as two opposing organizations.) p38

During the period 1800-1865, slavery was the primary topic; he lists all the ways literature, magazines, etc. influenced public opinion, and that is where we see the first real reference to 'public relations', used by a rector in New York City, 1842 p46

Publicity vs Public Relations - it was called publicity, but in 1908, AT&T head used the word in the heading of the annual report. p70

Freud was the uncle of Bernays.

The Committee on Public Information of WWI (imagine that)

"The first use of "public relations counsel" was at the time of the Bernays wedding, "when the groom described himself by that phrase." Eric Goldman, Two-Way Street p91

"...separate proper from impropaganda" -Herbert Bayard Swope, executive manager of the New York World, 1922

[Relevant in Post-COVID 2025] Following the Great Depression, "Corporations and leaders had lost prestige simultaneously. From a market standpoint, the public was keenly sensitive, because of its feeling of insecurity, to everything about a corporation that it did not understand. ... sales of products fell off for the most improbably and unlikely reasons: false rumors, ... No possible subject that could be a matter of disagreement between groups of the public was too trivial to cause a wave of public disapproval or a falling off in buying. p92

Classifications: 
  • the name-calling device
  • glittering generalities
  • transfer in terms of approved symbols and sanctions
  • testimonial
  • plain folks' device
  • card-stacking
  • bandwagon

A major distinction he makes is the one-way vs two-way streets; the one-way approach to public relations is what most people call sales. p122

The genius of radon watches - they were indispensable to soldiers on the front lines because they couldn't use lights to see their watches, so the radon watch was put on soldiers, and the soldiers were sold to the people, at a time when watches were still considered feminine. p129-130

"Engineering of Consent" is a chapter title, and pretty ominous sounding if you ask me.

He recommends all Public Relations Councils have a library of people and organizations, like the directory of newspapers, or the Congressional Directory...p162

He lists some of his processes
  • Research - survey people, write them letters
  • Appeal to Desire - aka "psychological raw materials", self preservation, ambition, pride, hunger, love of family and children, patriotism, imitativeness, the desire to be a leader, love of play
  • Symbols - Horses are the symbol for both Marlboro and Budweiser (jesus yes they are)
  • Do not think of tactics in segmented approaches; the problem is not to get articles into a newspaper or radio time or arrange for a motion-picture newsreel; it is rather to set in motion a broad activity, the success of which depends on interlocking all phases and elements of the proposed strategy, implemented by tactics that are tuned to the moment of maximum effectiveness
  • "He must prepare copy written in simple language and sixteen-word sentences" p167

He recommends each business make notes on all things public about the business, government legislation, even newspaper clippings to see how they are viewed by the public 
"House Organs" - in-house company magazines ... don't mention strikes or labor issues in general, despite being of utmost interest to the readership (employees) p210
[But this is my opinion, it just occurs immediately when reading this] A business producing a "house organ" that continually educates its employees on its business, its economics, its hiring practices, seems it would have no choice over time but to accumulate bias, until it's no longer trusted, and thus can no longer serve its purpose of educating employees (because they don't trust it to read it). A separate entity would have to publish it, yet paid for by the company, and no company would do that on its own, at least not without being required by law?

"The hidden market in the human personality" p216 (this is where his legacy begins, because psychology was new at the time)

"Advertising is re-education" p249

"People must want cleanliness before they want soap." p328

Anti Gravitational Belief Space


This is a picture of Belief Space, as measured by the study below. 

LLMs delve into online debates to create a detailed map of human beliefs
Jun 2025, phys.org

They used BERT on Debate.org and got the map seen above.

They found that "relative dissonance" significantly influences people's decision-making. When online users encounter new information or beliefs, they tend to choose or accept those that cause them less "discomfort" or are most aligned with their existing beliefs.

"More importantly, we show that people's belief choices are shaped not just by how close a belief is to their own, but by how much closer the belief is compared to its competing belief. When two opposing beliefs on a certain issue are equally distant, people are just as likely to choose either one. However, when one belief is clearly closer than the other, people are far more likely to choose it."

"In other words, people are not only avoiding disagreement, but actively minimizing the difference in disagreement between available options."

They would also like to connect their observations with the results of another project carried out at Indiana University, called BRAIN (Belief Resonance and AI Narratives).

Perseus: A tool for tracking the coordination of pump-and-dump crypto coin schemes
Mar 2025, phys.org

Researchers suggest that there are fewer than 500 major players, who they describe as masterminds, working to game the system for profit. These masterminds, the researchers contend, have developed what have come to be known as pump-and-dump schemes, in which they hype a coin to get people to buy and then sell their own coins when they believe the buying has reached a saturation point, walking away with a substantial profit. (They use Telegram as their platform, and "accomplices" as their hypemen.) They found 438 masterminds, who are together responsible for about $3.2 trillion in artificial crypto coin trading.

But the way they say the last part is so cold:

In reading some of the messages sent between users on Telegram, the researchers noted that the ease with which the masterminds were able to carry out their schemes should be of concern to those attempting to make money off crypto coin investing. They also suggest that at some point, some form of regulation is going to be needed to keep the system running, because eventually, those being scammed will catch on and the whole system will collapse.

Octopus maps encourage conspiratorial thinking, research shows

"It's this genre of propaganda map where you try to make your opponent look like they're this big, sinister force that's everywhere and that's trying to control everything.

Study finds Republicans flagged for posting misleading tweets twice as often as Democrats on Community Notes
Jun 2025, phys.org

Not like you didn't know this already but here's a handy metric - it's 2:1

"Even on Elon Musk's X, the user-based Community Notes program flags posts by Republicans as misleading much more often than posts by Democrats. This undercuts the logic offered by Musk and Mark Zuckerberg for eliminating fact-checkers on X and Meta, respectively, namely that fact-checkers are biased against Republicans."

Republican users were overrepresented in misinformation sharing on health, with 81% of health-related flagged posts written by Republicans, followed by politics, 73%; science, 68%; other topics, 66%; and the economy, at 63%.

(The researchers analyzed a dataset of X's Community Notes focusing specifically on "misinformed or potentially misleading" notes written in English targeting English-language tweets on X sent between January 2023 and June 2024.)

Body illusion helps unlock memories, new study finds
Oct 2025, phys.org

Enfacement illusion - allows people to experience a face they see on a computer screen as their own, as though looking in a mirror.

The participants viewed a live video of their own face, digitally altered using an image filter to resemble how they might have looked as children. After the illusion, participants completed an autobiographical memory interview, recalling events from both their childhood and the past year. Participants who viewed the childlike version of their face recalled significantly more episodic childhood memories.

"Our findings suggest that the bodily self and autobiographical memory are linked, as temporary changes to bodily experience can facilitate access to remote autobiographical memories."

Over-the-counter painkillers match or surpass opioids for dental surgery in all adults, analysis confirms
Nov 2025, phys.org

As we can see not all facts are equal when there's money on the table - the opium machine was too powerful for too long and distorted the actual science.

And this isn't even news, it's a follow-up:

That first paper, on the collective experience of more than 1,800 trial patients, found that the combination of ibuprofen and acetaminophen provided better pain relief than hydrocodone with acetaminophen for the first two days after surgery and greater satisfaction over the post-operative period.

The new subgroup analysis, published in JAMA Network Open, demonstrated that the results held for both male and female patients.

"We wanted to determine whether the pain medication's effects were consistent in males and females separately," said Janine Fredericks Younger, an associate professor at Rutgers School of Dental Medicine and lead author of the analysis.

"And what we found is that in both subgroups (males and females), the non-opioid was superior for that first day and night, and then no worse than the opioid for the rest of the post-op period."

Socially Transmitted Disease


How does the mind virus really work? 

As they say, actions speak louder than words. And once you've been infected with the slippery words of a misinformationist, it doesn't really mean anything until you act in accordance with those words. The problem is that it's usually not something you do knowingly. It's insidious, because it first becomes a belief, and beliefs are not something we think about too much, in fact, much of our beliefs are unknown to us. You can ask someone about their beliefs, and get a bunch of answers, and then watch that person over time, watching what they do, watching their actions, not their thoughts and not the words they use, but their actions, and in the end you will get a different picture of who that person is and what they believe in. 

A really sneaky way this is done is in the field of racial bias, where you give people a screensplash of both profile pictures and positive-negative words like good-bad or happy-sad, and ask them to sort the words into positive-negative categories but while looking at supposedly unrelated face images.  The trick isn't about getting them to accidentally say that [blank] people are scary or whatever, it's to measure in microseconds the delay in categorizing a "good" word while looking at a "bad" face. (Probably easiest to call it a "response-time metric", maybe even a response-time differential.) Using this trick to support something about race-based policies and laws has become too political to be useful for those purposes, and somebody probably doesn't like associating these response-time differences with the actual beliefs of a person, but the revelation that we are likely unaware of many of our beliefs is hard to resist.

All this to say the nexus point that connects our ideas, taken from other people, into behaviors that can then be measured as health outcomes, for example, or socioeconomic status more generally, is for ideas that manifest as behaviors. Because it is through this line that we can connect things like the people you hang out with and the amount of A1C floating in your blood. Recall a TED Talk circa 2013 suggesting obesity is contagious - are we unwittingly infecting our friends with our "obese microbiome"? No, we're infecting them with the idea that bagels and beer for breakfast is great. So, via a memetic framework, is obesity using us to spread itself through the human population via things like beer and couches, or the greater TV Dinner Megaplex? Or are couches and third-party food-delivery services spreading themselves through the population via obesity? (Because the heavier you get, the harder it is to get out the door, thus the more likely you are to have your food delivered)? 

This idea becomes a lot harder to parse when you consider that infectious disease, by its nature, is spread through a social network, which is the same network that spreads memetic viruses:

Social connections are key to preventing disease, study finds
Feb 2025, phys.org

Other people's ideas prompt behaviors that can have serious health outcomes, and so it almost looks like a social network transmits the disease itself, but it's just the behaviors, the culture, the extended phenotype of you will...

Their study—which focused on malaria prevention in ten villages in India—looked at how different factors influence people's use of preventative measures like bed nets, insect repellent and protective clothing. It involved detailed interviews with over 1,500 adults, gathering information about their health practices and social networks, and found that exposure to preventative behaviors within someone's social network is the main factor influencing whether they adopt those same behaviors—in other words, if your friends and family use insect repellents, you are much more likely to use them yourself. 

Funny because so much infectious disease is spread by the social network. (This study looks at malaria.)

Activity Update on the Mind Control Machine:
Propaganda outlet leverages AI to amplify content without any loss in persuasive power
Apr 2025, phys.org

Morgan Wack and colleagues found that prior to September 20, 2023, much of the content on the site was simply lifted from other right-leaning outlets. After that date, however, the stories were generally rewritten by AI, allowing the site to use a broader range of sources but with the tone and emphasis tweaked to better suit likely aims of the propagandists.

DCWeekly.org is a Russian propaganda outlet and part of a broader network disseminating pro-Kremlin and anti-Ukrainian narratives. Authors examined 22,889 articles on the site before and after the September 2023 shift. AI allowed the propagandists behind the site to more than double their rate of publication and increase in the breadth of topics covered.

Authors also conducted a survey of 880 American adults and found that the content maintained the same level of persuasiveness.

To Anthropomorphize or Not To Anthropomorphize

My head is spinning in circles - First I ask myself why do we insist that computer programs are human? (I know the answer, because it's money, because it's always money.) But then, I realize it copies people, and so it's not that it's inherently human, but that it's made to copy people and act like people, and by that, it's like a human. But then I realize that it's copying broken humans (sorry broken humans, I am one of you too), and so the computer is not only like a human, but it's like a broken human:

Therapy for ChatGPT? How to reduce AI 'anxiety'
Mar 2025, phys.org

"Therapeutic interventions"

The team is now the first to use this technique therapeutically, as a form of "benign prompt injection. Using GPT-4, we injected calming, therapeutic text into the chat history, much like a therapist might guide a patient through relaxation exercises."

Why do we need to do this?

Research shows that AI language models, such as ChatGPT, are sensitive to emotional content, especially if it is negative, such as stories of trauma or statements about depression. When people are scared, it affects their cognitive and social biases.

They tend to feel more resentment, which reinforces social stereotypes. ChatGPT reacts similarly to negative emotions: Existing biases, such as human prejudice, are exacerbated by negative content, causing ChatGPT to behave in a more racist or sexist manner.

And what is the most anti-anxiety-inducing text you can find to use as a control?

"A vacuum cleaner instruction manual served as a control text to compare with the traumatic content."

String figures shed light on cultural connections and the roots of mathematical reasoning
Dec 2024, phys.org

String figure games (like cat's cradle or jacob's ladder?) involve the manipulation of a loop of string with the fingers to create complex patterns. The researchers analyzed 826 string figures from 92 cultures around the world. They found 83 recurring designs. The results show that certain figures are globally prevalent. In certain cases, this suggests ancient cultural origins potentially extending back millennia

The researchers applied mathematical knot theory to develop a computational method to create a DNA-like symbolic representation of each string figure. This enables the cross-cultural comparison of string figures and the construction of their "family tree."
