It's all about the details.
Politics may follow you on the road, bumper sticker study finds
Oct 2025, phys.org
Just here to point out that "I love my dog" is the epitome of politically neutral bumper sticker:
They conducted attitude surveys with paid volunteers ... The offending vehicle featured either no sticker or one of three bumper stickers: "Proud Democrat," "Proud Republican" or the neutral "I love my dog." Drivers were far more likely to honk after being cut off by a vehicle bearing a political bumper sticker, particularly one for the opposing political party.

Hand gestures that illustrate speech boost persuasiveness, study shows
Nov 2025, phys.org
I just like how they used 2000 TED talks as the dataset:
They analyzed 2,184 TED Talks using AI and automated video analysis, isolating more than 200,000 hand gestures into 10-second clips and comparing them against audience engagement metrics such as "likes" on social media, while controlling for factors like gender, occupation, language, video length and more; and they ran randomized experiments in which participants watched videos of sales pitches where speakers delivered identical scripts but varied their hand movements. Viewers then rated the speakers and the products being pitched. ... "Illustrators" might demonstrate the size of a fish while describing it, and "highlighters" might point to an object mentioned (like pointing at a word on the chalkboard?). ... "When people use illustrators, it increases viewers' perception of the speaker's competence. If a person uses their hands to visually illustrate what they're talking about, the audience perceives that this person has more knowledge and can make things easier to understand."
