“Our heads are round so that our thoughts can change direction.”
— Francis Picabia
Mere exposure effect: Psychologist Robert Zajonc found that people can be persuaded to have positive inferences about an object (brand, party, candidate, etc.) through increased exposure. Controlling for aesthetics and other source material and content characteristics, Zajonc found that increasing exposure leads to higher favourable attitudes–in effect, a “familiarity breeds contentment” route to persuasion that doesn’t require any real substance to the content (via Thick Culture).
Change blindness: The term “change blindness” refers to the fact that people must choose what to pay attention to in any given setting. Accordingly, when the details they’ve decided aren’t important change, they don’t notice. In an experiment by psychologist Daniel Simons, an assistant behind a counter, pretending to sign students in for an experiment, is surreptitiously replaced by another person. A full three-quarters of the people don’t notice (via Sociological Images; follow the link for videos of test subjects demonstrating change blindness).
Fundamental attribution error: the idea that each of us as an individual is biased toward viewing our behaviors within the context of our circumstances. However, when we view the behaviors of others we attribute their behaviors to who they are as a person or to their character. (via Sociology Source)
Confirmation bias: the bias we have toward accepting information that confirms our worldview without critique while at the same time being overly critical of information that counters are preconceived notions of the world. (via Sociology Source)
