1.30.18 Lecture 2: Psychology of Questionable Belief Overview: How We Know What Isnt So Seeing order in randomness. The hidden data problem when forming our beliefs, we base them on information gathered from the world. However the world hides some information and reveals or distorts others, so hard to know our beliefs are well founded. Airline safety magazine articles knowing where exits are and rehearsing how to get to there increases chances of moving from casualty to survival. 90 of survivors mapped out plan. However, unable to interview nonsurvivors so no way to know what they were thinking. Pluralistic ignorance: most of our information about other people come from other people. People are not entirely honest, lie to themselves, etc. People tend to take social cues from society, and act accordingly; if everyone is doing this without believing in it, then everyone is just doing this without actually believing it due to the chain reaction.

Assumes that more people are for alcohol and drink regularly than actually do; adjust behavior according to the averagenorm, which may be based on false info or actions. Cant let anyone know about your own selfdoubt everyone misleads each other about their self assuredness. Imposter phenomenon achieving a level of success, but feeling out of place in that success because the surrounding peers all seem so confident and settled. Feeling like an imposter. College admission: The four quad grid, trying to figure out who did as well as expected, etc. However, no way of knowing if we short changed people who werent admitted and are still achieving because they werent admitted. Instead, only see one side of the grid see more successful admitted than unsuccessful admitted, so assume good selection process. Does adoption by infertile couples lead to better conception rates? May look like it, but no, still a 3:1 ratio. (12:4 looks more positive and true compared to 3:1.) Feature positive effect: See all of the positive examples and want to have yes positive response. Hidden data effect: The story that you want to share is about the yesyes couples, thats the advice you pass on to other people not the yesno couples. Therefore neglecting to pass on full scale of data. Pareidolia Phenomena of seeing patterns in random data the human inclination to assume that randomness does not repeat as much as it actually does. Or to see patterns where one doesnt exist.
