Stereotypes are actually surprisingly effective. Their main problem is we have too few (?). "Studying cultures is about acquiring many useful stereotypes"
"That’s why small talk about last night’s episode of Game of Thrones isn’t a waste of time. It communicates: I am like you, you can model me well by looking at yourself, we can cooperate."
On creepiness: "The perception of creepiness is a
response to the ambiguity of threat. […] While they may not be overtly
threatening, individuals who display unusual patterns of nonverbal
behavior, odd emotional responses or highly distinctive physical
characteristics are outside the norm, and by definition unpredictable."
Read [[The Intelligent Social Web]]. Seems relevant to multiple identities and conflicts arising from those (e.g. what happens when one goes back to old friends/family).
On big shifts to beliefs not supported by a scaffolding of smaller beliefs: "Without this scaffolding, adopting the new idea will promptly make the
world less predictable even if it may be a better-predicting model in
the long term. This feels bad, and your brain will pull out all the
stops to avoid it: confirmation bias, isolated demands for rigor, flat out denial."
[[Entropic Brain Hypothesis]]: Our brains evolved to model the environment and minimize surprise and
uncertainty. Since our environment is complex and dynamic, so are more
evolved brains. fMRI allows us to measure brain entropy, how
unpredictable is one’s brain state in the future based on its current
state. It’s a proxy for a brain’s flexibility and complexity.
It is easy to fixate on the "markings" for an identity instead of its "core": "adopting X as an identity makes you optimize for being predicted as X, rather than for X itself.
If you tell people about the book you’re writing they’ll predict that
you’re a writer and will treat you accordingly, reinforcing your
identity. If you merely accumulate words in a draft file, they won’t.".
