Philosophy Final Part 1 Flashcards
System 1
feels automatic and effortless
can’t be turned off
source of impressions, feelings, intuitions and emotions
System 2
voluntarily controlled
chosen
associated with dilated pupils and accelerated heart rate
come with feeling of effort
System 1 and 2 conflict
system 2 has to override system 1’s automatic reactions, but wrong impression doesn’t always go away
i.e. when you know the lines are the same length, but one looks longer than the other
cognitive illusions
system 2 has to override initial reaction of system 1
confabulation
system 2 creates reasonable-seeming explanations for unreasonable inclinations generated by system 1
cognitive laziness
system 1 suggests an initial conclusion, system 2 may come up with a solution but you are already satisfied
rationality
being lazy and not using system 2 is a matter of rationality
intelligence
something measured, IQ test, but doesn’t determine how prone you are to biases
anchor-and-adjust heuristic
when making a judgement or estimate along a scale, we unknowingly use a reference point suggested to us as a mental anchor
implicit association tests
measure levels of cognitive difficulty when performing tasks with category
base rates
chance of a random person being a certain thing
heuristic
a cognitive shortcut used to bypass a more effortful type of reasoning
anecdotal reasoning
small samples are inherently weak as evidence, observations are not random samples
selection effects
when our overall impression is biased because the cases we observe have been selected by a process that filters them out
availability cascades
when the media’s focus on a topic and the emotional reaction of the public to that topic feed on each other, resulting in a cycle of escalating intensity
echo chambers
when our sources of information and commentary have all been selected to support our opinions and preferences
survivorship bias
i.e. knowing a lot of people who smoke and thinking smoking is safe, forgetting that many who smoked have died
publication bias & file drawer effect
not everything is published, researchers file away results they aren’t interested in
familiarity effects
the subconscious inclination to think something is true just because you are familiar with it
salient hypothesis bias
when observations that support a hypothesis bring it to mind, but observations that disconfirm it do not bring it to mind
explanation freeze
when one seeks to explain something and only a small number of explanations come to mind, resulting in an overestimate of the probability of those explanations
law of large numbers
as we increase our sample size, we get closer to the true population values
cognitive ease/familiarity
assuming that if an answer is familiar, it must be true
evidence for the familiarity effect
people prefer how they look in the mirror to pictures
seeing a company’s name induces us to find it more familiar and positive
