Three Ways of Thinking Flashcards
three ways of thinking that lead to incorrect conclusions
- anecdote/experience
- intuition
- because authority figure x said so
Anecdotal evidence
personal experiences are more compelling so we over believe people
- peoples experiences are more salient to use
examples of anecdotal evidence
listening to music while studying
walking under ladders gives you bad luck
two reasons why we should reject anecdotal sources of information
- confounds
2. lack of comparison groups
confounds
human life is full of confounds
ex. you might believe that antidepressants are causing nightmares but they could’ve watched a horror movie before
comparison groups
comparison groups are important for falsification
three reasons why anecdotal evidence is problematic
- don’t include comparison groups
- tend to ignore confounding factors
- can’t be falsified
intuition
biased, it is the feeling we get that we are right
two main ways intuition leads us astray
- we love easy answers
2. we love the answer the already have
easy answers
we like easy fixes
three types of easy answers
good story
common sense
ignoring negatives
good stories
easy to believe because they make sense
common sense
easy and quick answers
common sense explanations are often contradictory
ignoring negatives
once we have an answer we have a tendency to ignore negatives
ignoring negatives:
we tend to
- over focus on confirming evidence
2. under focus on disconfirming evidence
availability heuristic
things that come easily to mind will guide our thinking
tenacity
leads us to hold onto our current beliefs
believing something simply because it has been believed for a long time
3 mechanisms of confirmation bias
cherry picking
biased questions
overconfidence
cherry picking
most people prefer information that supports whatever they want it to say
- already have access to the information that is already out there, they select from that list the things they want to believe
biased questions
happens before you have any answers
leading someone to believe what you want them to
overconfidence
a lot of people feel confident they know the answer, which leads to them not testing it and having wrong answers
credible authorities are
- expert
2. trustworthy
