Representative Bias

Can anyone explain it clearly with an example making it straight forward! (why is it called representative?)

Thank you.

you look at information presented to you - and ignore a lot of stuff, and based on your initial judgment - decide the current situation is “representative” of something else, when it really might not be so.

could happen in two ways

  1. You ignore all past information - and see the new information is representative of what you are seeing

  2. You ignore new information completely - and see the OLD information represents what you are seeing.

either way is bad…

Thank alot
