Question

You are discussing one of the more interesting findings from your social psychology class with your roommate. he laughs, saying that he could have predicted the finding before even hearing about it, and he makes fun of psychology for wasting time studying stuff people already know. how might you best respond to your roommate?

Answer 1

Point out that your roommate has just experienced hindsight bias or the I knew it all along phenomenon.

Hindsight bias is the tendency to believe only after learning the outcome that one would have foreseen it beforehand. In simpler terms, hindsight bias is believing that you knew something only after you heard it or that you would've known it before hearing about it.

Hope this helps!
