The other day a friend of mine was sharing some of his recent philosophical reflections and I caught myself mentally rolling my eyes thinking that this is completely obvious. Then I thought to myself: Would I actually have thought of that myself, let alone formulated it verbally? Let's give people some slack!
A more extreme example is a post I read a long time ago about someone reading the teachings of Buddha, then shrugging them off saying "this is trivial and obvious, I could have thought of that". But could you really though? Why didn't you?
I feel that we sometimes get this kind of cognitive bias that after we hear and understand an explanation, we interpret it as easy but forget the vast difference between hearing a fact and discovering it ourselves.
My question is simply if this is a known "bias" in psychology, or if it has a name?
