What you difference between over attribution and fundamental attribution error?
I think that overattribution is when one's obvious
characteristics(e.g. being rich) is singled out and is made reason
to almost anything he/she does. Fundamental attribution error is
using what you've known primarily of the person(e.g. being
inconsiderate) and deducing that the person did what he/she did
because of the kind of person he/she is.
