# Bosons and the Pauli Exclusion Principle

## Main Question or Discussion Point

Do bosons tend not to obey Pauli Exclusion Principle?
I would appreciate if someone would send me some material about this question, and answer it as well.

Bosons do not obey the exclusion principle. Only fermions do.

Boson wave functions must by completely symmetric, so there is no 'exclusion', but some states are still ruled out.

A good exercise is to consider a bound state of two fermions forming a boson. Then try to find the solution to the following paradox. While the bosons can be in the same state, the fermions they consist of can't. How is this possible?
