An inner amenable group is one in which there is a finitely additive conjugation-invariant probability measure on the non-identity elements.  In this talk, we show that inner amenability is not preserved under elementary equivalence.  As a result, we give the first example of a group that is inner amenable but not uniformly inner amenable.
