If ideas serve a role in sexual selection, then an opposing ideas espoused by
a potential rival is obviously more of a threat than one that is not. Hence
we may have more motive to find errors in an argumentative setting than
otherwise, even with a sham rivalry.
Not a theory, but a starting hypothesis.
