Just that it's _typically_ a source of errors ... because most people
don't have very complete mental models, and (often unknowingly) rely
on symmetry to fill in gaps.  To the extent they may not even be aware
such gaps exist.

It's better to have such basic cognitive mechanisms working in your
favor (by preferring symmetric designs, vocabulary, framing) then
against (asymmetric, ditto).
