A legitimate experiment to try: write down the names of the ppl
who fit the profile of the MRA. Notice if the same names come up
in conversations. Add any new names you find. The actual pool
size might be very tiny but with noisy voices. It proves over
representation of a tiny group. Once there is a group
established (a stereotype filled with identities rather than
impressions) - it can be further dismantled by seeing the
members as individuals.
