I don’t see how this study does any good unless first they measure the rate at which people actually match the stereotypical preconceptions and then compare this with the two average ratings. Otherwise it is possible the people were becoming less biased, not more.
Data already suggests from a number of studies that people over-estimate how much information they can glean from stereotypes. See for example the studies involving names and resumes.
