This is an academic exercise, as it implicitly accepts that there are natural &quot;groups&quot; in which members share the same attributes and as a result individuals within those groups can be expected to either 1) act together or 2) if apart act in a similar way as individuals. In fact there is nothing of the sort, groups are a creation of the social mind and the individual elements may or may not behave similar as individuals.<p>The brain naturally makes heuristics and clusters items that it finds similar into the same group. &quot;Stereotypes,&quot; which may be globally common traits but are attributed with higher weight to certain socially constructed groups, can memetically reinforce those groupings by making them more cognitively &quot;available.&quot;<p>There is no rational solution to this - as it&#x27;s a biological process. Like Beer, pattern matching and grouping is the cause of and solution to all of our problems.
