==About==<br />
A [[similarity cluster]] is a group of ideas which tend to be found together, or a group of things that have many characteristics in common.<br />
<br />
Because of this tendency, people tend to put labels on these groups as if they represent an unambiguous category, or to assume that the individuals involved in a cluster are in some way identical to each other, or to [[overgeneralize]] from ''some'' attributes being the same to a belief that ''all'' attributes must be the same (possibly even making negative value-judgements on individuals who do ''not'' share all the group attributes).<br />
===Attributional===<br />
In an "attributional" similarity cluster, the "similar ideas" are attributes whose values tend to be highly correlated in certain ways &ndash; leading to a "clustering" of points when the entities possessing these attributes are plotted (using as many dimensions as necessary) along the axes of those attributes &ndash; but which are not completely ''dependent'' upon each other, resulting in a small but significant population of outliers.<br />
<br />
That is: the dimensions are often erroneously conflated with each other, leading to concept-labels which assume that any given individual will be clearly classifiable as belonging to one or another of the clusters.<br />
===Examples===<br />
* [[conservatism]]: conservatism consists of a combination of related ideas, but any given type of conservatism may exclude one or more of them<br />
* [[gender]] (an attributional similarity cluster): people are not necessarily all-male or all-female<br />
* [[religion]]: religion isn't a specific thing, but a set of related ideas<br />
