Figure 5 Relative dominance of rule-based versus family resemblance-based judgments of categories for the same cognitive task. European-American, Asian-American, and East Asian university students were tested by Norenzayan et al, 2002; the herders, fishermen, and farmers of Turkey’s Black Sea coast were tested by Uskul et al, 2008. Positive scores indicate a relative bias towards rule-based judgments, whereas negative scores indicate a relative bias towards family-resemblance based judgments. It can be seen that European American students show the most pronounced bias towards rule-based judgments, and are outliers in terms of absolute deviation from zero.
