A new study shows that wisdom and ability to resolve conflicts could be the result of the social culture.
Americans are known to emphasise individuality and solve conflict in a direct manner. Conversely, the Japanese place a greater emphasis on social cohesion, and tend to settle conflict indirectly, relying on mediation through another person.
Psychological scientist Igor Grossmann of the University of Waterloo, Canada and his colleagues investigated how the resolution of conflict and, by extension, wisdom, differs between Japanese and American cultures, the journal "Psychological Science" reports.
Next, they read stories about conflict between individuals - including siblings, friends, and spouses - and answered the same questions. As Grossmann and colleagues predicted, young and middle-aged Japanese participants showed higher wisdom scores than same-aged Americans for conflicts between groups, according to a Waterloo statement.
For conflicts between people, older Japanese still scored higher than older Americans, though this cultural difference was much smaller than the difference observed between the younger adults.
Interestingly, while older age was associated with higher wisdom scores for the American participants, there was no such relationship for the Japanese participants.
These findings underscore the point that culture continues to be important for human development, even into old age.
While wisdom may come with winter for Americans, the same may not be true for other cultures.
