Could liv­ing abroad, (or more specif­i­cally, adapt­ing to a for­eign cul­ture) enhance cre­ativ­ity? Researchers con­duct­ing a series of novel and inter­est­ing tests (includ­ing the can­dle box func­tional fixed­ness test) are start­ing to sug­gest so.

Across these three stud­ies, the asso­ci­a­tion between for­eign liv­ing and cre­ativ­ity held even after con­trol­ling for per­son­al­ity vari­ables. In other words it wasn’t just that time abroad was a marker for hav­ing a cre­ative per­son­al­ity. Another con­sis­tent find­ing was that trav­el­ling abroad had no asso­ci­a­tion with cre­ativ­ity — only liv­ing abroad did. […]

The researchers cau­tioned that lon­gi­tu­di­nal research is needed to more fully test whether and how liv­ing abroad is linked with enhanced cre­ativ­ity, but they said their find­ings made a good start. “It may be that those crit­i­cal months or years of turn­ing cul­tural bewil­der­ment into con­crete under­stand­ing may instill [creativity]”.
