All traits were not created equal. -WORCHEL AND COOPER (1983, p. 180)
This book reports the findings from extensive cross-cultural studies of
the relative importance ofdifferent psychological traits in 20 countries
and the relative favorability of these traits in a subset of 10
countries. While the work is devoted primarily to professionals and
advanced students in the social sciences, the relatively nontechnical
style - ployed should make the book comprehensible to anyone with a
general grasp of the concepts and strategies ofempirical behavioral
science. The project grew out of discussions between the first author
and third author while the latter was a graduate student at Wake Forest
University, U.S.A., in 1990. The third author, a native of Chile, was
studying person-descriptive adjectives composing the stereotypes -
sociatedwiththe Chilean aboriginal minority knownas Mapuche (Saiz
&Williams, 1992). Asweexaminedthe adjectives usedinthisstudy, it was
clear that they differed in favorability and also on another dim-
sionwhichwe latertermed "psychologicalimportance," i.e., the degree to
which adjectives reflected more "central," as opposed to more "-
ripheral,"personality characteristics. More important descriptors were
those which seemed more informative or diagnostic ofwhat a person
"wasreally like"and, hence, might be ofgreater significance in und-
standing and predicting an individual's behavior.
