Scholars seeking to understand the causes and consequences of
political intolerance are now celebrating the fifty-year anniversary of
Stouffer's pathbreaking research on intolerance and repression. Yet
despite substantial advances in our understanding of intolerance, several
major unanswered questions remain. The purpose of this article is to
identify and discuss these tolerance enigmas, while proffering some ideas
about how future research on intolerance might proceed. The article begins
by documenting the significance of understanding intolerance and concludes
with speculation about how resolving these enigmas might contribute to a
more peaceful and democratic world.James L.
