From Barry: According to an article in U.S. News & World Report, a recent study published in Psycho­log­ical Science found that those with more opti­mistic atti­tudes had better-func­tioning immune systems which, in turn, helped them ward off illnesses. Might the same be true of orga­ni­za­tions? According to the story, far too many of us assume that opti­mism is an inborn trait bestowed on a lucky few. That’s a completely wrong assump­tion, says James Maddux, a professor of psychology at George Mason Univer­sity. Can people (and by impli­ca­tion orga­ni­za­tions) learn to be opti­mists? “The answer is an indis­putable yes,” says Maddux. · Go to How to keep your orga­ni­za­tion opti­mistic →
