Sonja Lyubomirsky (among many others) would disagree with you (PhD, Stanford, A.B. Harvard, Summa cum laude). Check out these peer-reviewed papers for some evidence http://www.faculty.ucr.edu/~sonja/papers.html http://www.faculty.ucr.edu/~sonja/papers.html What good is living in a pessimistic world? In some cases, like finances and life-threatening situations, erring on the side of pessimism is probably the best approach (though it's definitely debatable; for example, check out the New Yorker article on cancer treatment and hospice care that was posted earlier, and please do note the results in stopping treatment inexplicably extending prognosis in cases of certain carcinomas). Anyway, the site is not designed to turn you into a cheery moron. It's designed to help you stop thinking false, incorrect, and negative thoughts, by showing you irrational distortions you're automatically invoking (out of habit). The solution, my friend, is not dogmatism - the solution is not an all-out rejection or embracement of positive psychology. Instead, the solution lies in critical thinking and honest evaluation.
