Researchers have found that sad people watch significantly more television than happy people, Matt Palmquist reports on the Miller McCune blog, though it’s unclear whether sadness causes more TV watching, or more TV watching leads to sadness. The study, based on the General Society Survey conducted from 1975 to 2006, concluded that “People most vulnerable to addiction tend to be socially or personally disadvantaged, with TV becoming an opiate.” Happy people, according to Palmquist, “were more socially and religiously active, voted frequently, and read more newspapers.”
