Based on two longstanding national surveys of high school seniors and college freshmen, [San Diego State University's Jean] Twenge and her colleagues found a decline, over the last four decades, in young people's trust in others, their interest in government and the time they said they spent thinking about social problems.
Steepest of all was a steady decline in concern about the environment, and taking personal action to save it.
Researchers found that, when surveyed decades ago, about a third of young baby boomers said it was important to become personally involved in programs to clean up the environment. In comparison, only about a quarter of young Gen Xers - and 21 percent of Millennials - said the same.
Meanwhile, 15 percent of Millennials said they had made no effort to help the environment, compared with 8 percent of young Gen Xers and 5 percent of young baby boomers.
