Andy Luttrell, a psychological science professor, pens a column for Psychology Today. In the column, he explains how to get people to care about economic inequality.

You might be surprised to find that some of people's strongest opinions are held without many strong arguments in support of them -- a phenomenon that is likely true for you, too.

According to Ball State University professor Richard Petts: “The reluctance—or inability—of men to take child-care leave is often considered harmful to women, who miss opportunities for promotion when they are out of the workforce for longer periods than men. When men take longer leave, two things happen: women return to work sooner, and men become more attuned to, and less tolerant of, those opportunity costs. What’s more, dads who take longer leave also tend be more involved in their child’s life and care overall.”

A recent study from Ball State University indicates that people in their 70s who have exercised regularly for decades have heart and lung capacity like healthy people in their early 40s, and you don’t have to be a competitive athlete to reap most of those benefits.
