• EDGE -- JAN. 4
When scientists and other prominent intellectuals change their mind about important things, their new outlook often is gloomier. That, at least, is the theme of responses to a survey conducted by online science-and-culture publication the Edge, which asked some influential thinkers: "What have you changed your mind about? Why?"

In 2002, a study showed him that people are more satisfied with irrevocable decisions than with ones they can reverse. Acting on the data, he proposed to his now-wife. "It turned out that the data were right: I love my wife more than I loved my girlfriend."
