Don't fall behind. Prosper from Kiplinger's most valuable guidance of 2009, as measured by the number of your fellow readers already benefiting from it all. By The Kiplinger Washington Editors December 1, 2009 As Kiplinger’s Personal Finance senior editor Bob Frick explains in the Be a Better Investor article that kicked off our series on investor psychology, “herd behavior” often makes us think something is safer than it really is because everyone else is doing it.
