o see emotional issues finally\rtaken seriously, they fear that a notion as handy as EQ invites misuse.\r"People have a variety of emotion," argues Harvard psychology professor Jerome Kagan.\r"Some people handle anger well but can't handle fear.\rSome people can't take joy.\rSo each emotion has to be viewed differently."\rEQ is not the opposite of IQ.\rSome people are blessed with a lot of both, but some with little of either.\rWhat researchers have been trying to understand is how they work together; how one's\rability to handle stress, for instance, affects the ability to concentrate and put intelligence\rto use.\rAmong the ingredients for success, researchers now generally agree that IQ counts for\rabout 20%; the rest depends on everything from social class to luck.
