The DSM-IV is the manual used by psychiatrists to diagnose mental illnesses and, with each new edition, there are scores of new mental illnesses. Are we becoming sicker? Is it getting harder to be mentally healthy? Authors of the DSM-IV say that it’s because they’re better able to identify these illnesses today. Critics charge that it’s because they have too much time on their hands.
New mental illnesses identified by the DSM-IV include arrogance, narcissism, in above-average creativity, cynicism, and antisocial behavior. In the past, these were called “personality traits,” but now they’re diseases.
