Attack politics costs us dearly in terms of insight into the candidates. In a presidential campaign, the focus is so tight that the politicians are afraid to say anything that hasn't been scripted.

Unsurprisingly, the poll-takers don't talk a lot in public about the ignorance of the electorate on political and public policy matters. And the politicians are not going to disclose the, let's say, limited body of knowledge in their constituencies. You don't get elected calling your voters airheads.

Pictures can be devastating. Who allowed John Kerry to get himself photographed windsurfing in a flowered swimsuit? Anyone in the real world in that operation?

I have always argued that newspapers should not have any civic purpose beyond telling readers what is happening... A reporter who doesn't quickly tell readers what they most want to know - the score - won't last long. Better he should teach political science.

There is no common standard for education about diagnosis. Distinguishing between bipolar depression and major depressive disorder, for example, can be difficult, and mistakes are common. Misdiagnosis can be lethal. Medications that work well for some forms of depression induce agitation in others.

People have come to me for my opinion since 'October Baby.'

I'm not talking about politics. I'm just trying to have a conversation with my own kids.
