The problems of getting involved in public debate

From Greg Mankiw's blog:

Mankiw Says Higher Taxes Won’t Increase Revenue

The brief article alleges to summarize what I said in an interview. My first reaction was, I didn't say that. My second reaction was, did I misspeak? Fortunately, the audio of the interview is right there. So I listened to myself (always a painful experience), and I think I said what I really believe--that tax hikes do not generate as much revenue as you might think. The Bloomberg headline is an unfortunate misrepresentation.

This kind of thing doesn't improve the incentives for getting involved in public policy.
