Very well said.

Are you aware of any particular biases that tend to make people slide down the slope from 2 to 4? I find that I often slide down to 3, but rarely slide down to 4...for example, I often categorize death via old age as "not a problem," but will gladly listen to and occasionally fund other people's plans for curing aging; I was in the habit of characterizing a knee condition I have as "not a problem," but when someone called my attention to new evidence suggesting that a particular nutritional supplement reliably improved similar knee conditions, I went out and found a version of the supplement of the pill that I am not allergic to and used it regularly and got good results; I was in the habit of characterizing low interest rates on depository accounts as "not a problem," but as they continue to persist in the United States I have found myself devising policy solutions that might increase interest rates at low social cost, etc.

I am curious whether you think that despite my anecdotal-ly good track record I am still likely to inappropriately shift into 4 (rejection) on other issues, and, if so, what I might do about that.
