He did consider this: >I have three non-mutually exclusive theories for this: > 1. The people who come to a psychiatrist are disproportionately the unhappiest and most disturbed. This is obviously true to some degree. But I got the same sort of people when I worked in general medicine and primary care. Even the people who come to a primary care doctor are going to be a little biased towards the sorts of conditions that produce or result from sickness, but people were still much worse off than I thought. Later on he runs a sample of twenty people to get an idea of the type of issues others around us might be facing using the statistics he provides earlier on.
