>Don't we (1) identify something that
might have a health effect and (2) then
look for a population in which that
health effect might occur, whether it
is actually observed or not?

1) Start with the answer, and then 2)
derive the question. A lot of highly
educated people have made their living
for a lot of years doing this. While
such studies can yield good indications
of associations and suggest avenues for
more detailed research, what amazes me
most is people seem to think these
studies yield unchallengable truths.
