RE: Cohen's Observation
You are taking causality (rightly or wrongly) to include a statistical
inference based on population studies. I was taking it to mean one whose
conclusions are based purely on the "laws" of science (i.e., causality=you
understand the mechanism which leads you to the result). It would appear
that this is a question of semantics, at least on my part.
Cheers,
Grant

Establishing causality is generally not possible when talking about complex
organisms like humans. If it were, it would not have taken so long to sue
cigarette manufacturers.

The causality of smoking and lung cancer was established in the 50's by Sir
Richard Doll and others.

By the way, Sir Richard Doll has also been critical of Dr. Cohen using
ecologic studies to assess the validity of the LNT.
