We Need Science In Medicine

One of the prevailing myths of modern life (I use the word here in the sense of something that everyone believes, not necessarily something that is false) is that cholesterol causes heart disease and stroke, and that reducing it will reduce the risk of heart disease and stroke. But the recent Vytorin issue should give us cause to question this conventional wisdom.

Whenever I’ve looked at the research, I’ve never been able to see any clear indication that taking cholesterol-reducing medication actually reduces risk, per se–all that the clinical studies that I’ve seen seem to indicate is that cholesterol reduction is taking place. But correlation is not causation. It could be that both high cholesterol and vascular disease are caused by some third factor that hasn’t been identified, and that in reducing cholesterol, whether by diet or medication, or both, we are treating a symptom rather than a cause.

My point is, that I don’t know the answer. But I don’t have a lot of confidence that the medical community does, either. And I remain wary of taking medications with unknown side effects and potential for interaction with other things I ingest, when the benefit is unclear. And I write this as someone who lost both parents to heart disease (my father’s first heart attack occurred when he was about forty five, and he died from a second one about a decade later). But they also had much different lifestyles than I did–they grew up with poor diets during the depression, they both smoked like chimneys, and they were both overweight. So I don’t necessarily believe that genetics is destiny, at least in this case.

Irrational Economics

Michael Shermer, who has a new book out on the subject of the evolutionary basis of markets, has a piece on why we often make foolish economic decisions. Envy counts for more than money, apparently.

More evolutionary psychology: why the pill has reduced the need of men to marry.

I’ve often pointed out that the people who really change society are not the politicians and ideologues, but the engineers.

[Update in the afternoon]

I thin that the first article provides a good example of why, despite their irrationality, socialism and wealth redistribution schemes are so intrinsically appealing to so many, and why they won’t die out, despite their manifest empirical failures. Too many people would prefer that everyone be poor than that a lot are wealthy while a few are superwealthy. Which is sort of depressing, because it means that the ideological wars over this will go on as long as human nature remains what it is.

“Who Says Nothing Exciting Ever Happens In Canada?”

That’s Joe Katzman’s comment at this interesting post by Donald Sensing on a major asteroid impact in North America thirteen thousand years ago.

…the worst consequence of the cataclysm was the mass extinctions of the late Pleistocene that have heretofore been attributed to overhunting by the Clovis peoples of the continent. The extinctions were additionally blamed on the Younger Dryas. The new impact theory, though, says that the comet’s multiple explosions (caused by its breakup in the high atmosphere) themselves caused the extinctions: “at least 35 genera of the continent’s mammals went extinct
