Science is self -correcting, but it takes a while sometimes.

Couple of famous examples:

It took a long time for meteorites to be recognized for what they are by science. Thomas Jefferson, for one, said he would sooner believe a Yankee schoolmaster would lie than that stones could fall from the sky (that's the schoomaster that reported the fall.)

And there was Semmelweiss, who said puerperal fever could be reduced if doctors would wash their hands. "When he published the results of ten years of observation in 1861, he suffered vicious attacks on his integrity and was forced to flee Vienna. He eventually suffered a complete psychological breakdown and committed suicide."

Offhand I can remember when there were canals on Mars and when excercise was bad for people with heart trouble. And when it was only folklore that cougars screamed. According to science, that is.

I remember the surprise when Benson's research showed that meditation could produce changes in body chemistry.

Right now there's bound to be lots of stuff we know that ain't so, that the self-correction hasn't caught up with yet.
