Most scientific studies are probablly wrong

Interesting reading. Its amazing how bad ao many scientific studies are. This article suggests part of the reason is there is little negative consequences if authours publish poor studies but if they sont publish they will likely loose influence, money, and potentially work.

“Dr Ioannidis draws his stark conclusion on the basis that the customary approach to statistical significance ignores three things: the “statistical power” of the study (a measure of its ability to avoid type II errors, false negatives in which a real signal is missed in the noise); the unlikeliness of the hypothesis being tested; and the pervasive bias favouring the publication of claims to have found something new.”
