Interesting article from The Economist on the reliability of our scientific system. Apparently the system is constructed in a way that encourages sloppy work to some degree, and discourages replication of reported research. And peer review is not all it’s cracked up to be. Enough lazy or incompetent researchers—combined with lazy or incompetent peer reviewers and nobody trying to reproduce the results—adds up to bad science.
I find it interesting the most of the unreliable research cited is in the fields of psychology and pharmaceuticals.
