Re: The Stupidity of Scientists

There's an interesting paper available ( Why Psychologists Must Change the Way They Analyze Their Data: The Case of Psi ) available that discusses this. That conclusion is essentially that the use of statistics by psychologists is poor. The paper's abstract ends with the note: We conclude that Bems ...

Re: MAY GENII IN THE MAIL A WEEK AGO!
