But that was just what the scientist already did. Featured on Meta. The only way to avoid finding evidence for H, for a Bayesian would be to have a low prior in H. In some journalists demonstrated the same problem: just how gullible other news outlets are with the same sort of flawed “experimental design”: How, and why, a journalist tricked news outlets into thinking chocolate makes you thin – The Washington Post. The exact same picture as in panel 2 above. Is the “e” in “News” supposed to look like an epsilon and the “w” a rotated epsilon? If it were me, I would probably have started with a smaller-palette brand, since their colors affect everyone who eats jelly beans, and not just the ones who go for the gourmet brands. What people overlook is that the actual p-value for the green jelly bean case is not.
