Most important I even learned in physics graduate school was "physics research has many more 3 sigma effects than it should." Part of it is that if you do 100 searches you are going to see one three sigma effect. Couple that with reporting bias (only the interesting stuff is reported).
- JoshTriplett 15y agoAs far as I know, 3 sigma implies 1 in 370, not 1 in 100. (Still insufficiently unlikely for a conclusion.) https://en.wikipedia.org/wiki/68-95-99.7_rule https://en.wikipedia.org/wiki/68-95-99.7_rule
