The problem of false positives

The problem of false positives

1. Authors must decide the rule for terminating data collection before data collection begins and report this rule in the article. …

2. Authors must collect at least 20 observations per cell or else provide a compelling cost-of-data-collection justification. …

3. Authors must list all variables collected in a study. …

4. Authors must report all experimental conditions, including failed manipulations. …

5. If observations are eliminated, authors must also report what the statistical results are if those observations are included. …

6. If an analysis includes a covariate, authors must report the statistical results of the analysis without the covariate. …
The Lombardi 2009 Science paper violated at least 1 (which matters) and probably 4 (which does not matter, as they were measuring a contamination lab artifact anyway...).

Comments are most welcome! But please:

- No SPAM whatsoever, no supplements, no pharmaceuticals, no herbs or any other advertisements

- Absolutely no quack-doctors pushing their quack-BS websites (and if you are a quack, I will call you out)

- Be critical if you want to, but try to be coherent

Comments are moderated, because I am tired of Gerwyn-V99-The-Idiot and his moronic sockpuppets, and tired of the story of the two dogs, but I will try to publish everything else.

If you are not Gerwyn (and want to tell me something other than the story of the two dogs), then relax and write something! :-)
