Reducing false positives

Razib Khan making sense, including:
  • Authors must decide the rule for terminating data collection before data collection begins and report this rule in the article.
  • Authors must list all variables collected in a study.
  • Authors must report all experimental conditions, including failed manipulations.
  • If observations are eliminated, authors must also report what the statistical results are if those observations are included.
Via Tim Harford.  In addition to professors and doctors, perhaps climate scientists will be more, um, scientific about how they do their jobs.
Statistics are like a bikini. What they present is suggestive, but what they conceal is vital.--Aaron Levenstein
