Researchers representing a wide range of disciplines and statistical perspectives—72 of us in total—propose to redefine statistical significance. For claims of discoveries of novel effects, we advocate a change in the P-value threshold for a “statistically significant” result from 0.05 to 0.005. Results currently called “significant” that do not meet the new threshold would be called suggestive and treated as ambiguous as to whether there is an effect.
The tension between traditional and Western medical approaches may have large implications for global health. An evaluation of a hygiene information campaign in rural Pakistan shows that while people with weak traditional medical beliefs responded strongly to the program, people with strong beliefs did not.
In this post, we explain the rerandomization procedure and provide an example to illustrate its benefits. This topic will be of interest primarily to those involved with RCTs, and those interested in a relatively new, advantageous, and intuitive method for randomizing units into treatment groups.
The Center for Economic and Social Research at USC hosted the largest conference ever convened on the use of genetic data in the social sciences. More than 90 researchers from a wide range of disciplines discussed how polygenic scores (measures constructed from genetic variants across the genome) help predict behavioral traits.
