A call for greater power in an era of publishing negative results.

Historically, medical journals published only positive results from experimentation. With the growth of electronic media, many journals are now able to publish negative results as well. Because most medical experiments are designed to have different thresholds of significance for positive and negative results, this can lead readers to misunderstand the level of significance of a published negative result. We propose a technical shift - setting α equal to β - to avoid this potential for misunderstanding.
