Statistically stupid

The Heritage Foundation "reanalyzed" data from a previous study that shows equal STD rates among virginity pledgers and non-pledgers. Ah, but be warned, los punditos say:

The Heritage studies have not been submitted to a peer-reviewed journal for evaluation and publication, but several independent experts who have seen the studies are reportedly concerned that the foundation's statistical methodology was "flawed" and the evidence "lacking" to back up their conclusions...

Astonishingly, the doctors who conducted the studies used an alpha-level of .10 to establish statistical significance. I was taught in graduate school that anything higher than .05 is unacceptable...

As was I.
