I always hate science reported in the news because they really don't appreciate what scientific studies really mean.Caduceus Don't make Me add You to the list shirt This study doesn't mean that LSD cures alcoholism. What this study means is that the scientific community ought to run a double blind, properly controlled, study into whether we should devote the resources needed to do a double blind, properly controlled, large sample size study that is designed to be replicated and used in public policy debates, about whether LSD cures alcoholism.

The results of that study will tell us whether LSD cures alcoholism with a pretty good degree of confidence. he of this research is about allocating resources for future research - not proving the topline issue.343 is not a terribly small sample size. What would the margin of error be on that 28 percent? Would it contain zero at 95% confidence?Caduceus Don't make Me add You to the list shirt
Edit: Highly recommend reading the discussion below. Lots of insight about optimal research designs.
Tl;dr: Statistical significance means nothing if the underlying research construction is not randomized or controlled.
