Drinking, forgetting…

June 20, 2014

A clever study asked people both what their usual alcohol consumption is, and what they drank yesterday. With a little statistics, the study concludes that Canadians lie about how much they drink, by a factor of 4(!) if they are low risk drinkers, and a factor of 2 if they drink a lot. That correlates well with the well-known difference between what people report they drink, and what alcohol retailers report they sell. One issue from under-reporting is that it puts to question research that attempts to tie health consequences to drinking, since the latter typically is measured by self reporting. The scale for “amount imbibed” is skewed. (Cite.)
