The power of suggestion
An article in Tuesday's New York Times references an experiment in which researchers served icy vodka tonics to some college students and icy tonic water to others. Both drinks tasted the same. After two hours or so, the subjects who received non-alcoholic beverages were just as amorous and unrestrained as those who had been downing the good stuff.
Does this study offer any wisdom for fixing our worst k-12 schools? Perhaps telling awful teachers that they are, in fact, actually doing a fine job will impel them to act just as competent as their truly skillful peers? Probably not, but the alcohol study is nonetheless interesting.
