Professor is lauded by right-wing journalists who use study as stick with which to beat then-presidential candidate Al Gore. Research firm working with professor then says data show improvement only for one subgroup of blacks; this criticism gets far less media attention than what professor originally said. Professor writes book ignoring research firm's objections. Lead researcher of firm keeps up criticism. Professor agrees to release raw data. New analysis of data shows no improvement whatsoever for black students on vouchers.
