[quote=Anonymous]If you read the responses to the tweet you posted some people have some evidence — but you can’t control for the selection effect. Parents believe that the cohorts will be better/more serious/less disruptive and choose schools with tracking, or magnets believing the education will be better. It isn’t clear that it is, but by then confirmation bias creeps in, people convince themselves and we go in circles endlessly. [/quote]
