I think the mismatch theory is catching on because<p>1) It simply makes intuitive sense
2) There is simply lack of hard data that would disprove it<p>Ie when you place a group of students whose SAT scores are 250 points below the average, in a competitive environment, they will struggle because there is no AA once inside the university. So this is the default &#x27;makes sense&#x27; theory.<p>If it is actually not true - you have to bring data to bear.
