The study didn't conclude that there was mismatch, because it didn't measure whether or not students chose differently when given information on their likely academic performance given their level of ability: > In sum, Duke’s private information on student performance is important beyond the student’s grade point average, affecting both the student’s subjective well-being as well as the likelihood of persisting in a difficult major. It is important to note, however, that we have still only established that some of the necessary conditions for mismatch are met. For mismatch to exist, information must not only be important but the revelation of the information must change the institution the individual would have chosen to attend. Hence, even if individuals find out they are not as academically strong as they thought, the information still may not have changed their decisions. Let's not lose track of what I initially claimed: that lower levels of academic preparedness lead to students changing out of science/engineering majors, and that this was consistent across race. The study did find that this was true. And this was limited to students at an elite university. Mismatch is about what students would have done when given this information, which is not directly related to my claim
