No, but I'm not actually objecting to the business management class in particular (that's just a guess). I'm objecting to yet another popular article that treats a narrow study of a non-standard sample like it's ground truth. Generalizing from classmates to friend groups (which are more elective and full of closure/network effects) is totally unsupported, and while that doesn't invalidate the study it certainly cripples the article.
