It seems to say that where you studied matters if it&#x27;s not a STEM degree.<p>For me, the explanation is that it&#x27;s relatively harder to determine whether someone has learned their stuff if it&#x27;s Math or Science, but quite hard if it&#x27;s creative writing or history. There&#x27;s an xkcd about this.<p>That&#x27;s why something like an online coding test might work: someone clueless will not be able to write that palindrome quiz. You can have a zero false positive rate at the expense of a false negative rate (competent people can freeze in exam situations). With essay subjects, it&#x27;s pretty hard to separate the BSers from the real deal. You&#x27;ll always have some false positives.
