True (at least as far as universities are concerned), but while diversity for diversity’s sake is ridiculous, simply having a mix of people due to various other factors is a neutral. Often when people see ‘diversity’, they assume it was engineered at the expense of academics... and this isn’t always the case. Look in a Computer Science course; it’s plenty ‘diverse’, and academic integrity isn’t sacrificed at all. People automatically construe a variety of ethnicity as either a very good or a very bad thing... but sometimes, it just is.
Yeah, in the sciences/engineering, there are no “diverse for diversity’s sake” people there past the 2nd year, if they don’t have what it takes. I had a lot of good experiences working with people of many different backgrounds while getting my degree.
