Here is the reason Beloit College keeps producing the Mindset List:
They did it once, in the 1990s, after one of the professors found a similar type of list in an e-mail forward. He passed it along to the English department, who went "Oh, let's make one of these for incoming college students!"
They made the list, published it, and it became minutely famous in academic circles, which over the next couple years, grew into small, but nonetheless national, recognition.
Nowadays, it's the only thing about Beloit College that makes even the tiniest of buzzes on the national scale (aside from their massive budget problems, as reported in Time Magazine last year, and quickly played down by the administration). They won't stop doing it because it gets attention, however small, and if there's anything true about small colleges, it's that they're desperate for press.
