Gatekeeping at Faraday’s Cage

[I]t bothered her that in the sciences and engineering there are often classes used as “weeders”, the principal being that the “unfit” are not able to survive the rigors of the fundamentals classes and will drop out before too much time and money has been invested by either party.

The teacher called this “gatekeeping”. It’s a concept with which I am familiar because, unfortunately, I’ve been on both ends of it. I also have a lot of mixed feelings on the topic, and it helped me to hear that this philosophy bothers other people.
