There's no reason a random dude with a bachelor's in physiology can't be good at media criticism. It's not like the big nerds that go into journalism or join think tanks are beacons of truth. Media criticism is about flexing your skeptical and investigative muscles and being highly informed about the topics in question so that you can do the hardest thing in it: identify what was left out, what was neglected, and what articles were not written instead of what is before you.

That said, this particular random dude physiology major is not good at media criticism.
