I was thinking that there have been swings of what is valued (or trusted) in education and testing (or voting, promoting) to prove that someone has the goods.

I was thinking that there have been swings of what is valued (or trusted) in education and testing (or voting, promoting) to prove that someone has the goods. At one time it was live oration skill, and then people thought, "maybe that disfavors people who are introverted or whose talent comes from thinking and writing". Then, at another time, it was thought, "well you have to test because sometimes time pressure and not being able to go away to think about something for as long as you have time to work on it produces something valuable". Yet another time, "let people do homework to prove their value through effort who don't test well" but now who knows whether they actually were the ones doing the work? I wonder what this development will produce?
