Yeah that's more or less my take. Essentially the court wants a jury of laypeople who are able to understand legal terms that professionals spent years in school studying. They also want jurors to render opinions on things completely without contextual knowledge – the case I was on involved alcohol so having strong opinions on alcohol was a nearly instant dismissal, I've never seen so many teetotalers in my life.

There are people working to change this, and I think the ability to ask questions is a relatively new development, but it's slow going as anything with our legal system generally is.
