The last time I was called for jury duty during the selection process we were asked to state education and career experience. As I was speaking someone blurted out “oh, your a smart one”. I was dismissed. Came to find out later it was the judge who made the statement. They want a jury of morons.
Depends upon who "they" are.
I have served on two separate petit juries; in both cases, my science & engineering degrees were fully disclosed to the court. Nobody seemed to care one way or another.
