That is apparently the case. I've been called to jury duty once in my life. I was actually excited about it. All my work peers cynically said some version of this: "Just tell them you've been to college and you'll be tossed from the pool." I was like, WTF?!? During selection, we were all asked our professions, our level of education, what periodicals we subscribed to, and if anyone in our family had been subject to domestic abuse (it was an wife battery case, IIRC). For whatever reason, we were *all* pruned out, and I never did get to sit.
For the life of me, I can't understand why people with *any* familiarity with a topic should be pruned from a jury pool. If I were on trial for some computer/tech crime, I'd rather a bunch of slashdotters or redditors (gods help me) be on the jury than the uninformed Joe Schmoe who rely on left- or right-wing hate media for their news sources.
