I have been to jury duty multiple times AND I was never asked about it while under oath. It was discussed but explicitly not encouraged. Hell one time the judge made every one of us potential jurors in the room say nigger under oath with the penalty of perjury if you refused. Being in a room full of people squirming over that is something I will never forget. It was a murder case and the defense was trying to prove that word had power over us and can make people emotional.
