To reiterate: if given a summons by the court, in person attendance is mandatory (applies to all 50 states). After voir dire, if either the lawyer or judge has selected you as the juror and being presented with evidence relevant to the case: what types of cases were you assigned whilst being a part of the jury?
Also, what happens if the individual fails to willingly show up (non-excusals) in court on the appointed date when they’ve been handed a summons in the US? For reference, in my country where Jury Duty also exists: the offense for failing to show up in person incurs the equivalent of an ~800 USD fine.
I was called to jury duty twice specifically in areas I practiced in. I got kicked in peremptory challenges, which sucks because they were cases I was legitimately interested in seeing through to completion, but also I have been called as an expert witness in that kind of case and can and probably would have evaluated the testimony in front of the jury and swayed other jurors opinions. You don’t want an individual juror to sway other jurors. It was good and right I got kicked. But less fun for me. I almost stayed and watched the trials, but I had to work.
