Some poeple accept their duty
I have a very high-earning US friend who got called for jury duty. Months and months later, went back to work, as he got a murder trial. He said he did is as it was his duty as a citizen. He could have got out of it, but he didn't try.
Do you really think smart people should avoid jury duty? Juries have lasted over 1000 years in England because they get justice done. Not 100% but if I were up in court, I'd want a jury trial.
