> so the judge develops the intuition that a new defendant is very likely guilty.
A good judge wouldn’t do that. Also by and large random people are relatively dumb and biased. Why exactly are they less likely to convict an innocent person? (Let’s assume that the conviction rate is the same in both cases)
The conviction rate can't really tell you anything because prosecutors will calibrate to bring cases they think they can win in a given system. Systems willing to convict more innocent people will have similar conviction rates but more innocent defendants.

What about a human judge?

Because you have to convince all twelve of them.
