It's a messy issue with no perfect solution so non-experts are the best solution so far.
Really? Why not? Do you have any citations to back this up?
How come? In a case where it's important to know whether a patent was infringed upon or not (call it a technical thingie happened or not) it's very important that the very facts and formulas behind this were needed to be carefully understood by people who gave the verdict(I am not aware of the USA jury system other than explained by Hollywood).
Atleast they could have seen what a patent farce war it was. Now all they might have done was "Oh yeah.. looks like Samsung copied Apple.."..another "..yeah..seems like that..hmm you are right".. "a billion dollar will be fine..no?".. "yeah...that's perfect.. let them pay a billion dollar".. or whatever happens inside there.
You could apply the same argument to any other kind of task. "If we decide that a certain kind of person should perform certain surgeries then that creates a new kind of class system and would hurt us more than help." So, if jury trials are a good thing, that's not for the reason you gave, since you obviously wouldn't want random people to perform heart surgeries or design bridges.
I don't know that the current system does much for equality either. For example, back when I used to read reddit there were a lot of stories about how black people are disproportionately likely to be convicted of crimes in the U.S. So if that's true, you can't help but wonder, maybe trained experts could be trained to be more color-blind than an average citizen.
Have you seen the movie "Twelve angry men"? It becomes much less uplifting once you realize that in the real life it will be just like that except there may be no Henry Fonda in the room.
