It is when you (apple) gets to look at the jury selection list and chuck ones off you don't want which is what I believe happened based on a piece in El Reg on Friday...
Apple would need idiots on the jury who'd never done anything technical or designery as any designer will say something like 'Well yo'ure not going to make it with sharp corners, that's obviously silly. So, now you know you need rounded corner you UI should have rounded corners to maintain consistency, and now you've decided on icons then a grid is the most logical arrangement..' and so on.
So if the jury selection list shows the jobs and ages of the jurors you can easily filter out the smarter more individual-thinking ones and reject them. Plus comparing their age/sex/etc (if noted on the sheet) you can also select likely fanbois as you know your own marketing demographic.
This assumes they get to toss folks off the jury selection list of course but I think IIRC that's standard practice
