- perhaps the judge make less experts interviews than the corporations, leading to less experience in that but also takes each of them more seriously.
- one way to remove/add some credit to someone claim is to ask some of their peers opinion and see if there’s a strong majority.
- the judge personal expertise may help him forge a precise opinion but that wouldn’t clear him of making a mistake. For important matters it’s always a good idea to ask for peers reviews. Academics knows that too.
This also reminds me of one of Norm Macdonald's bits. He says (very seriously) that if he were on a jury he would not convict someone on the basis of DNA evidence. "What do I know about DNA?" he says.
