Very cool idea. How hard would it be to process the data in a meaningful way? Are you familiar with the psychology behind it? Is it "standarized" somewhere or rules of thumb that most people agree on with jury selection?
"I have a complex case, I need smart jurors" or "my case is based off emotions, not facts, so I need emotional jurors" are common thoughts. Because of this any insight into the potential juror is useful.
There is a great deal of rules of thumb. Strategies passed from attorney to attorney, but little verified knowledge. That is what I'm hoping I can provide.
