Almost invariably, the experts frame the programme but are not interrogated themselves.
This is such a fascinating realization for me, I have never once thought about the fact that these experts are never once questions. On the show they would just come on say there name and get right into disecting everything about someones life, they themselves never have to answer any questions about their education how they're qualified, anything of the sort. That just goes to show that this 'expert' may not be the exact expert they're said to be, that just what the show wants you to think.
