The motive is clear, but consequence is that we deliberately choose juries that are fully Dunning-Kreugered. They have to rely on social cues as such to reason about which expert witness is credible... which pretty much undermines the justification for bringing the expertise to court. If you brought in a magician instead, the jury would find them equally credible.
