Jackson Lahmeyer has obvious serious psychopathologies:
Most likely dark triad in this case, but possibly APD psychopath subtype with psychotic spectrum traits.
(Put another way: On a HEXACO test this guy's H score - if captured properly - would be 0.)
This level of intellectual and epistemic dishonesty in a public performance really requires the dark triad traits special to Voltaire's scoundrels. It would be very difficult for a person to be this badly split from reality in the schizophrenic sense and still able to articulate themselves confidently and fluently.
However, there's always Kurt Godel, Philip K. Dick, and John Nash to consider. Notably however, none of those three exhibited dark triad traits. This guy is dark triad for sure. Moreover: I doubt he's as intellectually agile as any of them. Certainly not Nash or Godel.
