He calls himself a "real scientist" because he has a bachelor's in Marine Biology and he was a lab assistant at the University of Texas-Austin for a couple years, running errands. He took the cards they made up for him and inserted them into the machine, so he says he designed the t-test used for some study, I forget what it was. But he is named in the paper as being a lab assistant. That's the extent to which he has credentials.
Oh, and he also says he published a paper on climate change 40 years ago describing climate today. It was for a class assignment though at the University of Tampa.
Oh, and he will say he's a published columnist because he had some schizoid scribble published in 1985 where he was ranting and raving about rich people on Venice Beach. He says that this is the basis for the CIA shooting him, but as Jenny Kastner (the woman who saved him, and oddly enough, lil Peep's grandma) says, "he was rooting for garbage to eat behind a crackhouse, so crack dealers shot him".
These are his credentials. Eating trash and putting cards into a machine.
