Lex, dude. time for you to define expert in a smart way or pick another word. "Well informed? Good scientists are humble and well informed and review competing ideas and consider objection to their own ideas, look at pier reviewed content, and know the limits of their knowledge especially outside their field of expertise.  Oh right, I used the word expertise. I would never call myself an expert and experts rarely do refer to themselves as experts.  When someone dedicates their life to the science in a narrow field there is a good word for it. It's called an EXPERT. And after consideration they should reject dumb ideas.  It happens. Get off your high horse.,(reply>), Great guest by the way. Thank you.
