I assure you it isn't the case. Amongst physicians there's a cross section of the entire society when it comes to intelligence. The only common thing between them is that they study for a long time and while intelligence may be very helpful in this process, isn't actually necessary.
I'm not saying Cronios is not intelligent, on the contratry, he's excellent at what he's doing. When I left the forum few years ago, he was trolling hard and everyone got into a futile conversation with him. I came back and still see the same thing. People are still discussing with a user who argued for the whole last season that we play with a 4-4-2 formation, that Matri is a support striker, which means he's not even watching the matches, yet presents himself as the biggest fan. He claims that coaches like Ferrara or Conte only agree to accept the Juventus job because they are selfish and care for money and not for the club, that Ranieri was just a pawn manipulated by mastermind Secco, claims that Agnelli is unable to run the club that just won a scudetto after an unbeaten season. And everything that combined with the loudly manifested confidence he's always right and everyone else is wrong. And yet people still feed the troll, throughout the years.
