There aren't that many real scientists and anyone who teaches that status has the option of telling the truth and being humiliated, flagged as insane, fired from their job and never working again,
Or
Maintaining the lie and getting high paying jobs with lots of respect and noble prizes with a million dollar reward.
Also people think you have magic powers like time travel and teleportation and are so intelligent normal educated people can't even begin to comprehend your greatness.

So with those two options it's kind of obvious which one you would pick.
