All the sciences come across as merciless to me. If you make even one statement that turns out to be false, it seems you have no chance of recovering your career. I have heard of plenty of stories of accomplished scientists and academics losing their credentials after making claims that were either rejected from the start or later disproven. I have never heard one story of someone 'redeeming' themselves and gaining respect in any intellectual field. This all makes it look like even so much as a simple mistake can destroy your career forever.
So tell me, is there any route for someone who at some point in their lives supported conspiracy theories or something else obviously false can take to regain respect? I've noticed a lot of psychologists claiming that conspiracy theories are hopeless and impossible to 'cure'. Are the sciences just completely intolerant of imperfection or do they express some mercy?
