No. The world needs more HONEST historians that don't have their work discredited. Simply because it is an accurate historical portrayal of uncomfortable dangerous facts without fiction.

Honesty is too complex to be a requirement. Having people discredit your work is out of your hands. I'm not actually asking for our history books to be more accurate, because this is implausible. I only wish that people do enough of their own study to avoid being played. It's a minimal goal with properly aligned incentives, and yet a sadly high bar compared to the status quo.
