1) Layoff the attacks on others. Let them be and continue to produce your own excellent reports. It’s OK to point out other people’s mistakes but do so only in passing, saying that you differ from the author — no need to tear them apart.
2) Fixating on other people’s work is counter-productive. You should be busy on your own work rather than spending time reading other’s people writing.
3) It’s not your job to save the world. If might serve you better if others are obviously wrong. Your work will shine all the more. Why would you want to correct them and give away your competitive advantage?
4) People are under no obligation to issue corrections just because you e-mail them. They don’t work for you.
