how to deal with revisionism?
RyanMcGreal: If you think it's an important issue, read up on it. Read arguments from people on as many different sides of the issue as you can, and be sure to read up on the responses to those arguments from different sides of the issue.Pay attention to peer-reviewed studies and meta-studies - look for data that you can study and verify.Pay attention as well to the manner in which arguments are made. If an argument resorts to informal fallacies like ad hominem attacks, cherry picking data, bait-and-switch and so on, be even more highly skeptical.It's also important to understand whether the person making the argument has any conflicts of interest (e.g. their own paycheck depends on a particular point of view taking precedence over policy). However, it doesn't automatically follow that such a person is being dishonest just because they stand to benefit from the adoption of their particular stance.
