One of the best ways I eliminate some errors in my reasoning is to go back and look at a conclusion that I have written and look at every part of it that is based on “what I think I know” and what I have some documentation for. Thinking when doing genealogical research is advised. That’s entirely different than thinking we know. What we “think we know” may be based on:
- our own experience (when it doesn’t apply to the problem at hand);
- facts we have remembered incorrectly;
- stereotypes about the family being researched;
- and so on.
Any of these things we “think” we know can be hindering our research.
