Genealogical research and local history studies should be conducted with academic rigour. If you choose to take shortcuts or if you are simply in the business of adding thousands of names, dates, and places to your family tree without due care for the integrity of the sources, then you are doing the family and historical research communities a serious disservice … not to mention, your family tree will likely wind up as a complete fiction.
If any of my findings are not definitive and require further corroboration, I will endeavour to make notations to that effect. Having said that, by using this site, you agree not to hold me liable for any errors or omissions. As a genealogist or historical researcher who subscribes to high research standards, you already know that you should corroborate my findings.
My advice is to read, read, and read some more. Adopt a healthy skepticism in your research approach. Attend a course in research methods. Pick up creditable books on the subject. Finally, you could do worse than Google-ing for such search terms as: genealogical research standards, genealogy standards, sound genealogical research, genealogical standards or proofs of evidence, and so on.
Best wishes with your research!
