I try hard to write with a NPOV - even if an editor is non-neutral, the words should be neutral. Any article, especially a BLP, should be factual and try to provide a balanced picture of the subject. When boiling down a subject into a few pages we have to pick and choose which facts are notable. Some of those may be positive and some may be negative. We should try not to emphasize either the positive or the negative, but should try to present a picture which is a fair representation of the subject.
I believe in the Scientific Method:
The process must be objective to reduce a biased interpretation of the results. Another basic expectation is to document, archive and share all data and methodology so it is available for careful scrutiny by other scientists, thereby allowing other researchers the opportunity to verify results by attempting to reproduce them. This practice, called "full disclosure", also allows statistical measures of the reliability of these data to be established.
I oppose ad hominem attacks:
replying to an argument or factual claim by attacking or appealing to the person making the argument or claim, rather than by addressing the substance of the argument or producing evidence against the claim.
