Data doesn't speak for itself. It has to be properly contextualized and positioned for an intended audience and message. It's for that reason that you don't ever see scientific papers that are just tables of numbers alone.

If you're outside a particular area of expertise, the intellectually honest thing to do is to say "I'm not knowledgeable enough to assess these findings" and defer to someone who is. At that point, you're assessing credibility, and affiliation and track record absolutely matter.
