Very good question Drew. We don't know, of course. We are only able to judge them from the ones that do make the cut. From what I've been able to gather, the BFRO routinely excludes some of the more obvious attempts to hoax. Still, I'm guessing, they err on the side of disclosure on ones that are more borderline.
My conclusions about the report above, after all, is just a spitball lobbed from my armchair. The investigator may have had very good reasons for including it, which we are not privvy to. We all have our own gag reflex settings, after all. I can only say I wouldn't give a report of this kind much weight, but some others may have the background and context to consider it. That is just the really the neat thing about published information. If somebody later provides me with solid reasons why a report like this should be given more weight, I'll reconsider.
I agree with DWA, dmaker, on your point. Critical thinking is why. We either have the capabilities to do that, or we don't, but all are capable of learning it. Otherwise, to quote the Archdruid again, we are just employing a thought-stopper. My point of entry view on Sasquatch evidence is that people are mistaken, people misidentify, people hallucinate, people lie and people tell the truth. Well, that overlays ALL my interactions with humans. Learning to know which is more likely, based on all information available, is the chore.
