Cooperative Crocodiles & Skeptical Bias


After writing recently about the flawed research of Sam Parnia on Near Death Experiences I was accused by a few NDE advocates in the comments section of employing unduly high standards of evidence in my analysis of the studies shortcomings. My critical stance, they argued, was due to a deep ideological bias against the very possibility that there could be life after death or a non-material aspect of human consciousness. Personally, I would characterise myself as deeply ideologically biased in favour of both hypotheses, as I would be very happy if we were able to find evidence that there is life after death and, similarly, who wouldn’t want things like telepathy and out of body mental projection to be possible? As such, the issue for me is not that these kind of findings are undesirable but rather, precisely because they are very desirable, we need to be very cautious that confirmation bias is not seeping into our analyses.

In my experience advocates for psi and other paranormal tend not to appreciate just how necessary a strong critical environment is to the production of good science. A nice illustration of what I mean, is found in a relatively popular trend within academic journals to publish a single long form ‘target article’ which is then followed by a series of short commentary articles from relevant scholars, before the original authors have a chance to conclude with a response to the comments. The point here is that such commentaries typically run the gamut from being congratulatory to being overtly hostile to the theories presented in the target article. I’ve found that this format works well and produces some of the most productive articles for the reader, as it is possible to identify the wider field’s likely response through the microcosm of the commentary pieces. Unfortunately, this kind of engagement seems to be rare in psi and NDE research, with the proponents instead establishing their own journals, which become self citing cliques hostile to any critics- regarded as uninformed interlopers, as opposed to peers with different interpretations of the evidence.

Despite such unfortunate trends, the charge that even self professed skeptics can display notable selective biases in the application of their skepticism is warranted. Indeed, the fact that such a phenomena exists is also acknowledged by skeptics, who have a term for when people are failing to apply their critical perspective to a certain cherished topic; possessing a ‘sacred cow’. For instance, a widespread sacred cow, that I also possessed, is the popular Western perception of Buddhism as an atheistic and scientific philosophical system. I became disabused of such notions, swiftly and painfully, through my decision to study about Buddhist cultures and history during my undergraduate degree but the idealistic portrayal remains all pervasive and crops up everywhere from Academic articles to Russell Brand’s rants (and occasionally, my facebook feed). Although I had that particular cow prematurely slaughtered, it is almost certain that there is a whole invisible herd inhabiting my thought processes and views, just waiting for the right motivation (such as encountering evidence that vitamin pills are of practically no use) to make themselves heard.
