I know that people can and do learn new things, and I don't expect people's expertise to only be defined by a qualification they gained years ago. But, I think Gladwell's PhD topic and subsequent promotion of TENS says a lot about the way he thinks. The evidence for the effectiveness of TENS is extraordinarily like the evidence for the effectiveness of GET and CBT for ME/CFS. That is, there is no good evidence. We discussed it here:
United Kingdom: ME Association news
Dr Gladwell presumably spent three years evaluating the evidence base for TENS and concluded it was wonderful. If ME/CFS charities want to look and sound professional, they should not hold people like this up as experts in ME/CFS.
Thanks for posting this. I think it is relevant to the approach to research and potentially vulnerability to confirmation bias (the odd person raving that 'they'd be lost without their TENS machine doesn't mean those people aren't also taking painkillers or other things they require, and doesn't extrapolate to all the people who don't come back to the person who is telling them to keep trying it a different way).
My main mentioning was because to be able to register for British Psychological Society accreditation then degrees have to cover quite a specified list which is broad (and certainly not limited to just the clinical or health psychology) and statistics/experimental design must be a significant proportion too.
As far as I'm aware psychology as a degree is misunderstood and should have a very strong focus on methodology because as I remember on one of the first lectures we were told that the thing about studying the brain is that you can't do it / get much out of finding out what does what or how it works by looking at an autopsy.
And because even if you ruled out all the other factors (social in particular) then most tasks are complex ie layered with regards to parts of the brain that they involve.
Anyway, I got the impression that most in the science are not impressed with personality research. And maybe clinical - I guess it is the residue from its context - is the only one that is using correlations. Even in health psychology many years ago you'd have the mention of back in the day talk of 'Type A, B' etc and how they've been 'moved past'.
The point is that all these different areas and themes I guess were supposed to teach different lessons and approaches and where things have gone wrong so that you are approaching them critically ie looking at their different methods rather than learning theories off by heart from Freud, Jung, Piaget. It was about whether any of those ideas were testable. You can't start jumping in using MRI scans without having some sense of the layers involved with different tasks and eg the make-up of the visual system/eyes and individual differences and so on. Stuff such as game theory, which I imagine being aware of would be key in how you design tasks too.
There was the scandal of false memory syndrome. Heck there have been a lot more.
