I need to start stalking Dario Nardi.... I am SO dying to have my brain scanned. Having a needle stuck deep into my brain sounds like something I might like also.
I can't believe this study has so few people considering the size of the "MBTI community"; I imagine many of us would love to be a part of something like that. Unless people DID have to pay for a course or something (his "workshops" are ridiculous.... around $1300 for 3 days!

).
It wasn't really scanned, it was with electrodes attached to their head and then he interpreted and averaged the results he got. I know what you mean though. And as he said in the video, if he is going to be drawing conclusions from typology, then those types better be correct (or as correct as possible). This means that all of the subjects went deep into typology and were sure of their type. This probably included more than just reading shit on the internet LOL (though one could make a devil's advocate case for it pretty easily). Also, we need to remember that all of his test subjects had to be physically present, in order to do his tests. Plus he needed to make sure that they were sure as well in some way to verify the first point I said. Perhaps he would have liked to expand the pool size, but that was a consideration. Another thing is data consistency - if he looks for more subjects, I would assume he would like to mirror that in all areas (not like "Well I am testing 6 INTPs, meanwhile the rest of the types get only "3 or "I have 4 ESTP, 6 INFJ, 7 INTJ", etc) - with this in mind, it means that he cannot simply add ONE subject to the test. He would at a minimum need to add 16! Multiples of 16! And when you consider that analyzing all of the data took a long time to begin with that is nuts.
Like all colleges, workshops, etc that are extremely expensive, my opinion is you are not paying for knowledge, you are paying for the time to interact with somebody knowledgeable, especially in the physical realm taking place in (prestigious place or whatnot and the reputation it holds > this can transfer to the person speaking putting them in higher esteem). I see it akin to designer clothing (REAL designer clothing, not oh these jeans have a name I don't recognize and are more expensive than other things, therefore they are brand name].
^MBTI isn't science. It's a money-making racket. His sample wasn't tiny because he couldn't find enough volunteers, it's because he had to spend a couple of hours with each person. And too much of that might cut into his "lecture circuit" time.
I wonder how much Google paid him to tell them nothing they didn't already know?
Daaaaaaaamn you are cynical. Gimme a break. First of all, where did you find evidence of his "lecture circuit" attitude? I want specifics. If you have them then I might change my opinion on the spot. So far I didn't see it as that though. I will give you that the one where he talks about the book referenced in this subject's title is a bit of an ad/self promotion, but how else can he talk about something he has done/his own area of expertise without it being that at all? See, I see the expensive lectures as a kind of service... he knows some people might want to pay for it regardless of cost, and he knows he needs money to run tests, so why not give out classes? (even if it's not what he would prefer to do).
(And on a side note, what do you see that kind of reasoning as, the previous sentence? They feel like it's Fi, "I can see how it would make sense with what I value, like how I can explain it into a system that I would value, and how that would translate to somebody else still, therefore it may be true", but at the same time, I think I am more of an INTP because that kind of logic seems idealized "x, y, and z are true (assuming a perfect universe and ideal conditions). I just cannot distill it further between the two - I'll probably make a separate topic on that though, but about this one instance, fi you want to reply anyways you can just PM me)
