The most charitable take on it that I can form is a similar one to Scott's on MBTI: (http://slatestarcodex.com/2014/05/27/on-types-of-typologies/). It might not be validated by science, but it provides a description language with a high amount of granularity over something that most people don't have a good description language for. So with this interpretation, it is more of a theory in the social sciences sense, a lens at which to look at human motivation, behaviour, etc. This probably differs from, and is a much weaker claim than people at Leverage would make.
I don't know how I feel about the allegations at the end. It seems that other than connection theory, Leverage is doing good work, and having more money is generally better. I would neither endorse or criticize their use of it, but I think that since I don't want those tactics used by arbitrary people, I'd fall on the side of criticize. I would also recommend that the aforementioned creator not be so open about his ulterior motives and some other things he has mentioned in the past. All in all, Connection Theory is not what Leverage is selling it as.
Edit: I just commented on the theory side of it. The therapy side (or however they are framing the actual actions side), a therapy doesn't need its underlying theory to be correct in order to be effective. I am rather confident that actually doing the connection theory exercises will be fairly beneficial, though actually doing a lot of things coming from psychology will probably be fairly beneficial. And other than the hole in your wallet, talking to the aforementioned creator probably is too.
I’m a member of the Bay Area Effective Altruist movement. I wanted to make my first post here to share some concerns I have about Leverage Research.
At parties, I often hear Leverage folks claiming they've pretty much solved psychology. They assign credit to their central research project: Connection Theory.
Amazingly, Connection Theory is never something I find endorsed by even a single conventionally educated person with knowledge of psychology. Yet some of my most intelligent friends end up deciding that Connection Theory seems promising enough to be given the benefit of the doubt. They usually give black-box reasons for supporting it, like, “I don’t feel confident assigning less than a 1% chance that it’s correct — and if it works, it would be super valuable. Therefore it’s very high EV!”. They do this sort of hedging as though psychology were a field that couldn’t be probed by science or understood in any level of detail. I would argue that this approach is too forgiving and charitable in situations when you can instead just analyze the theory using standard scientific reasoning. You could also assess its credibility based on standard quality markers or even the perceived quality of the work going into developing the theory.
To start, here’s some warning signs for Connection Theory:
I don't know about you, but most people get off this crazy train somewhere around stop #1. And given the rest, can you really blame them? The average person who sets themselves up to consider (and possibly believe) ideas this insane, doesn't have long before they end up pumping all their money into get rich quick schemes or drinking bleach to try and improve their health
But maybe you think you’re different? Maybe you’re sufficiently epistemically advanced that you don't have to disregard theories with this many red flags. In that case, there's now an even more fundamental reason to reject Connection Theory: As Alyssa Vance points out, the supposed "advance predictions" attributed to Connection Theory (the predictions being claimed as evidence in its favor in the only publicly available manuscript about it), are just ad hoc predictions made up by the researchers themselves on a case by case basis -- with little to no input from Connection Theory itself. This kind of error is why there has been a distinct field called "Philosophy of Science" for the past 50 years. And it's why people attempting to do science need to learn a little about it before proposing theories with so little content that they can't even be wrong.
I mention all this because I find that people from outside the Bay Area or those with very little contact with Leverage often think that Connection Theory is part of a bold and noble research program that’s attacking a valuable problem with reports of steady progress and even some plausible hope of success. Instead, I would counsel newcomers to the effective altruist movement to be careful how much you trust Leverage and not to put too much faith in Connection Theory.
