Those linked basic claims look well falsified already.
People always believe that all of their intrinsic goods will be achieved...This is, according to Connection Theory, an inviolable law of the mind.
Wishful thinking is not THAT ubiquitous and unbeatable. Lots of people expect to die without an afterlife and wish it wasn't so.
According to Connection Theory, the sole source of a person’s irrationality is that person’s need to believe that all of his or her intrinsic goods will be fulfilled. This need is a constraint; given this constraint, everyone forms the most reasonable beliefs that they can on the basis of the evidence they encounter
Falsified all over the place, by most of the heuristics and biases literature for one, unless "that they can" is interpreted in a slippery fashion to describe whatever people in fact do.
According to Connection Theory, every action that every person takes is part of an implicit plan for achieving all of that person’s intrinsic goods. A person may pursue some intrinsic goods first and others later, but none can be permanently sacrificed
This looks like it denies that people ever make real tradeoffs, but they do.
Got it in one.
The plan currently revolves around using Connection Theory, a new psychological theory, to design "beneficial contagious ideologies", the spread of which will lead to the existence of "an enormous number of actively and stably benevolent people", who will then "coordinate their activities", seek power, and then use their power to eliminate scarcity, disease, harmful governments, global catastrophic threats, etc.
That is not how the world works. Most positions of power are already occupied by people who have common sense, good will, and a sense of responsibility - or they have those traits, to the extent that human frailty manages to preserve them, amidst the unpredictability of life. The idea that a magic new theory of psychology will unlock human potential and create a new political majority of model citizens is a secular messianism with nothing to back it up.
I suggest that the people behind Leverage Research need to decide whether they are in the business of solving problems, or in the business of solving meta-problems. The real problems of the world are hard problems, they overwhelm even highly capable people who devote their lives to making a difference. Handwaving about meta topics like psychology and methodology can't be expected to offer more than marginal assistance in any specific concrete domain.
