Here it is in the words of current Leverage Institute’s post about their previous work on psychology:
”During our research we encountered a large number of risks and potentially deleterious effects from the use or misuse of psychological tools and methods, including our own. We believe that research should be conducted by people who are informed, as far as possible, with the potential risks and dangers of research, and the use of our tools and methods are no exception.
As such, when equipping others to engage in psychological experimentation themselves, we will endeavor to help people to make informed choices by describing the risks and dangers as we see them, and making recommendations about what we believe to be more or less safe approaches.”

Also: “If you have a bunch of weird(?) people experiment on their own minds and also each other, you would maybe imagine that could lead to bad effects and/or things might fall apart at some point. Perhaps this is why some people found Leverage to be a bad idea from the outset. Well, it took ~8 years (and we learned a lot in the process), but things did fall apart. We did know that going in though, and were aware that things might not work out (though I suppose people were also pretty committed to it working, and planning on that maybe more than they were planning on it falling apart quite so spectacularly).”
