Schizo type personalities. Meta magical thinking. Appropriate context. Hearing voices at the right time makes one a "tzadik" (saint); hearing them at the wrong type one gets called "insane."
Cleanliness over done.
All human societies have great need for schizo type personality. They need the shaman. The basis for Torah to the Rambam is objective morality. The cult that the Gra signed the excommunication on turns it into the main thing being ritual;-- especially ritual cleanliness.
Obsessive rituals is the core of the cult that the Gra signed the excommunication on. But what makes the leaders "tzadikim" is the do it at the "right" times. They have enough control over it to make sure it conforms to the social norms that will get them accepted as true tzadikm, and thus get reproductive success and financial security.
Hyper-graphia. Reb Natan was a classic case of the need to write obsessively and an uncontrollable interest in religious matters.
The problem is that every area of value has an opposite area of value that mimics it. So talent can take one only half way. For example; for every science where good work is being done, there is pseudo science. But people in pseudo science are easily able to fool the public because they are talented. But they can't fool the experts. So it is in every area of value,- including Torah. That is why some people emphasize the rituals. That is to be able to fool the public.
So it is important to come to authentic Torah and to avoid fake Torah which mimics it. The schizo personality types of hasidut are never good people. They are not decent people. They are rather good at doing the rituals. That is not authentic Torah.
Hasidim generally are Pre-schizoid personalities. These individuals have visions at the appropriate place and time. The visions are especially effective in the time of uncertainty and crisis. Mild form of OCD. These people follow rituals (in cleaning, eating to allay anxiety. Epilepsy (temporal lobes). These people have keen interest in philosophy and in writing. They also have little or no sense of humor (hm...), stern. Hypocampus damage/development. These people are hypersensitive to dopamine spikes due to random rewards; prone to see agency behind random events. Humans are social apes. Peer pressure, group thinking, and sense of belonging all contribute to development of religiosity.
