In most societies 'healers' and 'shaman/priests' tend to be associated, if not the same thing.  They tend to be the high-IQ and/or sexually confused weirdos, both of which have an upper hand in understanding psychology enough to use it to their advantage.

In the modern technological era, which is dominated by scientism, 'scientific experts' have displaced the shamanistic spiritual elements, but the practitioners fill the identical gap for the sheeple.  Their own personal particularities transferred over from the 'spiritual elite' to the 'scientific elite' almost perfectly.

What I find fascinating is that the propensity for child sacrifice also transferred over as above.  I see very little difference between a Babylonian 'expert' who burnt children on a golden bull, and Aztec 'expert' to ripped out the heart of kids then threw them down a pyramid, or a hostpitalist or public health 'expert' who injects the mRNA de-pop injection into a 5-year-old kid.  Or 6 month year old when Gates has paid off some more 'experts'.

Even more interesting is the fact that the sheeple will happily and frantically offer up their kids to these 'experts'.  I don't doubt that the same people in the same proportions were running to the sacrificial ceremony in all three instances.
