Hello, dear Dana, I am very glad I found your blog. There are many interesting posts.
I took workshops in criminal profiling. From what I was told there are about 21 % psychopaths in high business positions and around 7 % in the rest of the social ecosystem.
If we look exactly their most specific sides, one of them is that they are very hard to identify. They are not loud as the sociopaths, they are often not the boss, but his assistant who is adorably kind to all, or the neighbor asking if you need help with the shopping bags, their brains work differently. Many of them look like sweet ordinary people. Some humans have a psychopath's brain, but luckily don't get triggered and don't develop it in a dangerous way. To be honest, I think in the next 50 years nothing will change. What might change at some point in the far future could be brain scans already in kindergarten to see if some of the children have such a brain and treat them in a way to prevent possible dangers in the development.
Here a video of a psychopath child, who had very successful treatment and became a well functioning happy woman.
