Browsing social media, it’s apparent that people are quick to point out problems in the world, but what I see less often are suggestions for how to solve them. At best, I see vague ideas that might solve one issue but introduce new ones, which are rarely addressed.
Simply stopping the bad behaviour rarely is a solution in itself. The world is not that simple. Take something like drug addiction. Telling someone to just stop taking drugs is not a solution.
The reason psychopaths aren’t diagnosed frequently is that it’s simple for a psychopath to fool the test. They have to WANT an accurate diagnosis to get one.
Also, these tests would be gamed to keep specific people out of power. That’s why the restrictions on public office are so low. To prevent gaming.
