1. Logic test. Logical reasoning allows humans to impart their thought and ideas, to communicate in a constructive way, and to negotiate when interests are conflicted each other. On the other hand animals that cannot think logically can never be reasoned with. They simply want something and that's it. You can try to manipulate them or you can beat them into submission. But in real life it means you endorse lies, scam, oppression, and wars. Therefore. We need to make a basic logic test and force all people to take it at some age. And then we shall purge anyone who can't pass it. This will solve about 80% of humanity problems immediately. 2. Humane selection. Pure eugenics and selection is dangerous as it's quite clear that managerial decisions are never holistic and miss a lot of nuance. But we can take all ugly, stupid, uncouth, sick, and overall trash people and import them somewhere else. Let's say, we strike a deal with Congo and will send all such people there, no matter their citizenship. It's also quite easy to find such people: just send there all the poor. As all poor are always flawed in one way or another: they're ugly, or lazy, or stupid, or have low self-restraint, or unsociable, or conflicting, or toxic, or aggressive, or prone to commit crimes, or have some physical or mental disability or illness, and so on. Just set a clear threshold for citizens that are allowed to live anywhere to the North of Equator, and then send the dregs to Congo. Simple and elegant. This way we will create a highly cultured and very civilized paradise which will be beneficial to everyone, including the poor. And also, as we don't physically kill those social swills it will be humane. And it will be quite safe as if we find out that some particular negative traits are actually necessary for a healthy society then we always can change our mind and take some of the rabble back. What do you think, Bernd? Also, do you have any other elegant, simple, and uncontroversial ideas about a way to improve humanity?
