I take any statistics put on the internet with a pinch of salt. I used that map to visualize the differences between nations like Türkiye and Israel in comparison to the rest of the middle east.
Why is it always people from a certain bunch of countries who flee westwards, rape, kill and steal in the country which gave them refugee? Why do they leave their sh*tholes and then preach Islam and attempt to convert others to their religion? If their religion was so good, why are all their nations in ruins? All they can do is blame external forces, never themselves.
These people aren't only going to be a problem for Türkiye, but for Europe and beyond. They're a ticking time bomb.
Whatever the cognitive ability/development is on average for some country in reality (compared to IQ which is just one marker and IQ studies which have flaws in even this limited approach)....there will always be meatheads in sufficient number even in the wealthiest/developed countries....as there are meathead ideologies like marxism and extreme conservatism and all its current and post-modern iterations (that simply do not intersect with the borders of the country and its political framework consensus).
So meatheads in country A tend to want meatheads from other countries to enter and skip the line etc....there is lot of meathead ideology in the end that must "prevail" no matter the cost on the non-meatheads that actually build, sustain and contribute to the country (signing up for the military is one such easy analysis to do on this).
Every country in world needs to have solid migration policy (for controlled legal immigrants, vetting screening naturalisation process etc) and strong policy on illegal immigration. War zone refugees is a tough one to balance in transient situation, but it needs to be fair (once the war is over, they need to return).
I personally take dim view of young males welfare shopping that are from "war zones", why are they here trying to freeload off taxpayers, when they should have stuck to fighthing back in own country to bring war to a close so peace and stability might start again. i.e they are not true fans of their own country, why would they be true fans of yours? Then there are huge numbers not even from war zones in first place, not even that flimsy pretext is there.....just pure economic compulsions to skip the line. Those that want to help other countries can do so within those countries as first basis rather than incentivise short cut illegal stuff (all to undermine own country for their feel good).
If there is a big slip up on all of this (this is common sense stuff known a very long time), it means meatheads have infiltrated enough places of power. The onus is on the larger country to recognise and correct this.
