There's a specific world map image that's been been shared about 20 times in the comments and QT of my original tweet, that claims that the average IQ of entire continents is below 65 (a level at which you couldn't learn to read or even live independently). The data is from Lynn and Vanhanen. It has been widely debunked, and sharing it is just telling on yourself. Most country averages are collected from tiny sample sizes, often from children, and in many cases from children in mental institutions or refugees camps. The numbers were also arbitrarily massaged when they didn't agree with the message. It's not science, it's "political discourse" (you know the kind)
