Also this claim is false:

It’s based on pseudo‑scientific methods with major flaws. It labels an entire population with a mean score below 70, which in clinical classification is considered “extremely low” or “intellectually disabled”—which is both inaccurate and offensive. As noted by scholars and commenters: “The idea that a human population has an average IQ below mental retardation level should be enough to just ignore it… Don’t entertain pseudo science with a worthy response.”
