They said East Asians, my comment - given the other statements made in the video I would assume the ability to process more information is due to cultural training - you always process more information, get page with less information seems weird to you, need more information to feel secure that page is way it is supposed to be... thus the ability to process more information is a self-reinforcing cycle.
The youtuber mentions that "Asians" can process information faster than "Americans"
