This post is a perfect example of a common misunderstanding of what intelligence is.
A lot of people think that "being smart" is the same as "knowing things." As if you can take a stupid person and just wipe books on them until the knowledge is absorbed and then they become smart.
When you bring up racial IQ differences, people will commonly argue they exist because of "access to education."
Intelligence is actually [what the brain does with information], not [how much information has been shoved into it].
Zy, a stupid person could never have a smart things transmitted to them. They would never know what to do with the information, the same as if you showed it to a dog.
A smart person does not need to figure things out on their own from scratch. They just use their brains to learn from other smart people.
Are you smart or do you know a lot of things smart people figured out and transmitted to you?
