I think China's figure is fake.

They have a huge problem with dietary deficiencies causing low IQ.

Then the teachers are judged by how well their kids do in tests so they are incentivised to fake higher results.

We currently consider IQ below 70 to be a disability, mental retardation...

10 IQ points is supposedly to represent 1 bell curve standard deviation
