The article is extremely misleading, I dare even say almost malignant.
The study itself claims:
- fluid reasoning and working-memory capacity explained 34%
- language aptitude (17%)
- resting-state EEG power in beta and low-gamma bands (10%)
- numeracy (2%)
They take math skills to equal numeracy. The study itself implies this too. I disagree on a fundamental level with that. Math skills align much more closely to fluid reasoning than to numeracy.
