Very interesting. So if you want an intelligent model, you should train it on data that gives a high IQ score. You can then test a text to see if it increases or decreases the IQ of a model, if included in the training set. This makes it possible to classify text as "decreases intelligence" of "increases intelligence". Logical next step is to mark books based on the expected effect on intelligence.
