The abstract “intelligence” is so ill-defined that it’s as good as impossible to prove any intervention helps improve it. This question is about “Intelligence as measured by IQ”, though. That’s fairly easily improved. To avoid cultural biases, many tests will include mathematical questions, and training on those can have significant impact. For example, knowing the Fibonacci sequence and memorizing multiplication tables, squares, third powers, etc. will help speed up answering “what number comes next in this sequence?” questions (about everybody can continue the sequence “1, 2, 3, 4, 5, …”; fewer will immediately recognize “1, 8, 27, 64, 125, …” as third powers of integers, and even fewer will not have to compute 6³ because they just know it’s 216) |
