I meant the method, not the benefits - that one kid reading at 3yo doesn't say anything about the method used. Also, that paper classifies early as starting reading between 0-7yo. Also, in twin studies they show quite high heritability compared to environment impact (which is higher to be fair). Also the impact they showed was between early reading and positive outcomes, but it doesn't show that (simplifying) you can make kids read earlier in some ways. So it's an interesting study, but it's not really discussing "How I taught...". It's (simplifying) "do early readers have better life", not "can you use method to give kids better life via earlier reading". (Which may still be true!)
