Why is it so hard to accept that domain transfer does not exist. If kids learn chess for a few years, they won't be better at mathematics. That seems like the wrong way to look at it. I taught my son chess and music, not because I wanted him to be smart. But because I want him to have fun. He was already smart. I also taught him many other things of different types, games and sports, most of them what I find fun, some of them he liked, some he didn't. Are chess and music useless? I don't think so. There are a handful of lessons to learn there that are useful for other domains. Is there no other way to learn them? Probably there are, but it's way easier to learn them as part of a fun activity than sitting in a class.
