Do you mean that there may be some harm in "hiding" from children their intelligence? I can see that maybe at early ages, but certainly they'll eventually catch on with grades and such? I don't know when different parts of personality manifest, maybe some child psychologist can chime in. But my hunch is that maybe not saying anything until grade 2-3 could potentially help. Above all, I think the key is to tell them that it's trying hard that leads to getting what you want. Obviously that's a bit of a lie, but I think acceptable until a later age.

Totally agree. This is now the approach I’m taking with my 4 year old who is clearly quite bright.
