If the conversation is handled carefully, I can see what you are saying polarbear. But I think it should not be over-done and a discussion of effort is also in order, or the bell curve or IQ score is meaningless. Kids who are lower on that bell curve but more motivated may end up doing much better in the long run (and are truly the "gifted" ones in the end). Dh's brother was a national merit scholar and his mom was always talking about IQ scores of various people. Her national merit scholar ended up dropping out of college with various "F's" and "Incompletes" on his transcript and now he drives an ambulance part time after living with mom and dad til age 30.
Dh's brother was/is 2e and has ADHD. His mom was always using the ADHD to excuse laziness, underperformance and all kinds of behaviors. I hope to handle it much better (both of the "e's")in my own kids.
