Interesting article. I noticed that the swimming episode didn't mention any conversations of encouragement, but rather a discussion with the instructor who was the one to put forth positive reinforcement. There is nothing wrong with telling a child they are smart. The problem is ending it there. I believe that many parents who are already taking notice of their childrens academic abilities will be making positive comments as well. There are some children who need to hear that they ARE smart ! Perhaps your poster should say "Encouraging things to say to your children" and leave it at that.
