On Nature vs. Nurture, the author makes a great point. Not only is the case for nurture growing stronger, the BELIEF that ability is not fixed is a strong predictor of improvement over time. In other words, when we FOCUS ON the nurture side of things and decide that we can better our circumstances, cognitive abilities, performance, etc., we can.
As a society, this points our attention toward the aspects of our inheritance that we can actually affect. It points us toward the way we take care of our children, how we love and root for those in our lives, and how we hold ourselves. It points toward the disempowerment that can come from labeling and pathologizing.
Of course, in the nature vs. nurture argument, there are two sides. The question here is, which side can we do something about?
