This article strikes me as completely worthless, especially the phrase "learn from your mistakes" as a general category. Let me give two simple examples that parents have almost no influence over that require a child to "learn from mistakes." Walking: a child has to fall down a lot and understand how to lose balance slightly to be able to walk forward. They may observe others closely but they have to learn walking from their own mistakes. Speech: many adults around a child may correct speech, but over time children have to auto-correct for the most part. You would think you would find a correlation between delayed development in walking and speech and fewer dopamine receptors but I am not aware of any studies that would support that correlation and I have had good reason to look into causes for delayed development. Here is the only link between studies and "learning from mistakes" that the article offers, and it's problematic: "Numerous other studies have linked this gene variant to addiction, obesity and compulsive gambling, suggesting that the underlying problem is trouble learning the negative consequences of your actions." Addiction, obesity, and gambling all have the property that they are associated with short term pleasure and long term problems. This is very different from being able to "learn from your mistakes." It's possible, for instance, that all three of these activities boost dopamine levels in the brain (as does smoking, another short term pleasure that's problematic in the long run) and counteract the effect of having fewer receptors. I think the real explanation will prove to be more complex (and will need to be evolutionary stable in the same way that dyslexia confers considerable survival advantages).
