I haven't read the whole article yet, but my understanding of the neuroscience is that people have tendencies towards certain behaviours, but that like a learning disability or any other psychological problem, knowledge of the problem is just the beginning. One can learn to adapt, to cope, with such tendencies and to mitigate them. There may also be ways to treat such tendecies with soon-to-be-developed medical therapies.
Understanding the source of these tendencies and understanding them mitigates some blame, but certainly doesn't remove responsibility. No more than being short does.
