This idea of what Gladwell might be trying to do in his new book (I haven't read it) is certainly consistent with my understanding of the kind of "laws" that pertain in our human world. In the World of Nature, "laws" really do state inevitabilities. They are "descriptive," and they describe is what must and will happen.
In our human world, "laws" are not descriptive of what "must be," they are "prescriptive," and tell us what we want to do.
Do we want to turn our disabilities into desirable outcomes? I think so! And now Malcolm Gladwell is providing some examples of how that can be done.
