Unfortunately the author has totally messed up on the marshmallow analogy, and it ruins the article. The characteristic of having self-restraint (to delay gratification e.g. eating the marshmallow), is completely and utterly different to the characteristic of having "self-regulation" (to obediently comply with whatever society's, or school's, expectations for conformity happen to be at the time).
That said, when we were looking into schooling options for our oldest we soon realized that B&M was absolutely not going to work for our "nonconformist wild child".
