Nelson's remarks exemplify a disturbing trend amongst technologists, and especially those trying to reform education: Misidentifying sub-par educational experiences and areas of studies as "the liberal arts," and then attributing insufficient outcomes to the liberal arts themselves.
If he went to Wharton Business school for undergrad, he does not have a liberal-arts education. History and literature are liberal arts, business is not. Yet he blames his lack of growth during undergrad years on the very same:
>My first six months, what did the consulting firm teach me? They didn't teach me the basics of how they do business. They taught me how to think. I didn't know how to check my work. I didn't think about order of magnitude. I didn't have habits of mind that a liberal arts education was supposed to have given me.
Perhaps he thinks he studied the liberal arts because he majored in Economics. But majoring in Economics within a business school is, as Wharton's website proclaims, a specialized, business-focused approach, which the site's copy actually contrasts with "a liberal arts setting." [1]
Such programs can't be grudged for failing to cultivate the mind, as their sole aim is "appl[ying] business methods and economic theory to real-world problems." Business programs will always fall-short of real-world experience in teaching business skills, since one is actually real.
If he had studied an actual "liberal art" like philosophy or history or French, he might have gotten the mental development that his program apparently lacked. I think those of us who truly delved into liberal arts programs, with the accompanying rigor, breadth of study, and dedication to teaching, found them a great boon to our mental capacities.
Edit: Another trend that's been irking me lately: the idea that you can "teach" someone to think through "critical thinking" classes:
>In the Nelson dream curriculum, all incoming students take the same four yearlong courses. His common core won't make students read the Great Books. "We want to teach you how to think," Mr. Nelson says. A course on "multimodal communications" works on practical writing and debating skills. A "formal systems class" goes over "everything from logic to advanced stats, Big Data, to formal reasoning, to behavioral econ."
There's a reason that "Communications" programs have a reputation for being full of fluff. If you want to learn how to communicate, communicate. Trying to "study" it isn't get to help you personally. If you want to learn how to write, write about any subject, and have your teacher tear your work apart. Communications skills are taught through experience. You can't sit down and "learn" writing skills.
