[Response] Thanks Kele!

I didn’t dwell on that detail in the article—I had in a longer one, but it was edited out—but I mention a couple of things about what you say. Specifically, the issue here is covariance.

The example you give assumes that there’s a very high likelihood that 2 people will pick the same combination of skills. If you consider there are likely tens of thousands or millions of skills you can have, the likelihood is extremely low.

The skills that go together frequently have what’s called a high covariance. I do mention in the article that mastering those won’t differentiate you. The example I give is the journalism one.

Hope that helps!
