<p>By the time I got through the first few paragraphs, I remembered
that, over a decade ago, I saw the danger of what he calls
"overfitting" in education and coined what I called "the implicit
motto of education reform":</p>

<p><i>If you can't measure what you value, value what you can

<p>So I was not surprised to see education as the first on the list
of examples of the the danger of overfitting in section 3.</p>
<p>I'd not read of Goodhart's Law, either the weak or strong forms,
but I had discovered the idea. It seems increasingly important to
keep in mind as technology makes it ever easier to measure things.
A few examples I don't think I saw in the article are measuring
executive performance by measuring quarterly financials or
measuring software engineers by lines of code.<br clear="none">
