The Tyranny of Statistics

It's problematic enough that people, even experts, misinterpret statistical data (see Kahneman), but statistical data in the absence of a reasonable paradigm just becomes tyrannical.  We pursue or are pursued by data without rhyme or reason.

Matthew Di Carlo:  One can only cringe at the thought of the groups of hard-working teachers in high-poverty schools being shamed annually by a system that dooms them to low ratings by virtue of their dedication to serving the kids who need them the most.

This is why teachers need to articulate what teaching is.  Without a clear and concise description, the bureaucrats, statisticians, politicians and corporations will decide what it is for us.
