‘What gets measured gets done’, according to management experts like Tom Peters. But does it get done at the expense of other–more important–things? That’s the central question of the book ‘The Tyranny of Metrics’ by Jerry Z. Muller. He joins us for a discussion of whether all goods and services in our society can be quantified and whether that’s the best use of precious time. For example, is the new tendency in public education to teach to the test enhancing learning or simply a way to limit the evaluation of students and teachers to a number when society may benefit from a much more robust measure of readiness. Central to the issue is whether using numbers as the predominant indicator assures that they will be manipulated in some way. Take a listen.
