I'm not an economist, but as a left of center libertarian I'd caution that an obsession with metrics and measurement can introduce biases (often biases that encode subtle class-based prejudices) about what one is measuring with an implicit mentality that what is being measured is an accurate metric for the desired subjective outcome, which very dangerously can slide into a mindless optimization exercise of the metric that gets so detected from the original intent that it begins optimizing for something antithetical. It's not quite praexeology, but I definitely came to this belief through listening to critical rethinking of econometrics by Austrians.
