2021-04-23 - measuring vs. setting goals

about a year ago i wrote a short post on measuring KPIs... up to a point, where i've compared KPIs to Heisenberg's uncertainty principle. today i've learned it's actually formalized and beautifully put by Goodhart's law:

Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.

and Marilyn Strathern's generalization of it:

When a measure becomes a target, it ceases to be a good measure.
