### Goodhart's Law
[The Goodhart's Law on Wikipedia](https://en.wikipedia.org/wiki/Goodhart's_law)
> Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.
>
> _Charles Goodhart_
Also commonly referenced as:
> When a measure becomes a target, it ceases to be a good measure.

The law states that the measure-driven optimizations could lead to devaluation of the measurement outcome itself. Overly selective set of measures ([KPIs](https://en.wikipedia.org/wiki/Performance_indicator)) blindly applied to a process results in distorted effect. People tend to optimize locally by "gaming" the system in order to satisfy particular metrics instead of paying attention to holistic outcome of their actions.
Real-world examples:
- Assert-free tests satisfy the code coverage expectation, despite the metric intent was to create well-tested software.
- Developer performance score indicated by the number of lines committed leads to unjustifiably bloated codebase.

Coined by Wil Wheaton (Star Trek: The Next Generation, The Big Bang Theory), this simple, concise, and powerful law aims for an increase in harmony and respect within a professional organization. It can be applied when speaking with coworkers, performing code reviews, countering other points of view, critiquing, and in general, most professional interactions humans have with each other.

Principles are generally more likely to be guidelines relating to design.
