The Mom Test

The Mom Test

Ignoring compliments should be easy, but it’s not. We so desperately want to hear them that we are often tricked into registering them as positive data points instead of vacuous fibs. ... Rule of thumb: Compliments are the fool’s gold of customer learning: shiny, distracting, and entirely worthless.

The final outcome of the Chicago study is further testament to the power of incentives: the following year, cheating by teachers fell more than 30 percent.
Thinking in Systems

Thinking in Systems

If you define the goal of a society as GNP, that society will do its best to produce GNP. It will not produce welfare, equity, justice, or efficiency unless you define a goal and regularly measure and report the state of welfare, equity, justice, or efficiency.

But here’s the problem: The idea that an improving score guarantees that you’re approaching the objective is wrong. ... This situation, when the objective function is a false compass, is called deception, which is a fundamental problem in search.
