"Imagine you’re conducting a big study of typing performance. You put thousands of people through a battery of typing tests, then crunch the numbers.

Therefore, you conclude, the best way to avoid making typos is to type as fast as possible." https://www.outsideonline.com/health/training-performance/ergodicity-problem-performance-research

Data. Can't live without it. Can't trust it!
