Not just the double-slit for quantum mechanics, but it applies to people too. In a workplace, the second you start evaluating performance based on a metric, it ceases to be a useful metric. Why? Because people will shit the bed willingly in every other aspect of their job if it makes the number their boss looks at better. At that point, “highest performers” are really just the best bullshitters who can fake short-term benefits in lieu of long-term solutions, and all of them just make things worse overall.
