Personnel Selection Utility Analysis 2D

Industrial-organizational psychologists don't just ask "does this hiring test correlate with performance?" — they ask whether using it actually makes money. This 2D simulator lays out a pannable, zoomable scatter of job candidates, each with a correlated test score and true performance outcome, next to a live histogram of the test-score distribution and a utility-vs-validity sensitivity curve. Drag a hiring cutoff across the scatter and watch the Taylor-Russell success ratio and the Brogden-Cronbach-Gleser dollar utility formula respond in real time to the test's validity, how selective the hiring bar is, and how much one standard deviation of job performance is actually worth.
