What the Numerical magnitude comparison is
Two fractions, a ticking clock, one question: which is bigger? Magnitude comparison is a classic paradigm from numerical cognition — it measures how fluently your brain converts symbols like 4/5 into actual quantities, under enough time pressure that you can't compute it longhand.
What it measures
Accuracy under the clock reads numeric intuition, and it feeds your decision-making axis: good calls here come from estimating cleanly, not calculating slowly. Wrong-but-fast and right-but-slow are both tells, and the game logs which one you are.
You go on gut and sort it out on the way down.
You'll plan the big stuff and wing the rest.
You see the whole board before you touch a piece.
Why hiring assessments use it
Hiring assessments use magnitude games as a low-anxiety proxy for quantitative comfort — no algebra, just whether numbers mean something to you at a glance.
TELLS is an independent project — not affiliated with pymetrics, Harver, or any employer's assessment. This is the fun version.
