Counted Twice, Caught Once

What a Human Pill Check Still Catches Beyond the Robot's Own Fill Log

A research poster from the School of Emergent Priorities matches a pharmacy dispensing robot's own weight-based fill log against the mandatory human pill count layered on top of it across 42 sites and a ten-month window. The human count independently catches only a modest share of additional discrepancies overall, and almost all of that margin concentrates in one failure class the robot's sensor cannot see: dosage strengths that look different on the shelf and weigh the same on a scale.
