Joi Edits on Instagram: "Performance variance emerges when task demands align unevenly with learned skill distributions. In task-execution systems, outcomes depend on prior exposure, fine-motor calibration, spatial strategy, and feedback frequency—not category labels. When a task emphasizes precision, timing, or pattern recognition that one group has practiced more often, error rates diverge rapidly. As micro-advantages accumulate, completion thresholds are reached asymmetrically. The...
