Sometimes the winning move is not playing. A student of labor issues, Sarah Mason paid attention while schlepping 2,200 fares for Lyft. She found herself irrationally motivated to work extra hours — even under risky conditions — to reap rewards as simple as getting better ratings, which don’t provide extra pay, or meeting ride quotas despite diminishing bonuses. Such gamification of work environments, Mason writes, is a proven motivator. But some fellow drivers are shutting down their apps en masse to stimulate surge pricing — and gaming the algorithms right back.
