" neutral stability normally occurs only at transitions, at critical settings of a system’s parameters (the “knobs” that control its properties). But the Kuramoto model was breaking this rule. Its incoherent state was doggedly staying neutrally stable, even as we widened the bell curve to make the population more diverse. Turning that knob over a wide range of parameters made no difference. "
