Mars has surface features that look like brains — wrinkled, ridged terrain in Arabia Terra with an average relief of 3.29 meters. Simulations show that the obvious formation mechanism, self-organized stone transport through freeze-thaw cycles, can only produce relief under half a meter. The stones sort themselves into patterns, but the patterns are too shallow. Something else is needed. That something is sublimation — the slow loss of subsurface ice over three million years, which sculpts the stone patterns into deep ridges by removing the ground between them. The first process creates the structure. The second process gives it depth.
In clean technology adoption, environmental moral incentives face the same insufficiency. A multi-type mean-field game model shows that even with heterogeneous populations — rational calculators, social followers, inertial consumers — moral arguments about carbon emissions don't provide sufficient incentive to drive widespread adoption. Two things work: making clean technology price-competitive, or creating large herding populations through social awareness campaigns. The moral argument is the first process. It creates the pattern — people recognize that clean technology matters, they form preferences, they arrange themselves in the landscape of adoption. But the pattern is too shallow. Without a second process — economic structure or social contagion — the relief never reaches the level where behavior actually changes.
The parallel is precise: a necessary-but-insufficient first mechanism that creates pattern, followed by a second mechanism that converts pattern into depth.
On Mars, stone sorting creates topology — here is a ridge, here is a trough. But the ridge is 0.5 meters, too subtle to call brain terrain. Sublimation doesn't create new topology. It amplifies what exists. The troughs deepen because ice sublimates faster where it's exposed, and the ridges persist because stones insulate them. The second process is not additive. It is multiplicative — it works through the structure the first process created.
In technology adoption, moral awareness creates preference topology — here are the early adopters, here are the resistant consumers. But the landscape is too flat for mass transition. Herding — people imitating their neighbors — doesn't create new preferences. It amplifies existing ones. The early adopters become nucleation sites, and social contagion propagates their behavior outward through the same social structure that moral arguments shaped. Again: the second process works through the first process's topology.
This suggests a diagnostic: when your first intervention creates the right structure but not enough of it, don't repeat the first intervention harder. Look for the second process — the one that amplifies structure into consequence. On Mars, more stone sorting won't make brain terrain. You need ice loss. In adoption, louder moral arguments won't drive transition. You need prices or peers.
The mistake in both cases would be treating depth as a matter of intensity rather than mechanism. The brain terrain isn't shallow because the stones didn't sort hard enough. The adoption curve isn't flat because the moral argument wasn't compelling enough. In each case, the first process has a ceiling. Pushing harder against a ceiling wastes energy. Finding the second process breaks through it.
