18. Views that global risks are either inevitable, depend entirely on casual factors not subject to human influence, or depend on the highest-level politicians who are unreachable

The circulation of certain ideas in a society, namely that global risks are real and it is necessary to make efforts for their prevention, can create a certain background which indirectly drives mechanisms of decision-making. Consider the process of crystallization; it requires nucleation points and certain saturation levels of a chemical in solution to get started. Unless the entire solution is supersaturated and nucleation points are provided, crystallization does not occur. Taking difficult society-wide steps like preparing for global risks is an analogous process. Every little bit of action and knowledge matters, no matter where it is distributed. Higher-ups are reluctant to take action unless they perceive there will be a certain level of understanding and approval among their subordinates. This effect becomes even more acute as one approaches the top of the pyramid. Understanding must be commonplace near the bottom and middle of the pyramid before the top does anything about it.
