Fourth, countries are poor often because of weak, inefficient, or corrupt government, characteristics that may disable them from taking cost-justified precautions. And the difficulty people everywhere have in thinking in terms of probabilities – especially low probabilities, which they tend to write off – weakens political support for incurring the costs of taking precautionary measures.
第四，穷国之所以贫穷，大多是因为其政府软弱、低效率或者腐败。这些特征使得他们无力采取成本合算的预防措施。并且加上世界各地的人们在考虑可能性时存在困难，因此就削弱了为采取预防性措施进行开销的政治支持。特别是那些较低的可能性，人们倾向于将它们一笔勾销。
