Second, to the extent that effective precautions require governmental action, the fact that government is a centralized system of control makes it difficult for officials to respond to the full spectrum of possible risks against which cost-justified measures might be taken. Given the variety of matters to which they must attend, officials are likely to have a high threshold of attention below which risks are ignored.
第二，由于有效的预防措施要求采取政府行动，政府作为一个集权的控制体系使得官员难以应付全部可能的风险。否则，就有可能采取措施，其成本受到控制从而变得合理。鉴于官员们应付的事情繁杂，他们对于关注就有一个比较高的门槛标准，低于标准以下的风险就被忽略不计了。
