Features: Indeed, all countries strive to reduce risks, enhance safety, and extend life expectancy. Reducing risks has become a fundamental goal of modern governments. How should global warming be addressed? How do countries manage the risks of terrorism, chemical weapons, and aircraft safety? Should governments regulate or ban genetically modified foods? Should arsenic be removed from drinking water? What is the relationship between energy policies and environmental protection? Should governments mandate fuel efficiency standards for vehicles? Would such requirements reduce vehicle safety? These questions trouble public institutions both domestically and internationally. However, most of the time, government actions are blind. They often waste resources on minor issues rather than urgent ones. Sometimes, they yield to short-sighted public opinion. At times, they fail to consider the negative consequences of their measures. Sometimes, they even worsen the situation. In regulating risks, they incur high costs, which create new risks, including price increases, wage declines, unemployment, and even illness and death. Countries do not place enough emphasis on science. They tend to act on intuition or temporary fears rather than investigate the facts. Leaders in countries facing immense disasters brought by technology or terrorism must confront this dilemma. This is also the era when environmental quality and worker health have become serious public issues. This book first attempts to link people's habitual thinking about risks to the frequent problems in the political and legal fields. As we will see, people often know very little about dangers. Sometimes they overreact. Their mistakes are fatal. These mistakes lead to various troubles in daily life, including illness and death. The same mistakes cause problems in policies and laws, which is the main focus of this book. When people panic, governments are likely to take action, even if the panic is unfounded. When people are indifferent, governments are likely to be negligent, even when serious risks actually exist. We will see that a more sensitive risk prevention mechanism can save thousands of lives and billions of dollars. Additionally, I am happy to propose a direct and simple approach to address the issues listed here: Before taking action, if feasible, governments should conduct cost-benefit analyses, meticulously calculating the consequences of different actions. Cost-benefit analysis helps people understand the difficulty of the problems they face. It requires studying the costs of mitigating the problem and explaining who will bear these costs. It requires valuing science and ensuring that experts or technical officials play a significant role in shaping government policies. The cost-benefit method I advocate has only recently emerged and still requires appropriate justification. I use cost-benefit analysis not primarily for economic reasons but mainly because it corrects cognitive limitations and responds to public demands. Some people view cost-benefit analysis as a cold, inhumane calculation that treats life as a commodity and assumes that the government is a massive machine maximizing efficiency. Conversely, I believe cost-benefit analysis should be seen as a simple and practical tool designed to better assess the consequences of regulatory measures. Governments using cost-benefit analysis have the right to determine who has been helped and who has been harmed. For example, it may convince people that special measures must be taken to protect children, the poor, or members of minority groups. Governments using cost-benefit analysis should also strive to accurately describe the various impacts of regulatory measures. It must be understood correctly that cost-benefit analysis is not metaphysics. Instead, it benefits both governments and the public by ensuring that regulatory measures effectively achieve their goals. For instance, if a proposed economic fuel efficiency standard significantly reduces greenhouse gas emissions but also makes cars smaller and less safe, leading to thousands of annual deaths, officials and the public should clearly recognize this negative fact. However, merely requiring governments to conduct detailed analyses of risks and their regulation is not enough. I advocate overcoming the problems listed above through institutional reforms of government departments. Congress should take measures to ensure that the risk regulation system has a comprehensive meaning. Regulatory agencies should be authorized to reject measures when the regulation itself will create significant new risks. Executive agencies should create public websites to provide information on existing risks, enabling people to compare different risks. When regulation worsens the situation, courts should prohibit governments from taking action. Most importantly, I propose that governments should use "sensitive tools" (i.e., cost-benefit analysis), which can effectively reduce risks without incurring high costs or overburdening the government, and will provide us with more protection than expected. Several highly sensitive tools go beyond government-level cost-benefit analysis by leveraging market forces, as markets are far more effective at concentrating information than government officials. Thus, I will explore how economic incentives, risk control contracts, and "free-market environmentalism" can avoid the problems associated with centralized risk control. The main advantages of cost-benefit analysis lie in its ability to identify protective measures for health and longevity that are often overlooked by intuition. Striving to transcend intuition and understand the consequences of one's choices cannot be seen as reducing social goals to a mathematical formula. Instead, it is a method of recognizing human limitations and promoting laws and policies that align with human objectives.
