'The State of Intellectual Freedom in America' (Written Testimony Before the United States House of Representatives Committee on the Judiciary Subcommittee on the Constitution and Civil Justice)

Abstract

Disagreement between knowledgeable scientific experts and median political views often do not suggest political bias on the part of scientists, but rather an effort by think tanks, media organizations, interest groups and politicians to inappropriately politicize scientific issues. For example, the causes and consequences of Climate Change are scientific issues. The likely economic harm from such changes, and the costs of preventing or mitigating them, are also scientific issues. So are the adverse health consequences from air and water pollution or the health effects of smoking. So is the question of whether tax cuts can generate enough economic growth to reduce the Debt-to-GDP ratio. While scientific questions can have political and policy implications, scientific inquiry should not be politicized. The best evidence should be analyzed with the best methods, and the implications and degree of uncertainty honestly conveyed to policymakers and the public. But according to scientific experts, many scientific issues have been inappropriately politicized when scientific evidence threatened private sector profits or government budgets. These issues include the causes and effects of climate change, the health risks of pollution, and the dangers of tobacco use. According to a Pew survey, nearly 80 percent of scientists believe that previous administrations suppressed government scientists’ findings for political reasons. Many scientists worry that suppression of scientific findings for political reasons is becoming more common. Note that the Pew sample consists overwhelmingly of natural or “hard” scientists in fields such as medical sciences, chemistry, physics and geosciences. Pew’s sample included those who work in private industry as well as those who work in government and universities. Recently, there have been systematic efforts by some members of Congress to weaken the role of science in informing agency rule-making and increase the role of political actors. Some politicians have also sought to prevent government agencies from collecting basic data about demographics, the environment, health and safety, and the economy, even if de-identified to protect individual privacy. Today, threats to academic freedom can come from powerful donors, political leaders, and outside pressure groups who sometimes seek to subtly (or not so subtly) influence ostensibly neutral and unbiased academic research to further their own business interests or other political preferences. The best way to protect universities from undue influence may be to secure and expand revenue sources that are indifferent to or cannot sway the conclusions of academic research. This is analogous to the approach we take to try to protect the independence of members of the federal judiciary or the Federal Reserve.
