The Death of Truth. Michiko Kakutani

feathers together, hoping for a duck.” In fact, the Iraq war would prove to be one of the young century’s most catastrophic events, exploding the geopolitics of the region and giving birth to ISIS and a still unspooling set of disasters for the people of Iraq, the region, and the world.

      ALTHOUGH TRUMP frequently criticized the decision to invade Iraq during the 2016 campaign, his White House has learned nothing from the Bush administration’s handling of that unnecessary and tragic war. Instead, it has doubled down on reverse-engineered policy making and the repudiation of experts.

      For instance, the State Department has been hollowed out as a result of Steve Bannon’s vow to fight for the “deconstruction of the administrative state” and the White House’s suspicion of “deep state” professionals. The president’s son-in-law, Jared Kushner, a thirty-six-year-old real-estate developer with no government experience, was handed the Middle East portfolio, while the shrinking State Department was increasingly sidelined. Many important positions stood unfilled at the end of Trump’s first year in office. This was partly because of downsizing and dereliction of duty, partly because of a reluctance to appoint diplomats who expressed reservations about the president’s policies (as in the case of the crucial role of ambassador to South Korea), and partly because of the exodus of foreign service talent from an agency that, under new management, no longer valued their skills at diplomacy, policy knowledge, or experience in far-flung regions of the world. Combined with Trump’s subversion of longtime alliances and trade accords and his steady undermining of democratic ideals, the carelessness with which his administration treated foreign policy led to world confidence in U.S. leadership plummeting in 2017 to a new low of 30 percent (below China and just above Russia), according to a Gallup poll.

      In some respects, the Trump White House’s disdain for expertise and experience reflected larger attitudes percolating through American society. In his 2007 book, The Cult of the Amateur, the Silicon Valley entrepreneur Andrew Keen warned that the internet not only had democratized information beyond people’s wildest imaginings but also was replacing genuine knowledge with “the wisdom of the crowd,” dangerously blurring the lines between fact and opinion, informed argument and blustering speculation.

      A decade later, the scholar Tom Nichols wrote in The Death of Expertise that a willful hostility toward established knowledge had emerged on both the right and the left, with people aggressively arguing that “every opinion on any matter is as good as every other.” Ignorance now was fashionable.

      “If citizens do not bother to gain basic literacy in the issues that affect their lives,” Nichols wrote, “they abdicate control over those issues whether they like it or not. And when voters lose control of these important decisions, they risk the hijacking of their democracy by ignorant demagogues, or the more quiet and gradual decay of their democratic institutions into authoritarian technocracy.”

      THE TRUMP White House’s preference for loyalty and ideological lockstep over knowledge is on display throughout the administration. Unqualified judges and agency heads were appointed because of cronyism, political connections, or a determination to undercut agencies that stood in the way of Trump’s massive deregulatory plans benefiting the fossil fuel industry and wealthy corporate donors. Rick Perry, who was famous for wanting to abolish the Department of Energy, was named to head it, presiding over cutbacks to renewable energy programs; and the new EPA head, Scott Pruitt, who had repeatedly sued the Environmental Protection Agency over the years, swiftly began dismantling and slow walking legislation designed to protect the environment.

      The public—which opposed the GOP tax bill and worried that its health care would be taken away—was high-handedly ignored when its views failed to accord with Trump administration objectives or those of the Republican Congress. And when experts in a given field—like climate change, fiscal policy, or national security—raised inconvenient questions, they were sidelined, or worse. This, for instance, is what happened to the Congressional Budget Office (created decades ago as an independent, nonpartisan provider of cost estimates for legislation) when it reported that a proposed GOP health-care bill would leave millions more uninsured. Republicans began attacking the agency—not just its report, but its very existence. Trump’s director of the Office of Management and Budget, Mick Mulvaney, asked whether the CBO’s time had “come and gone,” and other Republicans proposed slashing its budget and cutting its staff of 235 by 89 employees.

      For that matter, the normal machinery of policy making—and the normal process of analysis and review—were routinely circumvented by the Trump administration, which violated such norms with knee-jerk predictability. Many moves were the irrational result of a kind of reverse engineering: deciding on an outcome the White House or the Republican Congress wanted, then trying to come up with rationales or selling points afterward. This was the very opposite of the scientific method, whereby data is systematically gathered and assessed to formulate and test hypotheses—a method the administration clearly had contempt for, given its orders to CDC analysts to avoid using the terms “science-based” and “evidence-based.” And it was a reminder that in Orwell’s dystopia in 1984 there is no word for “science,” because “the empirical method of thought, on which all the scientific achievements of the past were founded,” represents an objective reality that threatens the power of Big Brother to determine what truth is.

      In addition to announcing that it was withdrawing from the Paris climate accord (after Syria signed on, the United States was left as the lone country repudiating the global agreement), the Trump administration vowed to terminate President Obama’s Clean Power Plan and reverse a ban on offshore oil and gas drilling. Scientists were dismissed from government advisory boards, and plans were made to cut funding for an array of research programs in such fields as biomedicine, environmental science, engineering, and data analysis. The EPA alone was facing proposed cuts from the White House of $2.5 billion from its annual budget—a reduction of more than 23 percent.

      IN APRIL 2017, the March for Science, organized in Washington to protest the Trump administration’s antiscience policies, grew into more than four hundred marches in more than thirty-five nations, participants marching out of solidarity with colleagues in the United States and also out of concern for the status of science and reason in their own countries. Decisions made by the U.S. government about climate change and other global problems, after all, have a domino effect around the world—affecting joint enterprises and collaborative research, as well as efforts to find international solutions to crises affecting the planet.

      British scientists worry about how Brexit will affect universities and research institutions in the U.K. and the ability of British students to study in Europe. Scientists in countries from Australia to Germany to Mexico worry about the spread of attitudes devaluing science, evidence, and peer review. And doctors in Latin America and Africa worry that fake news about Zika and Ebola are spreading misinformation and fear.

      Mike MacFerrin, a graduate student in glaciology working in Kangerlussuaq, a town of five hundred in Greenland, told Science magazine that the residents there had practical reasons to worry about climate change because runoff from the ice sheet had partially washed out a local bridge. “I liken the attacks on science to turning off
