Mixing science and politics
❝❝And that brings us to the second great threat from the Left: its long tradition of mixing science and politics. To conservatives, the fundamental problem with the Left is what Friedrich Hayek called the fatal conceit: the delusion that experts are wise enough to redesign society. Conservatives distrust central planners, preferring to rely on traditional institutions that protect individuals’ “natural rights” against the power of the state. Leftists have much more confidence in experts and the state. Engels argued for “scientific socialism,” a redesign of society supposedly based on the scientific method. Communist intellectuals planned to mold the New Soviet Man. Progressives yearned for a society guided by impartial agencies unconstrained by old-fashioned politics and religion. Herbert Croly, founder of the New Republic and a leading light of progressivism, predicted that a “better future would derive from the beneficent activities of expert social engineers who would bring to the service of social ideals all the technical resources which research could discover.”
This was all very flattering to scientists, one reason that so many of them leaned left. The Right cited scientific work when useful, but it didn’t enlist science to remake society—it still preferred guidance from traditional moralists and clerics. The Left saw scientists as the new high priests, offering them prestige, money, and power. The power too often corrupted. Over and over, scientists yielded to the temptation to exaggerate their expertise and moral authority, sometimes for horrendous purposes.
Drawing on research into genetics and animal breeding from scientists at Harvard, Yale, Johns Hopkins, and other leading universities, the eugenics movement of the 1920s made plans for improving the human population. Professors taught eugenics to their students and worked with Croly and other progressives eager to breed a smarter society, including Theodore Roosevelt, Woodrow Wilson, and Margaret Sanger. Eventually, other scientists—notably, in England—exposed the shoddy research and assumptions of the eugenicists, but not before the involuntary sterilization or castration of more than 35,000 Americans. Even after Hitler used eugenics to justify killing millions, the Left didn’t lose its interest in controlling human breeding.❞❞
