Free market fundamentalism was the ideology that held together the alliance of military, political, corporate, and scientific leaders who spearheaded the U.S.’s effort in the Cold War. Scientists like Lee and Singer, who came to prominence as part of this alliance, naturally carried their worldview with them into the next phase of their lives after the Cold War ended. Yet, without the threat of brutal, authoritarian communism on the horizon, free market fundamentalism was no longer a useful political strategy. Instead, it gave way to serious misconceptions about history and paranoid conspiracy theories about the government—and, eventually, science itself.
