When we want advice from others, we often casually speak of “getting some feedback.” But how many of us give a thought to what this phrase means? The idea of feedback actually dates to World War II, when the term was developed to describe the dynamics of self-regulating systems, which correct their actions by feeding their effects back into themselves. By the early 1970s, feedback had become the governing trope for a counterculture that was reoriented and reinvigorated by ecological thinking.

The Culture of Feedback digs deep into a dazzling variety of left-of-center experiences and attitudes from this misunderstood period, bringing us a new look at the wild side of the 1970s. Belgrad shows us how ideas from systems theory were taken up by the counterculture and the environmental movement, eventually influencing a wide range of beliefs and behaviors, particularly related to the question of what is and is not intelligence. He tells the story of a generation of Americans who were struck by a newfound interest in—and respect for—plants, animals, indigenous populations, and the very sounds around them, threading his tapestry with cogent insights on environmentalism, feminism, systems theory, and psychedelics. The Culture of Feedback repaints the familiar image of the ’70s as a time of Me Generation malaise to reveal an era of revolutionary and hopeful social currents, driven by desires to radically improve—and feed back into—the systems that had come before.

After the techno-futurism of the 1950s and the utopian 1960s vision of a “great society,” the 1970s saw Americans turning to the past as a source for both nostalgic escapism and serious reflection on the nation’s history. While some popular works like Grease presented the relatively recent past as a more innocent time, far away from the nation’s post-Vietnam, post-Watergate malaise, others like Roots used America’s bicentennial as an occasion for deep soul-searching. 
 
Happy Days investigates how 1970s popular culture was obsessed with America’s past but often offered radically different interpretations of the same historical events and icons. Even the figure of the greaser, once an icon of juvenile delinquency, was made family-friendly by Henry Winkler’s Fonzie at the same time that he was being appropriated in more threatening ways by punk and gay subcultures. The cultural historian Benjamin Alpers discovers similar levels of ambivalence toward the past in 1970s neo-noir films, representations of America’s founding, and neo-slave narratives by Alex Haley and Octavia Butler. By exploring how Americans used the 1970s to construct divergent representations of their shared history, he identifies it as a pivotal moment in the nation’s ideological fracturing.
