Although the introduction touches on 21st attitudes regarding intelligence in the US, Lecklider's focus is in fact on contradicting certain claims about the history of intelligence in American culture posited in the 1960s, by historians such as Richard Hofstadter, author of Anti-intellectualism in American Life. While Lecklider documents the frequent exoticization and othering of intellectuals over the decades between 1900-1960, he explores the "expansion of brainpower across class, race, and gender lines that had both informed and been shaped by popular culture" that 1960s scholars ignores. To this end, Lecklider goes decade by decade, detailing the historical context of "ordinary" people's relationship with intellectualism in the early and mid-twentith century, from the explosion of popular interest in the theory of relativity, and by extension Albert Einstein, to the budding progressive political associations throughout the 20s and 30s which ultimately led to the marginalization of intellectuals during the Red Scare, following the unsettling associations with the Manhattan Project. Though Lecklider makes interesting points, he unfortunately spends far too much time over-analyzing fictional portrayals of intellectuals during these periods, not to mention his extended discussion of New Deal promotional posters for libraries which could have been left out entirely. This is a very niche topic, and given the frequent inaccessibility of the writing, it's no surprise that this work is out of print.
