As the French historian Pierre Nora wrote in 1996, the careful analyst trying to talk about generations will always struggle: ‘The generational concept would make a wonderfully precise instrument if only its precision didn’t make it impossible to apply to the unclassifiable disorder of reality.’ The problem with transferring historical and sociological ways of thinking about generational change into the public sphere is that ‘unclassifiability’ is both terrifying and boring. Big, sweeping explanations of social change sell. Little, careful studies of same-age cohorts, hemmed in on all sides by rich specificity, do not.
Perhaps the pseudoscientific use of supposed ‘generations’ would irk less if it weren’t so often used to demean the young. Millennials, consultants advise prospective employers, feel entitled to good treatment even in entry-level jobs, because they’ve been overpraised their whole lives. Millennials won’t buckle down and buy cars or houses, economists complain; millennials are lurking in their parents’ basements, The New Yorker cartoon stereotype runs, tweeting and texting and posting selfies and avoiding responsibility.
