I read this deck today, about “Gen Z” - i.e. teenagers. Obviously generations are something of a bugbear of mine, and this deck does all the usual generation-thinking things: goes overboard on distinctions, worships attitudinal data, fails to cross-analyse by other demographic groups, etc etc.
But it’s also an example of a problem that spreads well-beyond generation-level thinking. The problem is stacking - taking multiple separate quantitative studies and using them to tell a story about a particular group - not just generations, but ‘men’, ‘women’, ‘the rich’, ‘the emerging middle class’, and more.
