"The tendency of the casual mind is to pick out or stumble upon a sample which supports or defies its prejudices, and then to make it the representative of a whole class"
About this Quote
The subtext is a quiet indictment of democratic public opinion. Lippmann spent his career worrying about how mass media, slogans, and simplified “pictures in our heads” replace direct knowledge. This line exposes the mechanism: once you can be moved by a sample, you can be managed by whoever supplies the sample. It’s not just that we stereotype; it’s that our stereotypes are fueled by a system that traffics in the punchiest case, the most shareable exception, the clip that flatters what we already think.
Context matters: writing in the early 20th century, Lippmann watched propaganda mature, newspapers become industrial-scale, and public life grow too complex for any citizen to personally verify. His warning lands now because “a sample” has become a feed: a constant stream of curated micro-evidence that can “support or defy” prejudices on demand. The line doesn’t ask us to stop having opinions. It dares us to earn them.
