"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
Lippmann is describing a mental shortcut that still runs the internet on fumes: we don’t form judgments from a wide view of reality, we grab a convenient anecdote and appoint it “proof.” The sting is in “casual mind.” He’s not talking about stupidity so much as laziness-as-default, the everyday attention span that wants a verdict faster than it wants accuracy. “Pick out or stumble upon” neatly captures how bias works both actively and passively: sometimes we hunt for confirming evidence; sometimes the world hands us a vivid outlier and we treat it like the norm because it’s memorable, not representative.
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.
