The problem of demarcation continues to attract attention, in part because solutions are perceived to have enormous social significance. The civic motivation, however, I argue is in tension with the heterogeneity of the sciences. Philosophers of science would be better employed reflecting on the features, causes, and consequences, of created, scientific controversies. These arise when relevant experts are in broad agreement about what conclusions can sensibly be drawn from available evidence, but the public perceives an expert community deeply divided and conclusions that are plagued by profound and systemic uncertainty. In the second part of the paper I explore this concept further.
