  Programmes and schools
  The sociology of scientific knowledge in its Anglophone versions emerged in the 1970s in self-conscious opposition to the sociology of science associated with the American Robert K. Merton, generally considered one of the seminal authors in the sociology of science.  Merton's was a kind of "sociology of scientists," which left the cognitive content of science out of sociological account; SSK by contrast aimed at providing sociological explanations of scientific ideas themselves, taking its lead from aspects of the work of Ludwik Fleck, Thomas S. Kuhn, but especially from established traditions in cultural anthropology (Durkheim, Mauss) as well as the late Wittgenstein. David Bloor, one of SSK's early champions, has contrasted the so-called 'weak programme' (or 'program'—either spelling is used) which merely gives social explanations for erroneous beliefs, with what he called the 'strong programme', which considers sociological factors as influencing all beliefs.
