 Should we then focus on practices rather than on integrative theories in our interpretation of Kuhnian paradigms? The trouble with this move is that practices can also change so rapidly that it is tempting to speak of revolutionary transformations of scientific work even though there is little change in the overarching theoretical framework (see Part II of Soler et al. 2008). Moreover, as Baird (2004) points out, the rapid replacement of old practices by new is often a product of efficiency rather than intellectual incompatibility. Why continue to do gene sequencing by hand when automated processing in now available? Replacement can also be a product of change in research style, given that, as Kuhn already recognized, scientific communities are cultural communities.
