This came up on the thread on WUSTL, and I thought it was an interesting topic to ponder. Though "in a time of transition" is vague, it was originally brought up in the context of a substantial change that creates an opening that an enterprising young department can exploit, so I leave that as the going definition.
Points against us being in transition:
1) There do not appear to be major insurgent theories upending how we think of the social world. Sure there are some big ideas coming out here and there (e.g., field theory as a unifying lens on orgs and social movements), but there is no indication that any of these are about to upend the discipline just yet.
2) There also appears to be no major challenge brewing to the epistemic foundations of the discipline, especially as compared to the 1970s-1990s. The various radical sociologies have been around for a few decades and are familiar old news by now. With their radical journals, radical ASA sections, etc., they are a cottage industry rather than an insurgent movement. It seems exceptionally unlikely that they could bring about major epistemic change, and I am not sure anyone else is trying.
But then there are things that suggest that we may indeed be in transition:
1) The internet may yet bring major to how we do research, or at least quantitative research. It seems almost certain to displace lots of our previous data sources over time. I would imagine most grad intro quant methods classes will soon feature at least some basic programming. So perhaps the methods part of the discipline may yet see a major shakeup, as statistical sociology and computational sociology tango behind the scenes.
2) There may be a higher-than-normal generational shift in the discipline right now, as baby boomers retire and free up spots for younger scholars. Demographers, any comments on whether this is happening? If it is, the cohort effects may yet change what kind of work is valued by various departments, and so could perhaps shift the feel of the market quite a bit. But this is all speculation.
So I think my final vote is for "maybe-sort-of."
What are your thoughts, y'all?
