 That tendential evolution was reflected in, and perhaps amplified by, the arrival of new participants (with then current academic affiliations in parenthesis), including the political scientist Stathis Kalyvas (Yale) and the philosopher Seana Shiffrin (UCLA). Even those who identified as Marxists were less likely to think of Marxism as “a comprehensive theoretical paradigm capable of constituting a general theory of history and society” (Wright 2005a: 342).

That “most” appears to include Roemer himself:
