Several studies this year — some disputed — have suggested a political tilt (toward Democrats) among professors. Now a new study is being released saying that social science professors are overwhelmingly Democratic, that Democratic professors in those disciplines are more homogeneous in their thinking than are Republicans, and that Republican scholars are more likely than Democrats in the field to end up working outside of academe.

The study will appear in the journal Critical Review and its authors argue that it provides more evidence about political bias in academe. But leaders in some of the disciplines studied say that the study overstates and oversimplifies the role of party affiliation in academic life, and that the authors do not provide evidence of discrimination.

The latest study is based on surveys conducted in 2003 of members of various disciplinary associations. On the question of political affiliation, the survey found the following breakdown of Democrats to Republicans:

Anthropologists and sociologists — 21.1:1

Political and legal philosophers — 9.1:1

Historians — 8.5:1

Political scientists — 5.6:1

Economists — 2.9:1
