A. F. Bentley's The Process of Government (1908) is widely accepted as an i
mportant source of contemporary interest group study. This paper argues to
the contrary that Bentley's arguments in this area are obscure and have con
tributed little to the programme of modern interest group research. His imp
ortance is as a contributor to the debate on the nature of social science a
nd social science method and not as the starting-point for interest group a
nalysis. The judgement about his role as a social scientist should rest on
consideration of his body of work and not simply the one book. In terms of
his much cited book, Bentley, it is argued, is misread. The central purpose
of this article is to explore the consequences of that misinterpretation.
The misreading of The Process of Government, and the unmerited assumption t
hat it is directly connected to modern interest group theory, has led to a
misunderstanding of that contemporary theory. In particular his use of the
term 'group' is much wider in scope than is now usually followed. This mean
s that his claims are not so uni-dimensional as they appear when extracted
from their context. Bentley used the term in a sociological sense that incl
uded informal social associations as 'groups': these are not the sort of fo
rmal, collective organizations of the interest group type as identified in
political science.
It is argued that the major sources of ideas current in the interest group
field are Truman (1951) and the case-study authors of the 1930s such as Ode
gard, Childs, Herring and Schattschneider, Bentley's contribution to politi
cal science is not as progenitor of interest group studies, but his emphasi
s on process anticipates the policy studies movement.
