Think of a research problem of interest to you. In 2500 words or less,
critically compare and contrast the implications three of the following
quotations have for theory and empirical research design regarding that
problem. Which approaches are more appropriate, and which less? Can
strengths of various approaches be combined usefully? Note that quotes that
are grouped together do not always agree with one another. As part of your
discussion you should address the most important and relevant of such
differences.
- ``An explanation is an adequate description of underlying causes
helping to bring about the phenomenon to be explained.'' (Miller 1987, 60).
``Scientists and philosophers of science want to know when a given set of
propositions, if true, explain why something happened. They also want to know
when a given body of data confirm a proposition, a proposition which might,
then, be used to explain. The answer to the second question that I will be
developing is causal, comparative and historical. Confirmation, I will argue,
is the fair causal comparison of a hypothesis with its current rivals''
(Miller 1987, 155). ``Varying degrees of `confirmation' are conferred upon a
theory through the number of plausible rival hypotheses available to
account for the data. The fewer such plausible rival hypotheses remaining,
the greater the degree of `confirmation''' (Campbell and Stanley 1966, 36).
- ``As interworked systems of construable signs (what, ignoring
provincial usages, I would call symbols), culture is not a power, something to
which social events, behaviors, institutions, or processes can be causally
attributed; it is a context, something within which they can be
intelligibly--that is, thickly--described'' (Geertz 1973, 14). ``There is
no reason why the conceptual structure of a cultural interpretation should be
any less formulable, and thus less susceptible to explicit canons of
appraisal, than that of, say, a biological observation or a physical
experiment--no reason except that the terms in which such formulations can be
cast are, if not wholly nonexistent, very nearly so. We are reduced to
insinuating theories because we lack the power to state them'' (Geertz 1973,
24). ``Theoretical ideas are not created wholly anew in each study; as I
have said, they are adopted from other, related studies, and, refined in the
process, applied to new interpretive problems'' (Geertz 1973, 27).
- ``We do not wish to suggest that quantitative empirical research is of
minor importance for the sociological enterprise. Quite the contrary:
Quantitative research is essential both for descriptive purposes and for
testing sociological theories. We do, however, believe that many sociologists
have had all too much faith in statistical analysis as a tool for
generating theories, and that the belief in an isomorphism between
statistical and theoretical models, which appears to be an integral feature of
the causal-modeling approach, has hampered the development of sociological
theories built upon concrete explanatory mechanisms'' (Hedström and
Swedborg 1998, 17). ``The distinctive feature of a mechanism is not that it
can be universally applied to predict and control social events, but that it
embodies a causal chain that is sufficiently general and precise to enable us
to locate it in widely different settings. It is less than a theory, but a
great deal more than a description, since it can serve as a model for
understanding other cases not yet encountered'' (Elster 1993, 5).
- ``I would now like to turn to the fundamental assumption of the revealed
preference approach, viz., that people do reveal their underlying preferences
through their actual choices. Is this a reasonable presumption?'' (Sen 1997,
60). ``Many issues remain unresolved, including the empirical importance of
commitment as a part of behaviour, which would vary, as I have argued, from
field to field. I have also indicated why the empirical evidence for this
cannot be sought in the mere observation of actual choices, and must involve
other sources of information, including introspection and discussion. There
remains, however, the issue as to whether this view of man amounts to seeing
him as an irrational creature. Much depends on the concept of rationality
used, and many alternative characterizations exist. In the sense of
consistency of choice, there is no reason to think that admitting
commitment must imply any departure from rationality. This is, however, a
weak sense of rationality'' (Sen 1997, 104). ``My approach incorporates
experiences and social forces into preferences or tastes through two basic
capital stocks. Personal capital, P, includes the relevant past
consumption and other personal experiences that affect current and future
utilities. Social capital, S, incorporates the influence of past
action by peers and others in an individual's social network and control
system (Becker 1996, 4).
- ``To generalize about social revolutions, to develop explanations of
their causes and outcomes, one can employ comparative historical analysis with
selected slices of national historical trajectories as the units of
comparison.... There are two main ways to proceed. First, one can try to
establish that several cases having in common the phenomenon one is trying to
explain also have in common a set of causal factors, although they vary in
other ways that might have seemed causally relevant. This is what Mill called
the `Method of Agreement.' Second, one can contrast the cases in which the
phenomenon to be explained and the hypothesized causes are present to other
cases in which the phenomenon and the causes are both absent, but which are
otherwise as similar as possible to the positive cases. This procedure Mill
labeled the `Method of Difference.' ... In practice, though, it is often
possible, and certainly desirable, to combine these two comparative logics.
This is done by using at once several positive cases along with suitable
negative cases as contrasts'' (Skocpol 1979, 35-37). ``Apparent causes that
all the selected cases have in common may turn out to be just as common among
cases in which the effect they were supposed to have caused has not occurred.
Relationships that seem to exist between causes and effects in a small sample
selected on the dependent variable may disappear or be reversed in a sample
uncorrelated with the position on the dependent variable'' (Geddes 1991, 149).
- ``Good experimental design is separable from the use of statistical
tests of significance. It is the art of achieving interpretable comparisons
and as such would be required even if the end product were to be graphed
percentages, parallel prose case studies, photographs of groups in action,
etc. In all such cases, the interpretability of the `results' depends upon
control over the factors we have been describing. If the comparison is
interpretable, then statistical tests of significance come in for the decision
as to whether or not the obtained difference rises above the fluctuations to
be expected in cases of no true difference for samples of that size. Use of
significance tests presumes but does not prove or supply the comparability of
the comparison groups or the interpretability of the difference found''
(Campbell and Stanley 1966, 22). ``In everyday life, three possible decisions
about causal effects are available. They may be strong, weak, or simply
undecidable. Traditional significance testing as practised in the social
sciences has the peculiar feature that it groups all effects into just two
classes--present and absent. Not only does it fail to differentiate the
important from the trivial; it also takes no account of uncertainty'' (Achen
1982, 46).
