Title: On scientific method
1On scientific method
Presentation 7 Environment and Sustainable
Development course UNU-MERIT PhD programme
2What is science?
- It is what scientists do reading, researching,
writing, talking to each other, create clubs - It is the process of hypothesis formation,
empirical testing, hypothesis reformulation,
retesting, and so on - Falsification or verification?
3Hypotheses of Adeoti
- H1a The introduction of the S.I.8/S.I.9
environmental regulatory law has led to increased
adoption of wastewater treatment plants in the
Nigerian manufacturing industry. - H2a The adoption of EBT will be positively
correlated with the firms internal capability
for innovation as defined by the share of
technical personnel in the total employment. - H2b The adoption of EBT may be related to the
existing level of investment in capital equipment
for the main production activities. - H2c The capability of a firm to adopt an EBT
will be inherently determined by the
technological knowledge related network contacts
a firm has. - H2f The type of EBT adopted for compliance with
the S.I.8/S.I.9 regulation depends on the
strategy for environmental policy implementation,
whether co-operative or antagonistic.
4Questions of transitions project
- Q1 Are there identifiable transition phases such
as the predevelopment stage, take-off stage,
breakthrough stage and stabilisation stage? Can
such stages be operationalised? - Q2 To what extent were TT foreseen, expected and
intentionally managed, at the different stages?
What was the role of widely shared expectations? - Q3 Are there common strategic behavioural
patterns in transitions (such as regime actors
first fighting a new development pioneered by
niche actors and later on sustaining it)? - Q4 What role did incremental innovation play in
TT? Did it help to sustain the old regime
(sailing ship effect) by defending it against a
new development or did it provide opportunities
for further change (stepping stone dynamic)? - Q5 Does the interplay of technical change and
institutional change differ in different
transitions and in various phases of a particular
transition? Does technical change lead/precede
institutional change or is it the other way
round? - Q6 What was the role of public authorities (in
different phases)? What do the transitions tell
about the proper role of public authorities and
public policy in various transition stages?
5What characterises social science?
- A world that is infinitely complex
- In which people are suspended in webs of
significance (Geertz) - reflective thought precedes science which merely
employs it more methodologically. Man cannot live
among things without forming ideas about them
Because these notions are closer to us than the
realities to which they correspond, we naturally
tend to substitute them for the realities,
concentrating our speculations upon them
(Durkheim)
6Theoretical frameworks are not falsified but
accepted as the basis for research
- If you are a neoclassical economists you do not
seek to falsify the neoclassical framework of
rational actors, you work with it - Are theories falsified? Some are, others are not.
- Theories are appraised in the light of
conflicting evidence (an example is the theory of
Boserup about population pressure facilitating
technological change) - Theories may be true (valid) in certain
circumstances
7Relativist position
- Every interpretation attempts to attain clarity
and certainty, but no matter how clear an
interpretation as such appears, it cannot on this
account claim to be the causally valid
interpretation. On this level it must remain only
a peculiarly plausible hypothesis (Weber)
8The role of theory
- It offers a perspective (a theoretical lens) on
social worlds which involves categories and
certain ontological assumptions - Which may be used for offering explanation using
certain research methods and causal schemes - It facilitates communication between researchers
using the same theory and even between those that
alternative theories
9Social science questions and the answers to them
- Why is the Netherlands more rich than India is?
Is it because of natural resource endowments,
religion, culture, or because of all things
together, including contingencies the importance
of which cannot be determined in a definitive way - Why did the plain crash? Because of the weather
conditions, the engine being faulty, the pilot
doing faulty things did the engine not work
properly because of bad design or because of bad
servicing who is to blame for bad servicing, the
person doing the servicing or the procedures why
were the procedures inappropriate, is it because
the issue was not given proper attention by the
company, something made possible by the lack of
inspection by the government (why was that?)
10Causal variables within different social science
approaches of innovation
Actor network Actors, artifacts and alignment (3-As)
Regime approaches Rules, roles, regulations, and routines (4-Rs)
Social constructivism Social actors, social meaning, sociotechnical closure (3 Ss)
Political science Policy science Ideology, interests and influence (power) (3 Is) Problems, policy belief systems, policies programmes, and politics (4 Ps)
Economics Incentives and choice
11Intentionalist and monocausal explanations are
inappropriate for system innovation and societal
change The interplay of factors is important
(cause-effect chains)We may not have the 2nd
world war without Hitler but as an explanation
this is poor and teaches no lessons
12Quantitative versus qualitative methods
- Quantitative approaches relying on statistical
significance - Qualitative approaches relying on interpretative
understanding (verstehen) narrative method
(story telling)
13Source Spicer (2004)
14Synergies
- Quantitative methods may help to test whether
certain findings apply wider - Qualitative research may help to interpret odd
findings of quantitative research or qualify the
findings - Qualitative research may generate hypotheses
- The robustness of quantitative findings can be
assessed - When it comes to policy advice, contextual
aspects may be considered without getting
bewildered by sheer complexity

16Phronesis
- Aristotle distinguishes between two intellectual
virtues sophia and phronesis. Sophia (usually
translated "wisdom") is the ability to think well
about the nature of the world, and is used in our
attempts to discover why the world is the way it
is (this is sometimes equated with science)
sophia involves deliberation concerning universal
truths - Phronesis is the ability to think about how and
why we should act in order to change things, and
especially to change our lives for the better - Phronesis is about practical wisdom/judgement
routed in experience
17- Phronesis is concerned with particulars, because
it is concerned with how to act in particular
situations. One can learn the principles of
action, but applying them in the real world, in
situations which one could not have foreseen,
requires experience of the world - The importance of phronesis to contemporary
thought has been spelled out by Bent Flyvbjerg in
his book Making Social Science Matter Why Social
Inquiry Fails and How it Can Succeed Again
Flyvbjerg argues that instead of trying to
emulate the natural sciences, social science
should be practiced as phronesis
18- Phronetic social science focuses on four
value-rational questions, which are answered for
specific cases of social action (1) Where are we
going? (2) Who gains and who loses, by which
mechanisms of power? (3) Is this development
desirable? (4) What should we do about it?
Flyvbjerg (2001)
19Detached analysis or engagement with practioners?
- Essentially, all models are wrong, but some are
useful George E.P. Box - Abstract analysis of institutional arrangements
that would be optimal in idealized situations
is at best a useful heuristic for the main work,
and at worst a diversion from it Nelson and
Winter (1982)
20Schumpeter on method
- What distinguishes the 'scientific' economist
from all the other people who think, talk, and
write about economic topics is a command of
techniques that we class under three heads
history, statistics, and 'theory'. The three
together make up what we shall call Economic
Analysis. Of these three fundamental fields,
economic history -- which issues into and
includes present day facts -- is by far the most
important. I wish to state right now that if,
starting my work in economics afresh, I were told
that I could study only one of the three but have
my choice, it would economic history that I would
choose. And this on three grounds. (1) First
the subject matter of economics is essentially a
unique process in historic time. Nobody can hope
to understand the economic phenomena of any
epoch, who has not an adequate command of
historical facts and an adequate amount of
historical sense () - (2) Second, the historical report cannot be
purely economic but must inevitably reflect also
'institutional' facts that are not purely
economic () - (3) Third, it is, I believe, the fact that most
of the fundamental errors currently committed in
economic analysis are due to a lack of historical
experience more often than to any other
shortcoming of the economist's equipment.

21Pointers about PhD research
- Why do you want to do this research? (is it
really what you want to be working on for 3
years, does it fit with your research
capability?) - What do you expect to find?
- What framework (theoretical lens) do you use (and
why do you use this) - What other frameworks are there? Is your
framework better or simply more convenient for
you?
22Pointers -- continued
- The problem definition should be as specific as
possible - Engage in multi-method analysis (or make use of
the findings of others) - case studies are useful in their own right but
also help to generate hypotheses and interpret
research findings obtained with different
methods they may be used for analytical
generalisation - Econometric studies allow for statistical
generalisation - Models are rigorous
23On interpretation
- Determine the mileage of different explanations
(can it be explained in power terms, knowledge
terms, in terms of economic variables? - Determine the robustness of your results
- Acknowledge inconsistencies (instead of hiding
them)
24Presenting your results
- What have you learned?
- Did you find what you expected to find?
- How do your results compare to those of the
literature? - Are the others wrong? How solid are your results?
- What is your original contribution? This should
be clearly and explicitly stated
