Critical Realism
School of Research
Q1: What are traditional schools of research (Research Paradigms)?
1 - Positivism (it is called
also traditional school of science or the hypothesis school)
2 - Interpretivism (It is called
also constructionism)
|
Positivism
|
Interpretivism (Constructionism)
|
Description in brief
|
After discovering a research gap,
hypotheses are formulated then tested statistically.
|
Problem is not well defined, so
you go to the people to understand the problem in qualitative way
(non-numerical way).
|
Suitable for
|
· A worldwide problem or industry
specific problem.
· Researcher has knowledge about
the top so that he could construct the
questionnaire in an efficient way
· Problem in general is not new and
literature is available for it. Therefore, there is no need for exploring the
problem.
|
· It is a firm or group of firms’
problem.
· Researcher does not know a lot
about the top so that it is preferred to observe and conduct interviews.
· Literature is not extensive in
the topic.
|
Strengths
|
· Validation is very objective because
the researcher does not intervene in the results.
· Statistics can discover
unnoticeable behaviors or relationships between concepts.
|
· Enables the researcher to be
expert in the topic because he/she touches the problem by his/her hand.
· Organizations problems are solved
and documented.
· It has a direct impact on the
economy
· It is suitable for developing
tools, software, and methodologies
|
Weakness
|
· It is not suitable for
explanatory research.
· It is not suitable for developing
tools, software, and methodologies.
|
· Validation is questioned since
the validation is conducted by taking opinions of experts (Which may be your
friends!!!!) or opinions of academics (which also your friends).
· There is no objective way for
validating your tool, software, or methodology.

Q2: A question for MIS researcher and Operations Management Researcher,
do you think developing a tool or software make you deserve to obtain PhD?
(Professor Stephen Evans, Cambridge University)
The answer is no
because you have to have a theory for awarding the PhD.
Q3: So, why do I need to develop a tool or software at the end of my
PhD?
Because your
sponsor organization sponsors you to develop a tool or software for solving the
problem.
Q4: I do not have sponsor, do you think I need to develop a tool?
Yes, because at
the end of your PhD you need to deliver to your community something tangible
otherwise your PhD may be useless.
Q5: Okay, so I will develop a tool (to delivery something tangible) and
I will develop a theory for awarding PhD. But what is the relationship between
theory and the tool?
Since you are PhD
student, you have to develop your theory to be the scientific base for
developing your tool.
Q6: Now, the most important question, which research methodologies I
should follow positivism or Interpretivism?
Actually, neither
positivism nor Interpretivism
could be followed.
Q7: Why?
Positivism alone will enable you to develop a very
good theory based on testing hypotheses (positivism
epistemology) but it will not enable you to develop your tool or software.
Moreover, it will not enable you to understand the context of the problem
(anti-positivism ontology).
On the other
hand, Interpretivism alone will enable you
to understand the problem and the context. But it will not enable you to verify
your theory in an objective way since you will validate it in a so wired way
which is asking your friends (we call them in the research experts and
academia) to tell their opinions about my model?? Certainly, they will say “it
is a big wow model”.
It is not only
the problem of validation but developing theory in an inductive way (develop
theory based on 3 or 4 organization) is also questioned because 3 or 4
organizations are not sufficient to say it is a general theory.
Q8: Thus, how can I solve this paradox? I want to develop a theory and
its tools or software, what can I do?
What can I do?
The answer is
“Critical Realism” Research.
Q9: What is critical realism research sometimes called pragmatic
research (Some authors differentiate between them)?
Critical Realism
research is a mixed philosophy. Mixed philosophy can take different forms
- Develop your theory based on interviews from small
number of organizations (Interpretivism
ontology) but you will validate the results using questionnaire (testing
hypotheses). Finally, you use the results to develop a tool using case studies. Sometimes it is called pragmatism.
- Develop dynamic hypotheses in your interviews (grounded
theory). In other words, your questions in interview guided by hypotheses. --> Many authors consider it interpretivism approach. But it considers testing hypotheses.
- Develop your theory based on case study using
interviews (Interpretivism ontology) but you
validate the results using historical records or archival analysis à this is the ubiquitous
form of critical realism.
- Doing action research by observing and interviewing
first (Interpretivism) then the researcher
act or intervene (by asking people to do something or asking organization to
use something) and then see the results.
Therefore, the researcher develops the theory based on observation and
interviews. From this theory, he develops hypotheses that tested by a real
situation. And finally, researcher document objectively the results of his/her
act. Actually, this is a loop. Therefore, based on the results and more
interviews, new hypotheses should be developed in order to ask the organization
to do specific acts to test these hypotheses. Again, the results should be
documented and so on.
Actually, a lot
of nowadays systems are based on action research. I am one of the believers
that developing a tool or software based on theory without using the critical
realism research is questioned.
Q10: So, what is the critical realism in philosophy?
In brief, you
criticize the reality that you observe. So you have to test that the reality
you get in order to state it is reality.
Q11: Okay, I know authors differentiate between realism and critical
realism philosophies?
Yes, realism believes
that what you see is real without doubt. On the other hand, critical realism is
based on criticizing the reality that we observe. Therefore, I can classify
pure Interpretivism and positivism as realism because both of the schools
focus on a single way of getting the reality. No one doubted in the way of
getting knowledge. In other words, positivists validate their way of getting knowledge (Epistemology) by validating the questionnaire (the
tool of getting the knowledge) not by validating the way of getting the
knowledge. In the same vein, Interpretivism,
validate their models by asking people about their opinions about the model.
Again the same problem they validate the model which is based on interviews by
using the interview. If interview succeed at the first time, absolutely, it
will succeed at the second time. Again we do not validate the way of getting
the knowledge.
Only Critical
realism criticizes the way of getting the knowledge as well as criticizing the
ontology of the knowledge.
Based on this
philosophical debate, your tool or your software should be validated in an
objective way (based on hypotheses) but it should be developed in an
interpretive way (based on your experience and interaction with people).
Q 12: What do you advise me?
I advise you to
read critical realism by reading PhD theses. You will not find this school in
academic papers. Why? Because it is a big project so that the researcher
publishes at least 3 journal papers from this PhD. Each Journal paper takes one
phase of research.
Q13: Do not read about critical realism from research methodology books.
Why?
First, most of
research methodology authors are either positivist
or Interpretivist. Therefore, they will
explain critical realism in a difficult way in order to make you believe it is
impossible. And the rest of the book is either positivist
or Interpretivist. So how can you read the
rest of the book if you liked the critical realism???
Second, critical
realism is an art more than science.
Therefore, it is better to read the
research projects of the leaders of action research and critical realism authors.
Q14: So, where can I find the leaders of this kind of research?
I do not know
much of them, but you can find universities accept this approach such as
University of Cambridge (IfM) (Such as Professor Stephen Evans),
Cranfield University (School of Applied Science & School of Management) Such as Professor Joe Peppard and Dr. Essam Shehab,
Bath University
(Operations & Logistic Management) such as Jens Roehrich,
University of Twente (Dr. Maya Daneva & Professor Weirenga ),
and Aston University (School of Management) (Professor Tim Baines)
You can read their PhD students theses.
Q15: Where can I read PhD theses that use critical research approach?
I upload them on
the Facebook group. Go to the group, and
click on files to download them.
