Research philosophy
Session outline
 Why ‘philosophy’ ?
 Overview of research philosophies
 Some more common philosophical
approaches
 How to determine your own research
philosophy
 Let’s philosophise
Why philosophy ?
 All research is based on assumptions
 about how the world is perceived
 about how we can best come to understand it.
 Nobody really knows how we can best understand the
world
 Philosophers have been arguing about it for 1000s of
years,
 For us, as researchers, need to consider how we know
about the world around us. What is our philosophical
approach to knowledge?
Epistemology vs Methodology
 Epistemology is ‘how we come to know’
 Methodology is ‘how we come to know’
 Epistemology is the philosophy of knowledge
 Methodology is the practical ways, the methods used
to gain knowledge
 Inextricably linked of course
One philosophical view - positivism
 the goal of knowledge is simply to describe the phenomena

that we experience
study what we can observe and measure
Impossible to know about anything else
deductive reasoning to postulate theories that we can test
empiricism -- the idea that observation and measurement
is the core of the scientific endeavour
Main method is the experiment, the attempt to discern
natural laws through direct manipulation and observation
What makes this view of the world attractive?
Why have many researchers moved away from this
approach?
The enlightenment?
Post-positivism
 Rejection of positivist ideas has lead to an array of
alternative approaches
One end of post-positivism
 critical realism - there is a reality independent of our
thinking about it that science can study. Recognizes
that all observation is fallible and has error and that all
theory is revisable
The other post-positivist extreme
 Subjectivism - there is no external reality . It’s all in
our heads!
Post-positivism generally
 Multiple measures and observations, each of which may

possess different types of error,
triangulation across these multiple errorful sources to try
to understand better what's happening in reality.
all observations are theory-laden
All researchers are inherently biased by their cultural
experiences, world views etc
Most post-positivists are constructivists who believe that
we each construct our view of the world based on our
perceptions of it
objectivity by triangulation across multiple fallible
perspectives. Thus, objectivity is not the characteristic of
an individual, it is inherently a social phenomenon
Objectivity without positivism?
“ The best way for us to improve the objectivity of what we do
is to do it within the context of a broader contentious
community of truth-seekers (including other scientists)
who criticize each other's work. The theories that survive
such intense scrutiny are a bit like the species that survive
in the evolutionary struggle. (This is sometimes called the
natural selection theory of knowledge and holds that
ideas have 'survival value' and that knowledge evolves
through a process of variation, selection and retention).
They have adaptive value and are probably as close as our
species can come to being objective and understanding
reality”
William Trochim, (2002) Research Methods Knowledgebase
Phenomenology
 Phenomenology is sometimes considered a
philosophical perspective as well as an approach to
qualitative methodology. It has a long history in
several social research disciplines including
psychology, sociology and social work.
Phenomenology is a school of thought that
emphasizes a focus on people's subjective experiences
and interpretations of the world. That is, the
phenomenologist wants to understand how the world
appears to others.
Key Features of Positivist and Phenomenological Paradigms
Phenomenological paradigm
Positivist paradigm
Basic beliefs:
Science is driven by human interest
Observer is independent
The world is socially constructed and subjective
Science is value-free
Observer is part of what is observed
The world is external and objective
Researchers should:
Try to understand what is happening
Focus on facts
Develop ideas through induction from evidence
Formulate and test hypotheses
Focus on meanings
Look for causality and fundamental laws
Look at totality of each situation
Reduce phenomena to simplest elements
Preferred methods:
Small samples investigated in depth or over time
Take large samples
Use multiple methods to establish different views of phenomena
Operationalise concept so they can be measured
Easterby-Smith, Thorpe & Lowe 1994 pp. 27
Positivist paradigm
Basic
beliefs:
The world is external and objective
Observer is independent
Science is value-free
Researcher focus on facts
should:
look for causality and fundamental laws
reduce phenomena to simplest events
formulate hypotheses and then test
them
Preferred
methods
include:
operationalising concepts so that they
can be measured
taking large samples
Phenomenological paradigm
The
world
is
socially
constructed and subjective
Observer is part of what
observed
Science is driven by human
interests
focus on meanings
try to understand what is
happening
look at the totality of each
situation
develop ideas through induction
form data
using multiple methods to
establish different views of
phenomena
small samples investigated in
depth or over time
Considerations for successful research
Positivist viewpoint
Phenomenological viewpoint
Validity
Does an instrument measure Has the researcher gained full
what it is supposed to measure? access to the knowledge and
meanings of informants?
Reliability
Will the measure yield the same Will similar observations be
results on different occasions made by different researchers
(assuming no real change in on different occasions?
what is to be measured)?
Generalisability
What is the probability that
patterns observed in a sample
will also be present in the wider
population from which the
sample is drawn?
How likely is it that ideas and
theories generated in one
setting will also apply in other
settings?
Deductive vs Inductive reasoning
Circular model of research process
 Inductive: begin at A
(observation/description)
, proceed to B (analysis),
arrive at C (explanation)
A: observation/ description
B: Analysis
 Deductive: begin at C
C: Explanation/ Hypotheses/ Theory
(hypothesis), proceed to
A (gathering data to test
hyp), proceed to B to test
hyp against data
How to determine your own
research philosophy
 Consider your own research background/experience
 Consider your topic (theoretical basis, research subjects,

desired knowledge etc)
Read widely on research philosophy – there are many often
contrasting and contradictory views
Many more specific views eg relativism, subjectivism,
hermeneutics, deconstructivism, constructivism, feminism
etc.
Engage in philosophical debate with peers, supervisors,
yourself
Show this in your thesis, building a case for your own
philosophical stance
Let this then lead your methodology
Conclusions
 There is no right or wrong research philosophy, but a
well argued case for the one you prefer showing
understanding of alternatives
 Your research philosophy will guide your methodology
and your overall approach to your PhD
 It’s hard but vital! An understanding of alternative
philosophies will make you a
much better researcher.
Further reading
 Many books and articles on this
 Look for ones in your area of research as well as
general social science/business research
 Use seminal texts as well as up to date books/articles –
the debate continues.
 Look at the approaches of other researchers in your
field of study

Read the short article ‘Toward a research philosophy’
and critique the author’s approach to research
methodology
You are interested in examining management stress
in particular kinds of organisations. You want to find
out as much as you can about how it manifests itself
in particular workplaces.
In pairs debate whether this should be approached
from a positivist or post-positivist/phenomenological
perspective (one to play role of positivist other critical
realist or phenomenologist)
Repeat the above for your own PhD topics.
Read ‘All research is interpretive’ and consider the
implications of this philosophical view (homework).
