ACE8001: What do we mean by Research?
& Can we hope to do genuine Social Science Research
(David Harvey) 



What do we mean by research? What might characterise good research practice? There is no point in us trying to re-invent the wheel - other and probably more capable people than us have wrestled with this problem before us, and it makes good sense and is good practice to learn what they have discovered.  In other words - we need to explore more reliable and effective methods and systems for the pursuit of research than we have been doing so far.

What is research?

Dictionary Definitions of Research: Howard and Sharp (HS) define research as:
"seeking through methodical processes to add to bodies of knowledge by the discovery or elucidation of non-trivial facts, insights and improved understanding of situations, processes and mechanisms".
[Howard, K. and Sharp, J.A. The Management of a student research project, Gower, 1983 - a useful and practical “how to do it” guide]

What particular cognitive and affective skills should we have aquired already?

Bloom's taxonomy of educational objectives can be taken as an approximation for the expansion and development of knowledge (Figure 1) and thus also of the objectives of research, whose purpose (other than fun and entertainment) is to expand and develop knowledge:

This taxonomy gives us some strong indications of the sorts of activities associated with research. Research is most often associated with the last four of the Cognitive objectives (taking the first two for granted as necessary pre-conditions for effective research), and with the last two of the Affective objectives (again taking the first three for granted or excluded as activities belonging to management or organisation rather than research).  However, it is seldom wise to take at least the first two of Bloom's Cognitive objectives for granted in any research effort, and part of this course (module) will be concerned with meeting these objectives.  Furthermore, the affective objectives are also important in much social research.

What does research consist of?

The general process of research can be illustrated as follows (again, following HS):

In short, the process of research consists of deciding why we want to research what we want to research, and how we think we are going to do it (the planning phase).  Subsequently, we decide how to actually do the research and then do it (what data we will collect and how, and then what we will do with these data when we have got them).  Finally, we present the results of our efforts.  Now, as a reuslt of our research, we think we know something which was not known before, and so are in a position to ask and answer the question: so what?

Notice: data are plural - the singular is datum.  Note, too, that data are generic, and include all sorts of information, from more or less highly specified and defined numbers (quantitative data), which are supposed to actually measure some quantity or some continuous or discrete quality or characteristic of the things we are interested in, to qualitative data, such as peoples' ideas and perceptions, and such as the rules and institutions which people use in carrying on their everyday lives.

Note, too, that Data collection (assembly) and analysis - interpretation involves verification (confirm the accuracy and internal consistency) and validation (confirm the coherence and applicability) of the evidence or data we are using.

However, the process of research is typically not linear, as should be obvious from the above - surely the possible answers to "so what" are important in deciding "what" and "why".  The process is circular.  The conventional (academic, scientific) cycle is typically represented as follows (following Frankfort-Nachmias, C. and Nachmias, D., (1992), Research Methods in the Social Sciences, Edward Arnold, p 22)

We can quarrel with the order of the steps round this cycle - in particular, that exploration of what we already think we know (literature and current measurements etc.) should come closer to the top, before we think of our answers to why, how and how to.  But the central pivot around which the process operates is the Theory/Methodology axis or axle.  This is a collection of current understandings, based on a collection of evidence (data) and practices in collecting and interpreting this evidence (methods), which have stood the tests of time and previous research.  In some literature, this collection of current understandings of the way the world works is known as a paradigm. The theory of market economics, and the collection of data and methods used to develop and test this theory, is a paradigm.  The theory of and evidence for atomic structure and behaviour is the paradigm underpining virtually all of chemistry and biochemistry.  The theory of and evidence for evolution and natural selection is the paradigm underlying ecology and genetics.

It is the paradigm which detemines the answer to the key question within a research process - how can we tell whether or not what we think we see is consistent or not with what we think we understand about the way the world works.

Our theory tells us a story about how data is generated in the systems we are looking at - how bits of it are related to and interact with other bits.  Our methods tell us how to look at and interpret these data and observations systematically - how to test whether they make sense (or not) with our story or theory.  The current literature and measurement are the places we go and look to find what the current understandings and stories and evidence (the paradigm) are telling us.  This literature and associated measurements (evaluations of observations) reveal the gaps and inconsistencies in the present paradigm. The objective of new research is then to fill these gaps and resolve these inconsistencies.  Easy.  Well, perhaps not easy, otherwise we would know more than we do.  But easy enough that we have made remarkable progress in understanding how our physical, chemical and biological worlds fit together and work.

Not quite so obvious that we have made the same sort of progress with our social sciences, though.  Perhaps we just haven't been doing it for long enough yet.  The process of social science research is seriously hampered by the fact that there is no commonly accepted paradigm which covers human behaviour.  Rather there are a number of partial, incomplete, and substantially separate social science paradigms:  psychological, sociological, economic, political, anthropological; all of which offer some insight into the human condition, but none of which relate closely with each other, and many of which (since there are even separate paradigms within each of the social science disciplines) are inconsistent with each other.

For example, are income distributions between people the natural consequence of economic flows and interactions, or are they the consequence of political engineering, power and control?  Obviously both - but how do the two paradigms interact?  We must suppose, I suppose, that there exists a new paradigm which might include both the economic and the political interactions - but we do not have this new paradigm yet (although there are attempts being made to develop a more general 'model' of political economy and public choice).  But even then, how does sociology or psychology fit with political economy, or even with each other?  We don't know, yet.  If we ever can hope to.

But we have to make decisions and live in this human world. To make more sensible decisions, we need to research our understandings of the ways in which our human worlds work.  Whatever we believe about the fundamental natures and processes of human behaviour patterns, we do each have some notion of how the bits of the world we live in and are interested in work.  We have certain expectations of how other people will behave in particular circumstances and contexts.  Not that these expectations are always met - we are more or less continually surprised.  But we the modify our expectations in the light of experience.  We each build up a conception, a 'model', a pattern of the way people behave and the way the world works.  So, social science might then consist of understanding how each of these patterns or world views is established and how they interact with each other - the systematics of the ways in which the world works.

So, what does the cycle of social science research look like, then?  The answer is that it tends to be customer driven to a much greater extent than biophysical science.  If you like, applied social scientists are equivalent to the engineers and doctors of the biophysical world - trying to develop better techniques and practices for living and for resolving practical difficulties, and hence responding to the demands of life - the customer.   Of course, if we are rich enough or lucky, we may also be able to simply follow our own curiosity, and not care who wants to know and why.  But we are unlikely to able to earn a living doing this - we will have to do it as a hobby. Otherwise, to do what we want to do, we will have to persuade someone to pay us while we do it, and thus persuade them that they really need to know what it is we think we can tell them.

There are three major differences in this picture of the research cycle in social science, compared with the previous illustration of the scientific cycle.

It is often said that 9/10ths, or some similar high fraction, of good research consists in asking the right questions.  What are the right questions?  If it were a simple task to identify these, we would probably not call the search for answers 'research'.  One picture which captures most of the relevant factors and influences determining 'the right question' is as follows (again borrowing from and adding to HS)

The Right Question? - Key considerations in Selection of a Research Topic

Key questions worthy of preliminary answers right at the outset are: at the end of this project, who will want to know the answers and why, and what use will they be able to make of them?  In other words - what is the answer to the question So What? when you have completed your research project. If you cannot think of a satisfactory answer to this question, then the chances are that you are not asking the right research questions - those which are capable of being answered beyond reasonable doubt..

The criteria against which research is conventionally judged are now well-established (the scientific method):

So, we should choose questions which allow us to make as much progress towards meeting these criteria as possible.  What are our options?   Recall the definitions of research above.  The strong implication of these definitions is that careful = methodical;  and methodical = scientific.  What do we mean by science?  The Oxford English Dictionary (OED) defines science as: "a branch of study which is concerned either with a connected body of demonstrated truths or with observed facts systematically classified or more or less colligated by being brought under general laws, and which includes trustworthy methods for the discovery of new truth within its own domain."

The Scientific Method:

The essence of the scientific method (elaborated in its most extreme form by Karl Popper in The Logic of Scientific Discovery, 1959) In particular, this form of scientific method seeks to avoid the temptation of induction:  generalisation from the particular or specific instance.  Just because a relationship is observed in one particular place and time, amongst a certain group of individuals, there is no logical reason for this relationship to be repeated or to hold elsewhere among other characters and cultures.  The strict scientific method attempts to avoid this logical fallacy by employing the deductive approach: postulating the possible general law or relationship, and then seeking a variety of evidence to test the relationship.  Strictly speaking, one observation or experiment which shows that the relationship does not hold is then sufficient to disprove the hypothesis.  In practice, however, it usually takes a number of disproofs to persuade us to give up a theory.  On the other hand, we can never be sure of our theory or hypothesis - it will always remain a theory, since we can only falsify the hypothesis, never prove it to be true - there may be other experiments we have not done, or other data we have not collected or yet observed, which will refute our present theories.  Proving hypotheses with empirical data uses the word 'prove' in its older meaning - to test.

Because the results of our science will seldom be clear cut, we need to be able to replicate our experiments or our data collection and analysis to be sure that what we thought we had observed as either conformation (rather than confirmation) or refutation (rejection) of our hypothesis were not simply accidents but were genuine reflections of the way the world is.  Not that every research report will contain replication of evidence or experiment - but every report should contain sufficient information to allow other researchers to duplicate or replicate the research.  The greater the number of independent studies finding the same things, the more credence we can give to the results.

Furthermore, we might still be mistaken in comparing the hypothesis with the evidence, since it is extremely difficult to be sure that our hypothesis is exactly commensurate with the evidence - the hypothesis might refer to different sorts of data, in different contexts and circumstances, than we are able to collect or observe, even as a result of a more or less controlled experiment.  There are essentially two sorts of mistakes or errors we can make in confronting (testing) hypotheses with evidence:

  1. accepting the evidence as refuting the hypothesis, when the hypothesis is a 'true' statement of the state of nature or the world (mistakenly rejecting a true hypothesis - a Type I error).
  2. accepting the evidence as conforming to the hypothesis, when in fact it does not  (mistakenly accepting the hypothesis as an (always provisional) true reflection of the state or character of the world - a Type II error)
The objective of science is to build a body of knowledge which has not (so far) been refuted.  Scientific progress consists in making this body of knowledge both larger and more integrated and coherent - so that the hypothesised laws and general connections apply over a wider field of observations and experiments - they become more and more universal, and the body of theory underlying the scientific knowledge becomes ever more parsimonious - relying on fewer a priori assumptions, assertions or axioms which are inherently unprovable or untestable.

Clearly this objective will be frustrated if we fill our pool of scientific knowledge with Type II errors - mistakenly accepted false hypotheses as if they were (provisionally) true.  Hence, the scientific approach is inherently cautious - it uses and designs tests to minimise the chances of Type II errors (which typically means that the chances of Type I errors are increased).  Scientists are trained to be cautious, and to hedge their findings and conclusions with caveats - 'please do not rely on this experiment, evidence, as the basis of what you should do next.'  In short, rigorous science always runs the danger of being irrelevant to the problems of the practical world.

A Scientific Typology of Research Approaches.

The lower arm of this figure - the research approaches which do not suppose or seek to find evidence for cause-effect relationships - might be classed as pre-scientific or a-scientific according to Popper's falsification criterion.  Yet there is little doubt that such investigations contribute to the development of science and of its associated paradigms.  For instance, much of the astronomical evidence and observation which were used to test the Copernican theory were collected without any conscious thought of testing a theory.  These data were collected as correlational or exploratory/interpretive.  In short, it is these pre-scientific investigations which are one major source of new conjectures and hypotheses about the way the world works.

Scientists are trained and bred to continually demand that more tests and experiments be done to 'confirm' that the theory - the present understanding - really does match up and stand up to experience of the world, while always recognising that the present theory may be exactly wrong, rather than roughly right.  The classic example of being exactly wrong is the theory that the sun goes round the earth.

How did we discover that it was wrong?  The answer is that science does not and cannot rely solely on empirical (observational or experimental) evidence.  It has also to rely on reason and logic - the genesis of the theory or general law.  Copernicus reasoned that an alternative hypothesis - that the earth goes round the sun - would be just as consistent with our everyday observations - the sun rising in the east and setting in the west.  Furthermore, development of this reason and logic also better explained observations of the movements of the other planets.  Thus the "theoretical - conceptual - analytical" box in the diagram above is a critical part of the scientific process, as, too, is careful use of inferrential reason and inductive logic (the lower arm of the figure).

So, pursuit of scientific methods results in a body of knowledge ( a paradigm - a coherent theory and a supporting collection of consistent empirical evidence), which is continually updated, revised and modified in the light of both theoretical developments and additional evidence, conformations and refutations, but which is always and inevitably provisional.

Perhaps the best way of characterising "the scientific method" is to think of it as making the best possible case for a particlular understanding of what is going on, or what has happened in the past and, thus what is likely to happen again in the future, or what has happened in one place and therefore can be expected to happen in other places.  This best possible case will consist of a story (theory) about why certain things happen, and evidence (data) that the story makes sense with what we see and hear.  The jury we seek to convince consists of our fellow researchers and informed participants in the actual events and behaviours we seek to examine. The judge, ultimately, will be our future experiences.

Conclusions

So What?  These notes have briefly outlined the conventional scientific approach to social science research - at least as far as your class leader (me) understands it.  There are two key messages which you should get from this outline: So, social science is difficult.  It needs a lot of careful thought and intelligent practice.  Perhaps it is actually impossibly difficult, reflecting the near infinite complexity of human existence and behaviour?  Interesting question (at least to me).  So, what is the answer?  Since it is my job as your teacher to expose you to my thinking, and it is your purpose as students to see what you can learn from this exposure, we will have a look at this question in the next set of notes.
