The issue of science and market research is one that can cause quite a bit of heat, but here is my two-pennyworth.
Is market research a science?
I think the answer is clearly a no. Although there are many definitions of a science I do not think it is helpful to draw the definition too widely. I define science as “The pursuit of knowledge that seeks generalisable information about the empirical world utilising the paradigm of the scientific method.” Many people would use a more narrow definition, focusing on the creation of generalisable laws, linking cause and effect, but this approach excludes the traditions of parts of the biological sciences, where the main fields of endeavour over the last few hundred years related to finding, measuring, and categorising observable phenomena.
The reason I feel that market research is not a science is that it almost always focuses on the particular, not the general. There are many endeavours that utilise science and which seek to measure and assess the world, but which are not themselves a science. For example, surveyors, tailors, people who inspect cars/engines for faults, journalists, police all examine the world but they are not scientists. Perhaps the best example of this split between using science and being a science is the role of the GP (i.e. the family doctor), doctors use the products of science, but their focus is the specifics of each patient.
It could be argued that a researcher who spent the majority of their time trying to develop a new method of price testing system was engaged in science. But a researcher who was looking at what people in the UK might pay in 2011 for a new type of home delivery might be using science, but they would not be ‘doing science’.
Scientific Method
Even if market research is not a ‘science’ can we say that it does (or should) conform to the scientific method? Again, we need to produce a definition of the scientific method, and my feeling is that it is an approach that attempts to meet the following criteria/beliefs:
- There is a real world and that world can be measured.
- The results are generalisable to some extent, i.e. the findings can be extended to a useful number of other situations.
- The researcher should seek to be neutral, i.e. the researcher is seeking to be objective.
- The method is noted down in sufficient detail that the research can be replicated.
- There is a methodological reason for believing that the research is valid (e.g. statistics, models, etc).
Many market researchers would describe most quantitative research as conforming to the model above. I thnk the two biggest weaknesses in this model are criteria 3 and 5.
Can researchers be neutral? Researchers can try to be objective, but the choice of sample, timing, questions, and method are all subjective. Two researchers given the same problem would not necessarily choose the same method, the same type of sample, and same questionnaire to conduct the research. If researchers want to claim they are following a scientific method they need to recognise their limitations and seek to minimise the subjectivity. One method that academia uses in this area is to use questionnaires that have become the ‘validated’ instrument for that test, rather than crafting a new questionnaire for every project – but would this be a popular route for market research?
Criterion 5 above relates to using techniques where there is a reason to believe they are valid. This is a becoming a major area of concern for market research as the neuroscientists, the behavioural economists, and writers such as Mark Earls are all showing that respondents are bad witnesses to their own views and intentions. At present, in market research, there is not a clear mechanism leads to methods that have been shown to lack validity being removed from the toolkit. It sometimes seen that market research is like an alternative medicine vendor who happily sells some cures that that have evidence to support them, some with big question marks over them, and some like homeopathy which have repeatedly been shown not to work.
Alternative Paradigms
Whilst most quantitative market researchers would hold to some version of the scientific method, this is not true of all researchers who study society. Within qualitative research there is a strong strand of constructionist thinking which would raise the following queries about the criteria above.
- There is not a ‘real’ social world. The social world is made by people, it is an open system, and if some rule were ever to be identified the knowledge of it would permit society to change how it performed.
- Research tends to be situated, if we study how queuing happens in Starbucks in Nottingham, on a Friday afternoon, we need to be very careful about how generalisable the findings are. To generalise the findings we need to appeal to previous research and to triangulation to show what appears to be common with other situations and what tends to be different.
- The researcher is not neutral or objective, the researcher changes the research situation and the research is a construction of the researcher. This can be miminised, but it will still be important and should be recognised.
- The research should be documented, not so it can be replicated (because it can’t be replicated), but so that the reader can take a view on the trust they want to place in the research and findings.
- The nature of the term ‘valid’ is not consistent to the idea that realities are constructed, socially. The issue of validity becomes re-framed in terms of producing results that are useful and about which we have good reasons to believe.
So, what about science and market research?
My feeling is that two big changes need to happen:
- In quant research we should accept the limitations of the scientific model in order to benefit from the paradigm, this means addressing the excessive subjectivity in the design of studies and it means discarding approaches if they are shown not to work.
- In qual we should avoid referring to it as a science, as a scientific method, or as being based on science. We need to explain that the vast majority of society cannot (in the foreseeable future) be reduced to things that can be dealt with by measurement and the scientific method. Clients need to embrace and understand the implications that underpin practical constructionist epistemologies.
Note, I am not saying that clients need to engage in the philosophical arguments about epistemology and ontology. However, at the very least they need to understand:
- Different researchers give different answers (because of design in quant and the paradigm in qual).
- If you are not an expert, judge market research in terms of past performance and recommendations.
