The aim of market research is to explain consumer behavior. But can it actually do this, if behavior is only differentiated in regards to demography, or if only a specific type of behavior is analyzed? We at SIGMA believe in an integrated approach, which not only sheds a light on behavior in certain situations, but on the people themselves. Because people in and of themselves are different, react differently to the same kinds of offers. We believe that one can only assess the reaction to a certain product, service or communication, if one actually knows the people in question…
