One way of thinking about this study is in terms of semantic relations. Ask yourself the following questions, they might help with understanding the value of a study like this: Will different people answer these personality questions differently? Do some people have similar personality traits? Can specific viewpoints be predicted, to some rational degree of error, based on how they answer these questions? Assuming the people answering do not get any feedback from answering in a specific way (i.e. the questionnaire is a black box), and correlations can be found in the data, and predicted viewpoints can be tested against the answers, then the scientific method here is sound. From an engineering point of view, it makes sense that the results of such a questionnaire can be useful in understanding the way that people think. Of course some people will be fuzzy or erratic and not conform to a regression, but we see that all the time in every practical scientific branch (excluding most maths, in my experience).
