The Questionable Use of Moral Development Theory in Studies of Business Ethics: Discussion and Empirical Findings

The topic of the article is how moral development theory can enlighten the understanding of ethical behaviour in business. It discusses previous research on the subject, and reports an empirical study of academics (engineers and business economists with a master degree) working in the private sector in Norway.Moral development theory is based on a long research tradition, and many researchers within business ethics have assumed the importance of moral reasoning in business environments. However, the truth of these assumptions has not been confirmed by previous empirical research.The article reports on my investigation into the relationship between moral reasoning, ethical attitudes and decision-making behaviour. The data were collected by a survey study among Norwegian engineers and business economists working in businesses (N = 449) in 1997.It has been hypothesised that strong ethical attitudes would have a restraining effect on moral reasoning. In order to test this, ethical attitudes were categorized into four issue categories. The assumption being that the four categories would explain the different restraints on moral reasoning. The statistical testing showed that there was a negative, but not significant, correlation between strong attitudes and good moral reasoning ability.It was also hypothesised that good ability in moral reasoning would tend to exhibit a smaller difference between Policy-decisions and Action-decisions. This hypothesis was based on the difference in behaviour explained in "espoused theory" and "theory in use". When making policy-decisions these can be based on espoused theory and nice "talk" because it is always possible to make exceptions to or reconsider a policy. Action-decisions, on the other hand, are very concrete because they immediately trigger an action. The statistical testing rejected my hypothesis but gave a significant converse result: Good ability in moral reasoning seems to imply less stability and more inconsistence.The article concludes with the fact that moral reasoning testing seems to explain some differences in moral reasoning among people in business but not what kind of behavioural effects these differences actually have.
