In the last three columns, the authors introduced the idea of ethical reasoning, discussed its importance to education, and briefly dealt with a number of understandings essential to skilled ethical reasoning. In this column, the authors continue this discussion. They distinguish between simple and complex ethical questions and reason through an example complex ethical question. Next they discuss the fact that, when dealing with complex ethical issues, data should often be analyzed from multiple perspectives. Finally, they illuminate some important ways in which humans distort information and facts to maintain their views or serve their interests (and in so doing, often reason unethically).
