The ways of handling problems of IT systems usability and problems of ethics are similar to each other. Working with usability leads most often to the need of discussing problems of ethics, and today’s issues of ethics are mostly related to IT. The nature of IT and ethics seems to be very close to each other. Ready-made answers cannot be found and any solution proposed is easily contested. IT design and use have a strong connection to values. With classical and modern philosophy as a foundation, and based on psychological research on ethical decision making, it is suggested to focus on the way to take care of issues rather than on normative aspects or on the construction and application of usability standards and guidelines. It appears that the method used to handle problems in these areas is of crucial importance; and this is also common to both of them.
