Your ethics are that set of abstract principles and measurable standards you use to enable you to think and act as rationally as possible. To purposely thwart your ability to think and act rationally, or to allow allow that through neglect, is unethical.
One can derive an ethic by first understanding what beliefs, behaviors and other factors thwart rational thinking in yourself, and then second determine, by experiment, the principles and standards which allow one to manage one’s roadblocks to rationality. Ethics has nothing to say about the content of your rational thought, for that is the realm of morality.
