Some ideas of egoism can be studied in moral psychology. For example, Friedrich Nietzsche says that many people wrongly think that being "good" is related to being "unegoistic". Instead, this thought only happened since priestly values took over from noble values . Nietzsche says that the concepts of egoistic or altruistic actions are pseudo-psychology. In fact, "there are no such things as egoistic and altruistic actions". Morality, he says, tries to damage psychology with these false ideas. He also says that this kind of morality always serves the needs and wants of some people over others. The British researcher Alexander Moseley instead says egoists reject that psychology can understand people's motivations.
