Homo economicus
Further critics, learning from the broadly defined psychoanalytic tradition, criticize the "Homo economicus" model as ignoring the inner conflicts that real-world individuals suffer, as between short-term and long-term goals ("e.g.," eating chocolate cake and losing weight) or between individual goals and societal values. Such conflicts may lead to "irrational" behavior involving inconsistency, psychological paralysis, neurosis, and psychic pain. Further irrational human behaviour can occur as a result of habit, laziness, mimicry and simple obedience.
