Ambivalence is abhorred because it paralyzes approach-avoidance action

Evidence

Ambivalent feelings are mixed feelings, positive and negative sentiments concentrated on the same object. As Freud always assumed, it is human nature to abhor ambivalence. Behind this abhorrence, I suspect, is the fact that ambivalence must tend to paralyze action. If one likes an object or person the thing to do is to approach and if one dislikes to retreat. Ambivalence must activate both tendencies but it is impossible to act on both. — John T. Jost and Jim Sidanius, Political Psychology, 537

Categorization

• DEFINE: Defines ambivalence as mixed sentiments on one object and then derives why it’s intolerable: it blocks the motivate action because approach and retreat cannot both be enacted.
