The False Consensus Effect
A cognitive phenomenon where false consensus systematically influences perception or decision-making.
False Consensus Effect is a cognitive phenomenon identified in behavioral science that shapes how users perceive, remember, and decide. In product design, False Consensus Effect explains why users behave in ways that seem irrational from a purely functional perspective. Products that understand False Consensus Effect can design experiences that work with human psychology rather than against it. Products that ignore False Consensus Effect create friction, confusion, and abandonment. False Consensus Effect is one of many cognitive effects that form the behavioral substrate of JTBDUX thinking.
