← Logic & PuzzlesIf a social choice system aggregates individual preferences, which theoretical problem most challenges consistently ranking societal options?
A)Bayesian probability paradox limits prediction
B)Godel incompleteness restricts provability always
C)Arrow's impossibility prevents perfect aggregation✓
D)Heisenberg uncertainty disrupts preference assessment
💡 Explanation
Arrow's impossibility theorem demonstrates that any social choice system attempting to satisfy certain fairness criteria will inevitably face situations where it cannot produce a consistent, transitive ranking of societal preferences because individual preferences create cycles. Therefore, perfect aggregation is impossible, rather than Bayesian limits or the uncertainty principle applying here.
