The Arrow impossibility theorem, also known as Sen's impossibility theorem, states that it is impossible to design a voting system that consistently represents the preferences of voters. This is because any voting system will inevitably violate one or more of the desirable properties such as universal suffrage, transitivity, or independence of irrelevant alternatives. This theorem highlights the flaws in democratic decision-making and the difficulties in creating a fair and effective voting system.
