Majority voting fails to incorporate the strength of the preferences of individual voters and therefore?

Answer: It produces inefficient economic results under certain conditions

Explanation: The above situation is known as the paradox of voting, which tries to show that the cost of voting will always be higher than the result obtained from the voting process. This is because Majority voting undermines the importance of an individual voter. This issue was first highlighted in 1793 by Nicolas de Condorcet, where noted that in a single stage election the influence of a single voter reduces as the number of voters increase.

The paradox of voting further highlights that the expected results/outcome of a voter from an electioneering process is less than what the initial expectations.
