A woman approached Senator Adlai Stevenson when he was running for president, saying, "Senator, you have the vote of every thinking person!" The senator is often credited with responding, "That's not enough, madam, we need a majority!" Which concept does this quip best reflect?

Rational Ignorance

Explanation: The conversation above best reflects the concept of rational ignorance which could be explained as an idea of deciding which informations, stress or things are necessary while intentionally leaving out those deemed irrelevant as the cost outweighs the benefits. The senator is of the opinion and quite rightly that candidate with majority of the votes win and not votes from from the right thinking individuals. Here, the cost of ensuring that the right thinking person votes outweighs the benefits it provides as it doesn't give or provide what is required to be victorious.
