Aristotle and Mill offer complementary ways to judge when an AI answer needs further challenge, and when it is reasonable to decide and move on.

What Aristotle and Mill can teach us about deciding when one answer is enough.
Accept the first answer and you may miss something. Seek too many opinions and a simple decision becomes needlessly complicated. AI amplifies both temptations.
Mill makes the case for challenge. “He who knows only his own side of the case, knows little of that.” When a decision matters, AI can test the initial framing by producing competing analyses.
Aristotle argues that the degree of scrutiny should fit the question. He writes that “it is the mark of an educated mind to expect that amount of exactness in each kind which the nature of the particular subject admits.” In other words, a routine decision does not warrant the same scrutiny as a consequential judgement under uncertainty.
How much scrutiny a decision deserves comes down to the potential cost of a mistake and whether another perspective would meaningfully alter the choice. When those considerations justify further scrutiny, have AI produce competing analyses and synthesise them. Otherwise, it may be better to decide and move on.
