There's a specific way a lot of people have started using AI that feels reasonable on the surface but tends to produce weaker outcomes than they expect: making a decision first, then asking AI to check it. "Does this plan make sense?" "Is this the right call?" "Can you sanity-check this approach?" These questions feel like due diligence. In practice, they're often asking AI to validate a decision that's already been made, and AI is structurally not very good at that particular job. The distinction that matters here is sequence. AI brought in before a decision is formed and AI brought in after a decision is formed produce genuinely different kinds of value, and most people default into the second pattern without realizing the first would usually serve them better. ------------- Context ------------- When AI is asked to evaluate a decision that's already been presented as the plan, it tends to find reasonable support for that plan, because the framing of the question shapes the response. Ask "does this make sense" about almost any coherent plan, and a capable AI model will generally find a way to say yes, with some caveats, because most reasonably constructed plans do make some sense, and the question as framed is oriented toward confirmation rather than genuine challenge. This isn't a flaw exactly. It's a reflection of how these tools respond to framing. A question asked in a confirmatory posture tends to get a confirmatory answer, unless the plan is genuinely and obviously flawed. The subtler problems, the ones that a good second opinion is actually supposed to catch, are much less likely to surface when the question is framed as "check this" rather than "help me think through this from scratch." Contrast this with AI brought in before a decision has formed, asked to help explore the problem itself: what are the options, what are the tradeoffs, what am I not considering. This framing produces a genuinely different quality of engagement, because there's no existing conclusion for the response to gravitate toward. The AI is helping construct thinking rather than validate a thought that's already complete.
