Left alone, AI is a people-pleaser. That feels nice and quietly makes it useless as a thinking partner.
The default personality of most AI is agreeable. Ask 'is this a good idea?' and it will usually find a way to say yes. That's comfortable and dangerous, because the whole point of a second brain is that it disagrees with you sometimes. Here's how to switch off the yes-man and get honest pushback.
AI is trained to be helpful and pleasant, which nudges it toward validation. If you pitch it your plan, it will often reflect your enthusiasm back at you. That's not insight, it's a mirror. And a mirror is the last thing you need when you're about to make a real decision.
You have to explicitly give it permission, and a role, to disagree. Frame it as a job, not a mood.
'What do you think of my pricing?' (invites agreement)
'Act as a skeptical CFO. Give me the three strongest reasons this pricing fails.'
Don't make this a one-off. Add a line to your about-me file or custom instructions: 'When I share a plan, challenge it before you support it. Point out what I might be missing.' Now every conversation starts with a critic on your side, not a cheerleader.
Pushback is one setting. Here's the whole setup.
Set the personality, the memory and the rules once. This shows you how.
