Find a truth-seeking group that argues with you

Surround yourself with people whose job in the relationship is to challenge your reasoning, not validate it.

Why it works

Sycophantic feedback — people agreeing with you to preserve the relationship — is among the hardest biases to overcome because it feels good and arrives reliably from people who like you. A deliberately adversarial or truth-seeking peer group creates the kind of friction that surfaces the flaws in your reasoning before they cause a costly decision. The benefit is calibration from external challenges rather than from outcomes.

How to do it

1. Identify one or two people who are known to disagree with you respectfully and value being right over being agreeable.
2. Explicitly invite them to challenge your reasoning rather than evaluate your conclusions.
3. Create a norm: "tell me why I’m wrong" as the expected response, not the exception.
4. Reciprocate by genuinely engaging with challenges rather than defending the original position.

Evidence

Group deliberation research shows that groups outperform individuals when they have diverse views and norms that encourage dissent. Groupthink and sycophancy reliably degrade decision quality in groups with strong conformity norms. (observational)

Adversarial collaboration requires relationships with sufficient trust to handle disagreement non-defensively; it backfires in low-trust settings.

Common mistake

Calling a group a "truth-seeking group" while implicitly rewarding agreement and penalizing disagreement — the norm has to be genuinely enforced, not just declared.
