Free cognitive-bias Agent Skill

Value Selection Bias

Use Value Selection Bias as a focused cognitive-bias lens. Explain the pattern, check whether it plausibly fits the situation, surface an alternative non-bias explanation, and return a practical counter-check without diagnosing people or claiming causation.

What the agent should do

Use one bias carefully, not as a diagnosis.

Canonical definition

Value Selection Bias is a narrow reasoning pattern studied in Bayesian diagnostic problems. When participants did not derive the correct solution, their incorrect answers were strongly drawn toward numerical values already supplied in the problem. The effect concerns problem representation, reference classes, and solution construction; it is not evidence that people generally rely on old prices, stale KPIs, or outdated travel estimates.

Boundary

A lens, not a verdict.

The skill must preserve uncertainty, surface a non-bias explanation and avoid turning a cognitive-bias label into a claim about a person's motives, intelligence or mental health.
