Free cognitive-bias Agent Skill

Declinism

Use Declinism 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

Declinism is best treated as an umbrella label for broad judgments that conditions have declined relative to an idealized past. It is not one standardized cognitive bias with one mechanism, and it is not proof that a reported decline is imaginary. Research supports narrower processes that can contribute to some decline judgments, including rosy recollection of past experiences and the well-studied illusion of moral decline.

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.
