Trivers on Self-Deception

A clean exposition of Trivers' theory of self-deception. Signaling assumes our stated reasons are false; actions and thoughts are both selected behavior. The evolutionary arms race between liars and lie-detectors (Ekman's 'truth wizards,' ~1 in 400, which the psychic unity of mankind suggests should be trainable rather than innate) creates pressure to beat the detectors from the inside: consciousness as 'the public relations agency of the brain,' given sanitized access to the unconscious so it can broadcast a flattering story without detectable falsehood while the unconscious pursues whatever has the highest expected reward. Homosexuality case study: homophobia as reaction-formation (the often-cited, weakly-replicated penile-erection study), the unconscious objecting to gay urges and the conscious mind sincerely toeing the line. Ties signaling, self-promotion biases, and the demotion of consciousness from decision-maker to side office.

Quality 72 · Strong. Strong-ish but expository — a polished, idea-rich presentation of Trivers (the 'PR agency of the brain' framing and the reaction-formation case are memorable), held at 72 because it conveys Trivers' theory rather than contributing original synthesis, and overlaps the stronger Ego-Syntonic post (76).

Claude’s paradigm shift 42 · Moderate. Moderate — exposition of Trivers' established self-deception theory; the signaling framing and the homophobia application supply the freshness.

Real-world impact 2 · Minor. A polished exposition of Trivers' theory of self-deception (consciousness as 'the PR agency of the brain'; the reaction-formation case). Conceptual/expository influence within rationalist discourse, conveys Trivers rather than originating, no material change — low RWI.
