How this layer reinforces, counteracts, or depends on the rest of the system.

  • Explains·Layer
    This layer explains Human Needs & Meaning

    SDT's needs map onto ancestral fitness signals: autonomy = agency, relatedness = coalition, competence = status.

  • Explains·HBE
    This layer explains Tribalism

    In-group preference is an ancestral coalition-detection adaptation, not a modern pathology.

Elements in this layer

36 HBEs
COGBarnum Effect

We accept vague, general statements as personally meaningful.

SOCBehavioral Game Theory

Game theory adjusted for how humans actually play — including fairness, reciprocity, and limited reasoning.

INCBureau of Indian Affairs Trust Delays

Federal oversight intended to protect tribal assets creates friction that devalues the land.

INCBusyness as Status

Being visibly busy signals importance regardless of actual output.

COGCharacter Assassination

Deliberate, sustained effort to damage someone's reputation.

INCCollege Prestige Signaling

Employers screen by school name, rewarding admission rather than developed skill.

COGCostly Signaling

Signals whose value depends on being expensive to fake.

INCEngagement-Maximizing Algorithms

Ranking systems trained on engagement amplify outrage, fear, and tribal content.

COGFairness

A social preference for equitable outcomes, even at personal cost.

INCFairness Metrics

Quantitative measures of model behavior across groups.

INCHeadcount as Status

Managers measured by team size grow teams beyond need.

INCIdentity-Coded Politics

Tribal identity markers reward in-group loyalty over coalition-building.

SOCIn-Group Bias

We extend more trust, benefit of the doubt, and rope to 'our people.'

COGInequity Aversion

Distaste for unequal payoffs — including when we'd benefit.

COGInequity Aversion (Fehr-Schmidt)

People sacrifice payoff to punish unfair distributions — even unfairness that benefits them produces guilt-style discomfort.

COGJustice

Perceived fairness of outcomes, process, and treatment.

COGKin Selection

Behavior that benefits genetic relatives at cost to oneself.

INCLoyalty Program Consumption

Status tiers and points push consumption beyond actual need.

SOCOut-Group Homogeneity Bias

We see 'them' as more uniform than 'us.'

BIOOxytocin

Neurochemistry of trust, bonding, and in-group loyalty.

COGReciprocal Altruism

Cooperation between unrelated agents when future reciprocity is likely.

COGReputation

Stored social capital from prior behavior.

INCSandbagging Adoption

Teams under-reporting AI capability to protect comp or status.

BIOSCARF Model (Rock)

Status, Certainty, Autonomy, Relatedness, Fairness — drivers of social brain response.

COGSocial Preferences

Preferences that depend on others' outcomes — fairness, reciprocity, altruism, inequity aversion.

COGStatus

Position in a hierarchy is a primary driver of behavior.

SOCStatus Games

Much of human behavior is positioning for status.

COGStatus Quo Bias

Preference for what already exists, simply because it exists.

BIOStatus Quo Bias (Neural)

Brain weights existing state heavily.

BIOStatus Threat

Threats to status trigger the same neural alarm as physical threats.

INCStatus Threat (AI)

AI doesn't just replace tasks — it threatens identities.

COGTribalism

Strong in-group loyalty paired with out-group skepticism.

COGVeblen Effect

Demand rises with price because the price itself signals status.

COGVeil of Ignorance

Design rules without knowing where you'll land under them.
