Psychology & behavior
Risk, rank, mating, bargaining. Instruments with names, not adjectives.
Economic risk tolerance
Preference over lotteries, usually measured with Holt–Laury or similar choice lists.
Status seeking
Motivation to gain or defend rank. Can be pursued via dominance or prestige.
Dominance strategy
Rank via coercion, intimidation, or formal power. Costly when institutions punish it.
Prestige strategy
Rank via skill, knowledge, or valued contribution. Others copy you voluntarily.
Leadership effectiveness
Rated or revealed ability to coordinate a group. Not the same as being chosen as leader.
Ultimatum rejection
Willingness to destroy surplus rather than accept an unfair split. A fairness-and-status task.
Sociosexuality (SOI-R)
Orientation toward uncommitted sex. Measured with Penke and Asendorpf's revised inventory.
Cognitive performance
Attention, memory, and processing speed under a named task. Not IQ-as-destiny and not a CEO score.
Youth / fertility preference in partners
Stated or revealed preference for younger or higher-fertility-cue partners.
Income hypergamy preference
Preference for a partner with equal or higher economic rank. Historically female-typical in surveys.
Educational homogamy
Assortative mating on education and cognitive class. The quiet successor to strict income hypergamy.
Interpersonal trust
Willingness to transfer resources to a stranger who can keep them. The trust-game object, not a vibe.
Contest outcome (win / loss)
Who won the last status-relevant contest. The trigger in winner–loser models.
