#76. Role of personalities in the human swarm intelligence [population]

PO

Red, theory; black, fact.

Précis: each of the Big Five personality traits is a dimension along which people differ in some socially important behavioral threshold. These are, respectively: openness > uptake of innovations; conscientiousness > uptake of taboos; extraversion >  committing to collectivism*; agreeableness > becoming militant; neuroticism > engaging in/submitting to persecution. The personality trait is written on the left of the ">" and the putatively impacted social threshold is on the right.

These threshold spectra enable social shifts that are noise-resistant, sensitive to triggers, and rapid. Noise resistance and sensitivity together are called good “receiver operating characteristics,” a concept often used in the scientific literature.

A metaphor that suggests itself is lighting a camp fire. The spark is first applied to the tinder. Ignition of the tinder ignites the kindling. Ignition of the kindling ignites the small sticks. Ignition of the small sticks ignites the big sticks, and everything is consumed.

Orderly fire-starting appears to require a spectrum of thresholds for ignition in the fuel, as may orderly social shifts. To further extend the metaphor, note that the fuel must be dry (i.e., situational factors must be permissive).

11-07-2022: Social novelties spread upward to higher-threshold social strata by meme propagation reinforced by emotional contagion. The emotional energy necessary for emotional contagion would come from the individual’s interaction with the novelty, which would feature a positive feedback.

17-11-2024: The governing neuromodulators of personality may be as follows (See my post, “Neuromodulators as Peril Specialists”):

Acetylcholine-Openness

Noradrenaline-Neuroticism 

Serotonin-Agreeableness 

Histamine-Conscienciousness

Dopamine-Extraversion 

Our capacities for all of the enumerated social shifts were selected in evolution and most can be assumed to be still adaptive when correctly triggered. In today’s world, shifts to persecution are probably the least likely to still be adaptive, and could be a holdover from our Homo erectus stage. Persecution leads to refugee production, and refugee production could have been the reason that guy was such a great disperser.

As the geologists say, “The present is the key to the past.”
