The investment theory:

"Briefly, the investment theory is that gf is a generalized inherent capacity to perceive relations, based on total volume of effective cortical cells. In the course of school and life experience this potential enables the individual to perceive and commit to memory all sorts of relations he perceives in the real world. One can think of gf as describing the power of a process and gc as being the product resulting from gf and experience."

Intelligence, 1987  - Raymond B. Cattell

Beyond purely 'rational' choices:

"Now, let us think of the new mammalian brain as having evolved as a sort of portable computer, an information-processor capable of doing simulations with great speed and clarity. It is 'programmed' to calculate the path of least pain and greatest pleasure. But, as we have seen, the resulting calculations at times fail to enhance inclusive fitness. At such times, selection will favor the 'overriding' of the new mammalian brain. ... We experience these overrides, subjectively, as emotions. This does not mean that this is all there is to the emotions or that they serve no other functions, of course, but they do seem to be associated with what is tempting to think of as limbic-system overrides of the neocortex, of the old mammalian brain overriding the new."

Robin Dunbar on Monogamy:

"a monogamous pairbond might actually be much more psychologically demanding than any number of casual relationships."

Robin Dunbar

William James on Hyperthymic and Dysthymic Temperaments:

"The sanguine and healthy-minded live habitually on the sunny side of their misery-line, the depressed and melancholy live beyond it, in darkness and apprehension. There are men who seem to have started in life with a bottle or two of champagne inscribed to their credit; whilst others seem to have been born close to the pain-threshold, which the slightest irritants fatally send them over."

William James


"People learn prestige criteria, in part, by focusing on the attention structure - those high in prestige are typically those to whom the most people pay the most attention (Chance, 1967)."

David M. Buss
"dominance, once attained, is attention-getting in its own right."

Frank Salter

"Members of a group pay far greater attention to the activities of the high- rather than low-ranking members."

Bonding in Human Relationships:

"When it comes to bonding our relationships through the endorphin mechanism, we do have a bit of a problem. We live in super-large social groups where not everyone is as familiar with each other as they are in small monkey and ape groups. At one level, our solution to this problem has been to invent conversation. But conversation on its own is very dull stuff and hardly the basis for an intimate relationship. What we seem to have done is to use laughter to bridge the gap, because laughter turns out to be a very good releaser of endorphins. Laughter seems to produce a more generalised effect that applies rather more equally to everyone who happens to be in the conversation at the time, whereas physical contact is very much a one-on-one thing. Laughter allows us to trigger an endorphin effect in a less risky way."

Robin Dunbar
