Angus Fletcher's Primal Intelligence and the Intellect Facet (O5)

Angus Fletcher is a neuroscientist and story scholar who argues that the intelligence that matters most is not the kind an IQ test measures. In Primal Intelligence he makes the case that the human mind is built to reason through narrative, stated plainly in an excerpt from the book: "The human brain is real-life smart because it thinks in story." That appetite for thinking, ideas, and working the world out is, in the Big Five, one facet.

The hunger to think is the Intellect facet

That facet is Intellect (O5), under Openness, the pull toward ideas, reasoning, and the pleasure of figuring something out. Fletcher's project is a defense of high O5 in a wider form than usual: intuition, imagination, and common sense counted as real intelligence rather than dismissed as soft. A high scorer likes to chew on problems and trusts the mind's ability to reason its way somewhere new. A lower scorer stays more concrete and practical, and may find Fletcher's expansive picture of thinking more abstract than useful.

The claim that gives the book its edge is that story is not decoration on top of logic but the actual machinery of human reasoning, the way the mind runs scenarios, weighs choices, and imagines what has not happened yet. That reframes intelligence as something closer to the imaginative power to picture the possible than to raw calculation. For a lower-O5 reader the usable idea is permission, since the intuition and gut narrative you already use to make sense of people count as thinking too, not a lesser substitute for it. The machines are getting good at pattern-matching. Fletcher's argument is that thinking in story is the part that stays human, and worth trusting more, not less.

Read your O5 to know how Primal Intelligence lands. If it runs high, the book flatters and widens an appetite for thinking you already have, and hands it new respect for intuition. If it runs low, it makes an unfamiliar case, that you are smarter than a narrow test would say and that your storytelling mind is doing real reasoning. The definition of intelligence keeps narrowing as the machines improve. Fletcher spends the book arguing it should go the other way.
