empirically, there often tend to be "clusters of directions" and these appear as "radial streaks".
This was first noticed by Thurstone, the inventor of Factor Analysis.
heard of “topic modeling”? they generate streaks!
More generally, *varimax* after pca is a great way to find these streaks.

In closing, we consider the consequences of underfactoring. As Thurstone put it in 1947: "Too many factors can do no harm, but too few factors are sure to cause trouble." Unidimensional scales permit simpler measurement and theory -- but it's for naught if they're invalid.

If you are curious the first use I could find of the term "autism" refering to inward vs outward thinking was from chapter 10 of "The Nature of Intelligence" By Louis Leon Thurstone from 1927. At least according to google's ngram viewer.

Pairwise comparisons leave out something important: correlations between preferences. Ranking three options can recover information that two-way choices alone cannot.
Why asking people to rank three options could sharpen AI and recommendation systems
In his 1927 paper, "A law of comparative judgment," the American psychologist L. L. Thurstone proposed that when people select one option among multiple alternatives, they are picking the one that has the highest value to them, even though they cannot assign a particular number to that choice.

Then came Louis Thurstone and Raymond Cattell who proposed other models, emphasizing multiple intelligences or broad categories of intelligence, further developing the idea of domain-specific abilities.

Disinterested parties can be really helpful, too. Way back in 1924, psychologist L.L. Thurstone wrote in The Nature of Intelligence, “If we have nothing personally at stake in a dispute between people who are strangers to us, we are remarkably intelligent about weighing the evidence.”
