Lexical studies in psychology and Latent Semantic Analysis in computer science were introduced a half century apart to solve different problems and yet are mathematically equivalent. This isn’t a metaphor that works on a certain level of abstraction;
Hi I know I'm late, but I'm very interested in this and had a question: Do you know of any studies that a dynamic approach to this topic -- i.e., attempt to trace the change of personality components over time? I was inspired by this piece (https://arxiv.org/pdf/1711.08412.pdf) that looked at stereotypes of women and minorities using the Google Books corpus. I'm interested in the extent to which gender differences in the big 5 hold up historically, which of course raises the question about whether the entire construct holds up historically. I have strong priors that it does NOT, but I can be convinced. Thanks for your time.
I should probably write a blog post somewhere on this, but it really doesn't surprise me that these are vectors. I think what we call "personality" is just emotional responses to common situations.
In Plutchik's Wheel of Emotions model there are 8 emotions that can be split into 4 pillars.
Prediction👁️: Anticipation and Surprise
Threat🗡️: Anger (Dominion) and Fear (Submission)
Morality⚖️: Respect and Disgust
Affect😂: Joy and Sadness
From a biological perspective there is only really "the self" and the environment "the world". Personality is our emotional interactions between those two.
Openness/Intellect: Surprise between the Self and the World
Openness: "do you find surprise in the world unthreatening".
Intellect: "does surprise in the world produce joy".
Extroversion: Joy and Anger between the Self and the World
Enthusiasm is "do people bring you joy"
Assertiveness is "when people threaten you do you dominate or submit"
Conscientiousness (tribe relations): Morality between the Self and the World Industriousness/Orderliness is "will coworkers find you respectable (Morality)"
Agreeableness (Affect and the World): Sadness and Fear in the World and the Self's response. Compassion/Politeness: When people are sad/afraid does that make you sad/afraid?
Neuroticism: Are you more governed by the Carrots or the Sticks of emotions? High Neuroticism means you react strongly to the sticks.
Having read your interesting article here, you might find my work on the Adaptive Bifurcated Big-Five useful. It’s a different application of vector analysis to the topic than this, but I think it’s very promising. I think I’ve done a pretty good job modeling the cross-correlations in the Big Five Aspect Scale by applying the theory (a minor rotation aligning it closer to HEXACO, followed by a bifurcation into competing adaptive cognitive systems within a single evolutionary domain) to map each assessment question within a 5d vector-space, aggregate them into aspects and factors, and then use the dot-product to compute their similarity. As an engineer though rather than a scientist, I’ve taken the ideas about as far as I can on my own. I hope you’ll take a look. It has a lot of practical applications, as well as adding significant parsimony to the science.
What are the three factors extracted in the unrotated model? Are they like the ones Eysenck first noticed or something else?
