Oh, hey, Crash Course have done a video about measuring personality
That’s kind of my thing. Although the video talks more about trait theory and self than concepts behind how we measure it, which is what I’m interested in, it’s pretty cool. It notes that traits are used to ‘predict behaviour and attitude’ but it doesn’t really get into the idea that we’re only using models and hence the models are infinitely variable. The simpler your model (e.g. the big five personality traits) you have less power to predict specific behaviours, but it’s general enough to apply to most humans and even some other animal species. That’s why we tend to go for the two-trait model for animals (also known as active/passive coping).
Anyway, I’m just bitter because my massive paper on the subject hasn’t been published yet.
And it would be really cool if we could try floating imaginary scenarios past animals . . .
