Personality folks, is there an argument to be made for latent Big Five traits that exist independently of the particular test we happen to use to assess them?

Now published in Current Opinion, we show why personality research should embrace multi-rater studies and how this can be achieved in practice, even at scale. Often, this is the most realistic way to avoid (reliably) invalid conclusions.

New episode!! 📣🎙️
A conversation w/ @renemottus.bsky.social about the science of human personality.
The "Big Five" model of human personality has been enormously generative and influential. But what does it miss? What does it mask? Where should the field go next?
