An AI trained to psychoanalyze people analyzes Biden and Trump. Despite the AI system being called "Jung", it doesn't appear that it is trained on Jungian psychology specifically, but psychology generally. It gives Big 5 personality traits, with the addition of autonomy and altruism which he (Nathan Rice) considers not adequately captured by the Big 5. (There are a lot of traits that have been researched by psychology researchers that are omitted from the Big 5).
I suspect this is built by giving specialized instructions to a mainstream large language model such as ChatGPT, but I don't know.
