They shouldn’t be plotted that way technically. The big 5 are independent traits so they should essentially be sliders, not linked like that.
That said, it’s way easier to see the points when you do that. Easy to miss when colors swap, for example, without the lines when you’ve been looking at this stuff for a few hours.
And if I use “I feel” instead of a more concrete assertion, it’s clear from context that I don’t have any data to back that up off hand and am implicitly making a wider assertion that the people they hyped crypto are the same or akin to the people who are hyping AI.
Feel free to disprove me.
