Agreeable people are more likely to shift their expressed views to agree with those they are talking to.
If they're more likely to shift their views, we call them "gullible", not "agreeable".
But this is a distinction you can't apply to language models, which don't have views.
Agreeable people are also the most suggestible in that they are the most likely to actually change their views. These traits share the same axis.
