She's also an alien with very little experience with human social ques, and lacks the social expertise that other succubi have, preferring to tinker and adventure then seduce and socialize.

What's more, Maxima has odd biology in comparison to normal humans. Different pheromones and subtly different cues as a result.

So far, I don't think we've seen anything that suggests Dabbler is good at reading human emotions beyond lust.
Very little experience? she does hang out with them all day, and are able to observe them in all sorts of situation. She certainly wont have the ability to manipulate people like a socially focused succubi, but being a super genius she should have all she needs to know about how you read humans.

And source on Max having different pheromones and subtly different cues? because so far her emotional have seemed pretty easy to read.

Else, well she seems to have a rather good understanding of people, knowing how and how far she can press Max's buttons, understanding about her Stalker but pretending not to notice to let the people in charge feel safer with her around.
To me it all adds to someone with a keen understanding of humans.
