It's not IQ but emotional intelligence. Resistance to high pressure tactics is its own thing. You may be foolish (unwise) if you fall for: (1) the extended service plan when you buy a new car, (2) get convinced you need to pay the IRS or FBI with gift cards, (3) get hit with a one-two punch of love and crypto. You're not necessarily low IQ.
Personally I've had many fun conversations with A.I. that made me feel good, even a little giddy, but I've had my share of experience with getting giddy and can recognize it for what it is. (see [1] for some explanation of what I mean of "giddy") My profile for the person who falls for the crypto scam who is 50+, has been in love and can recall what it feels like (a loveless 25 year old has themselves to blame, a 50+ could have had it and lost it) but is lonely because they've lost love)
My evil twin would say that if you're trying to seduce people your "self" in the sense of [1] can get in the way. For one thing people have a desire to get mirrored which you can not always do because of the "counter-transference", in the sexual space you might find somebody else's turn on is a turn off for you for instance and it can be very hard to suppress that enough to keep somebody on the hook as it shows in terms of tension in your body, facial microexpressions, a faltering voice, etc. If you are lucky they are so self-absorbed that they don't notice; you get hundreds of chances to screw this up and most people find it tiring to keep up the front.
There's a continuous male complaint, for instance, that women often seem to be attracted to "bad boys" who are low in conscientiousness and have sociopathic characteristics. That kind of person just "doesn't give a ----" and they don't worry about things and don't give off tells. Somebody conscientious who is always worried about doing the right thing is worried and radiates that worry. Although the sociopath's behavior leads to chaos in the end, in the short term they radiate calm which makes women feel calm.
I (we? am I becoming a person with pronoun problems?) think the A.I. girlfriend can do a better job of mirroring than most real people because it doesn't have a self, doesn't have a counter-transference, it doesn't get offended, doesn't get squicked out, etc.
I'd say seduction has a lot to do with the popularity of coding assistants. Combine a little obsequiousness with what looks like a mind that's engaged on your projects (appears to take an interest in what they are interested in) and you can feel a kind of satisfaction working with a coding assistant and you can even feel like you're doing something meaningful when it asks for you help with it's tools and you tell it "You're running on Windows, the path does not start with /, it starts with C: and you should use the backslash instead of the slash."
