Could it be that the less interested the female INTP is in someone, the more interested that person has to be? And if the INTP is really interested in someone, they want that person to be disinterested, for fear that they will lose their autonomy?
How to seduce......mmmmm....... you gotta impress them with your intellect/originality and then feign disinterest and walk away......hook......line.....sunk.
My first instinct combined the idea of no pressure and being the kind of person the INTP would find attractive. Your statement describes one scenario to combine the two.
With anyone, but possibly moreso with INTPs, is the need to combine clarity of communication with putting little or no pressure on the person. This is true for anyone to some extent, but inward, analytical people like to arrive at conclusions based on their own thought processes. So, if you are someone with qualities like intelligence and originality that an INTP might tend to admire, then you give them good, clear information on your interest in them, but also allow them to have the time and personal space to think it through and arrive at their own conclusion about it, that is probably the best you can do.
