I am not saying that INTjs are pushovers, they will just avoid getting into :Se: areas, not necessarily by yielding.
So, yes, if put into a situation where they have to exercise Se over others, I think the INTp will more naturally do it than the INTj, even if in other situations the IJ INTj may appear more "rigid" than the seemingly easy-going IP INTp.
