I think if you are an INFP female, this drive for balance might lead you to balance your subjective feelings and values with what you can confirm in the outside world. Being Fi dominant you would want this function to be very reliable, and so balancing it with outside information is especially necessary. When you have opinions based on value judgments, and use those to create change in the world, you would want to make sure those opinions were based in reality and that those changes would be feasible and effective. I would say the same is true with INFP men, but I would think they would be less likely to question their own opinions. The decision making process would probably be quicker.
