Ti is a comparison function; it you look at what you wrote and what you're writing to eliminate contradictions, than you're doing Ti because the end result is that what you said and are about to say match, so you're not being contradictory. You also notice this in others and what they write or say. By eliminating variables or information, they make systems.

When you're Ti PoLR, you can often make contradictory statements, realize that you've done so but ignore in fixing it because you don't want to appear that way to others. Anyone pointing out your contradictory statements is using Ti and offering up information to you through that function and causing you to either feel like they are helping you in strengthening that function, or pressuring your PoLR over time.
