It's kind of necessary when it comes to confrontation situations. Other people do the same thing, but in a seemingly more automated way. So after a while responses become somewhat predictable, which allows for preparation to handle those responses.
There is usually some recycled BS that you have to get out of the way whenever trying to resolve a situation with someone, especially in the workplace, for example. Trying to figure out how to get past the recycled BS phase without being dragged into 5,000 side-arguments can require some experimenting in my own mind, trying to play both sides and poke holes in my strategies until I think I have come up with something solid.
For me the alternative is to just be completely uncooperative and ignore people/problems, but then if I'm suddenly forced into a confrontation situation, without preparation my agitation level quickly goes through the roof. The aftermath results is that I will then spend the following days/weeks obsessing over what I should have said, but didn't. It might even pop up randomly to haunt me like 5 years later.
