We've talked about which information aspect behavior is related to before, and I'd like to reopen that conversation.
In a description of Te, I'd mentioned behavior. Some people said that behavior isn't Te, it can be other information aspects as well, such as Fe, etc. If I'm not mistaken, at the time I had said that depending on how you look at it and how you define "behavior", other information aspects may involve behavior as well. I've thought about it a bit more, and I disagree.
For the sake of this thread, behavior means "the activity of something". That said...
At this point I'm willing to go as far as to say that behavior pretty much "is" Te. Keep in mind that we all use information from all of the information aspects.
