In the context of giving commands:
~ Ti/Fe types might be more inclined to explain themselves
when asked, however they might not be pleasant about it.
~ Te/Fi types might be less willing to explain 'why' and expect you to 'just do it.'
~ Alternatively, a Te type might be the one to explain why
without being asked.
~ When a Te type does explain why, it probably is meant to be short and to-the-point and may overlook something or at least appear to do so. At this stage though one might reasonably expect to carry on a conversation regarding the logic of their commands.
~ Either type should be willing to entertain a small amount of insubordination as it is usually a catalyst for change, risk assessment notwithstanding.
~ Perception functions play a major role in all this.
~ The opposite might be more true in all cases.
When it comes to advice...
Te probably is more likely to deliver blunt and/or harsh advice and if the person isn't careful it can also carry overtones of sarcasm and condescension.
This is still different from giving commands in that you're not actually expected to follow it, however a TJ might think you're kind of dumb or silly if you don't follow their advice
without a good reason.
A word about Te in general:
From time to time on this board when the topic of Te arises I have noticed a pattern that some posters seem to think TJ types won't listen to reason after they have their mind made up. This is only a little bit true some of the time. One only has to be persuasive and conclusive in their logic and be willing to share it in a linear fashion (this->this->this). Be prepared for it to get rejected if there are obvious shortcomings (therefore, not listening to reason ...
your reason, that is)....
[Example]:
Clockwork, you betray yourself with words like 'always' and '99%' because you're wrong before you finish your sentence. You should practice evaluating your own posts more for logical errors.
You dispute the idea that Te-types deliver the most unsolicited advice by saying, oh, no that's not advice, those are commands. Advice is what Ti people do. Fallacy!
^That was unsolicited advice that might have come across as condescending. [/Example].
