Lol, that gif.
I'm pretty sure that all introverts are 'sensitive' in the neurophysiological sense, but I just didn't understand the objection here.
It seemed more like risk-aversion for a projected negative outcome, rather than trust in a positive one.
And the spoiler information was to clarify.
Short of having this escalate in a downward spiral
@Deleted member 16771 , many people do not want to be analyzed through every comment they make here in the forum, directly or indirectly. As a result, a person tends to voice up in a polite way of saying stop, be it a funny comment, emoji, or, out right saying so. An objection is a propper way to stop or divert conversation. What is often overlooked, be it the person is INFJ, or not, a person with trust issues will feel the waters before deciding if the outcome is going to be a positive one.
The receiver can not know the senders motive with certiantly, thus, a sensitive person will indeed pick up on the vibes of the sender, Ni will make the decision for the outcome and the receiver will be aware after that ripple takes affect.
In other words, "it" is a perceived risk assessment not risk aversion in the sense you refer to it. Ni is always at work receiving data and making the necessary adjustments for the user in regards to what is needed and what can pass away...usefulness.
Neurophysiology can be contrasted with neuropsychology here. It is not the wiring itself, but rather the parts of thought closepined to that wire that are snatched, collected and stored in rapid fire until built into an understanding. This is the A-ha moment many INFJ's are referring to.
