To me it looks like Fs have one "strange" habit.
It looks like that the Fs in many situations are thinking /feeling that the other person is in the same state as they are.
The more presure there is in a situation the more likely this is to happen.
In case that there are two/few Fs in same situation then this works.
But if there is a T in the equation this principle does not work anymore.
The possibility of an F to miss the real state of another person grows with with T of other person.
