my understanding is that the Ignoring function is understood easily, automatically, and well enough that people don't expect or want others to help them with it. however, it is used privately and is not directly verbalized; people do that using their preferred Ego functions. i think people take Id block information seriously to an extent, but not to the point where it will override the Ego block.
the Ignoring function, while "strong", clashes directly with the preferred Base function, so people try to to limit its use when dealing with others. this may manifest in someone attempting to shut down someone else who is "pushing" that kind of information too much - literally trying to "ignore" it. the information is viewed as irrelevant, unimportant, and/or superfluous relative to the Base function.
for example, as an IEI, my Base function is
, and my Ignoring function is
. i find that in any given situation, an IEE or ILE will often treat many potential outcomes as if they were all equally likely to happen, and act on this. as an
dominant, i find this a waste to think about, because my
knows what outcome/s is the most likely to actually happen. because my
is strong, i know that other possibilities do exist, but my
overrides this information enough to the point where i don't take it as seriously as the
dominant. therefore, i "ignore" the unlikely outcomes, and act according to the information from my preferred/valued Base function.
