If a person latches on to a temporary feeling as true, then they will be disappointed when the person who has this feeling eventually rejects it in favor of a deeper, time-transient feeling. (like rapport) The pain of the disappointment is a reminder not to use as base. The same goes for : if an INTj believes a collective feeling experience will last, then they will be disappointed unless they receive additional direction from ESFj, who *knows* what is not only popular, but indeed what will *remain* popular. It is our disappointments that create the subjective impetus to put our strong elements before our weak elements. However, the disappointments all owe to people who use our weak elements strongly. (I've learned this from painful experience.)
