Self-Opinion Function Block of IJ Types (Si-Ni)

These types aim to showcase their stamina and tolerance. They often talk about their appetite and demonstrate their high threshold for physical sensations: enduring hunger, cold, pain, or fatigue for extended periods, or consuming unappealing food.

They may also boast about their sexual experience and the number of partners they have had.

These types tend to emphasize their busyness and workload, or their ability to wait for a long time. They recount how excitingly they spent their past time or how fascinating and rich their current life is.

They strive to highlight their punctuality—often to the point of seeming principled (though this punctuality is usually driven by self-pride rather than principle). Alternatively, they may stress how long they are capable of being alone.
