Eventually, my wife got home somehow, only to find her mother lost in research on the bald eagle. While the story is funny, this sort of thing happens to the INFJ a lot, and it’s a consequence of the introverted intuition which is an information gathering function. An INFJ can easily spend two, three, or four hours researching a topic of interest. INFJs get so caught up in what they’re doing that they lose track of time and may even neglect their basic needs. They’ll forget to eat or drink or to use the bathroom until all of the sudden they realize they’re starving or they’ve got to run.
