Information Elements are "noticed", not utilitized, that is true. They are areas of interest, not cognitive functions. However, you are taking note of an aspect of reality... and then utilitizing that awareness... so in a roundabout way you use IE. She truncated her explaination.

Anyway, information elements come into our active awareness in a compound form - the valued ring and so on, - so it would be best to discuss the IE in a compound form. That said, we should discuss Fi/Fe by quarta. That would be more precise, then draw out (distill) the essence of each accordingly.
