I'm looking for a word that can be used to describe the amount of knowledge that has been revealed to a person or population.
For example, if I was studying a culture that didn't have access to computers, and I wanted to describe the "level of knowledge" that the population had been exposed to (as opposed to the level of knowledge that they actually had), is there an academic term for describing this concept?
Another example: if I wanted to talk about, how the level of knowledge that a culture had been exposed to was slowly changing traditions around child brides, what word could/should I use to describe the "measure of revelation?"
I considered the word revelation:
1. the act of revealing or disclosing; disclosure.
2. something revealed or disclosed, especially a striking disclosure, as of something not before realized.
However, that particular word has obvious religious connotations, and it is more often used to describe a surprising discovery in my experience.
Honestly, the best phrase I have so far is, "measure of revelation."
