Steve Hardy has written an article – What Specifically Do Generalists Do? To quote:

All the elements that make up experiences are very complex when viewed objectively … but since experience is subjective, it is wonderfully refreshing and most useful to look at that kind of complexity through a human subjective lens and ask simply “what does the experience feel like from this perspective?”. Literally seeking to understand the experience, the journey through time and space, for someone else. That perspective automatically integrates all the contributing elements into a whole and helps you appreciate the interdependencies in a way that doing only objective analysis wouldn’t.

This is the most succinct–and perhaps the best–description of complexity I’ve come across. It captures the essence of what we are trying to do in our narrative projects.
