Isn't this why there is such a bandwidth bottleneck when trying to make tacit knowledge explicit. You can only really have a "tacit" exchange between two like-minded experts, where most of the learning is subtext, anyway. ( I use the example of Picasso studying Velasquez' "Las Meninas").

What I was thinking of in my comment above is about how much the expert chooses to explain to a journeyman, novice or outsider when the context and caveats require a lifetime of experience to comprehend.

Then there is also the problem of available time, which people are starting to recognize as an issue in collaboration. The longer that learning conversation takes, the less time there is for the doing, eh?
