Foray’s third condition for combinability is clarity of the knowledge shared. We communicate instructions about cooking in recipe form for a reason: by listing ingredients and ordering instructions in steps, a recipe is clearer than a purely narrative description of how to cook a dish. A rambling description might have the same informational content as a recipe, but the form of a recipe is clearer. As a result, once any field of endeavor acquires something like a recipe–a set of instructions for an activity, separable from the activity itself–it can circulate much more effectively among people who can understand it.
