Before you can make a choice between options you must generate the option set. You asked about the desserts that are available. You collect a bunch of books, on hiking trails at Amazon. Even when you're doing something like walking, there's a pattern of looking around to collect the option set of directions to walk in. Maybe doing basic things like avoiding trees, more sophisticated things like looking for directions to walk that will lead you to high ground where you can see your enemy approach. In this thing, the thing to note is this generation of the option set is the bigger choice part a choice. It's the part where you narrow from infinite possibilities to a few. It's a part of choice. It's guided by an attentional policy.
