Prototyping Reality in Your Brain

Once you've got a whole bunch of possibilities on the table then you start to narrow it down and engage a different part of your brain. So instead of divergent thought coming up with as many divergent ideas as possible we're not going to converge but rather narrow the field so that we can give more careful consideration to the ideas that seem to have more potential in them. The more accurately you can replicate reality with your mind the better you can prototype things with your brain like and test different possibilities.
