While life’s biggest mysteries are the most obvious targets for world-editing, let’s not forget to consider some of the small questions people neglect to ask because they think they know the answers. Take advantage of the “monster under the bed” effect – enigmas lurk in unwatched and unexamined places. That one house on the corner whose inhabitants you’ve never seen. Those weird symbols on money. The timing of traffic lights. The camera that’s pointed at you right now.
