Say you run a summer camp for kids. Goal: you want all the kids to stay hydrated. Your options are 1) to have set times when everyone has to lineup to get a water bottle, or 2) have a bunch of water bottles available at all times for anyone to come take when they want. Option 2 works pretty well since kids know when they are thirsty. (Obviously. Otherwise the kids would all die of thirst under option 1 as well) A strange phenomenon emerges however when you start with option 1 and then halfway through the summer another counselor attempts to implement option 2. The kids have been preconditioned to expect that they NEED to get a bottle when the bottles are available or they won't have access to water later. It takes some time for the kids to figure out that the waterbottles are now available at all times and they don't need to carry one around all the time "just in case". Till then you have a small riot around the cases of water bottles for a few mornings. Option 2 distributes the water in a more efficient manner. The kids who spend time playing soccer will take more water than the kids who stay inside playing chess. This is my own experience as that other counselor. You can work out the analogy, I'm sure.
