I chose to change the magnets on the front of the dishwasher for my nudge. My hope was that the change would highlight the need for people to unload the dishwasher. I chose a yellow and black color scheme for high visibility.
Preliminary results are promising. On my first day of observation students did unload the dishwasher more quickly and as a result there was no crunch at 3pm. Everyone was able to put their dishes in the dishwasher right away. Results were less promising on the second day, George unloaded the dishwasher.
An interesting unexpected behavior, people seem willing to move the magnet into the ‘Unload’ section if they see the dishwasher needs to be unloaded but do not have the time to unload it themselves.
