Like flowing water, people will often take the path of least resistance. If there are two or more options, a “default” provides a predetermined path for people to follow if nothing is specifically decided (Thaler & Sunstein, 2008). For example, chainsaws are now sold with a deadman switch, stopping the dangerous machine when you are no longer gripping it. A more everyday example would be when you leave your phone or computer for a while, and the screen locks. Of course you are free to change this by diving into Settings and making changes, but how many of us do?
