The Mere Measurement Effect  describes the tendancy of asking someone’s intent to do something increases the likelihood of them doing it. For example, people were asked if they intended on purchasing a car in the next six month increased the likelyhood of actually buying a car by 35 percent. Asking someone if they intend to vote causes similar increases in actual voting participation. 
You can use this tendancy to your own benefit by asking yourself – and answering – do you really intend on doing what ever your goal is. For example, do you intend on losing weight. Do you intend on making the phone calls necessary to make your business successful. Simply ask yourself.
