Throughout 2007, we tracked over 3000 people attempting to achieve a range of resolutions, including losing weight, visiting the gym, quitting smoking, and drinking less.
At the start of the study, 52% of participants were confident of success. One year later, only 12% actually achieved their goal. The study uncovered why so many people fail, and what can be done to help ensure success.
During the experiment, people were randomly placed into one of several groups, and asked to follow different advice. Large differences emerged between the approaches that best suited men and woman.
