Happy New Year!
Have you made any new year’s resolutions this year?
Despite the high failure rate of these resolutions – research by British psychologist Richard Wiseman in 2007 has shown that 88% of all resolutions end in failure – many continue to make the same resolutions year in and year out.
But just why are our old habit so hard to break?
The Science of Willpower
The brain area largely responsible for willpower is the prefrontal cortex (located just behind the forehead). This area of the brain is also in charge of keeping us focused, handling short-term memory and solving abstract problems.
Author Johan Lehrer writing in the Wall Street Journal proposed that adding new year’s resolutions to an overloaded prefrontal cortex is a sure-fire recipe for failure.
He referred to an experiment led by Baba Shiv at Stanford University, where several dozen undergraduates were divided into two groups. One group was given a two-digit number to remember, while the second group was given a seven-digit number. Then they were told to walk down the hall, where they were presented with two different snack options: a slice of chocolate cake or a bowl of fruit salad.
What do you think happened?
The students with seven digits to remember were nearly twice as likely to choose the cake as students given two digits. The reason, according to Prof. Shiv, is that those extra numbers took up valuable space in the brain—they were a “cognitive load”—making it that much harder to resist a decadent dessert. In other words, willpower is so weak, and the prefrontal cortex is so overtaxed, that all it takes is five extra bits of information before the brain starts to give in to temptation. “A tired brain, preoccupied with its problems, is going to struggle to resist what it wants, even when what it wants isn’t what we need.” writes Lehrer.
So instead of blaming our own lack of discipline in not keeping to our resolutions, perhaps this research shows that the power of will is not enough due to the very nature of the brain.
So now we know what doesn’t work when it comes to keeping those resolutions, let’s take a look at what might help.
How To Keep New Year’s Resolutions
Lehrer suggests we think of willpower as a muscle that needs to be strengthened. Prof Roy Baumeister, a psychologist at Florida State University who has pioneered the muscle metaphor, suggests that it might be possible to strengthen willpower by exercising it.
He asked a group of students to improve their posture for two weeks, thereby practicing mental discipline in one area. The students showed a marked improvement on subsequent measures of self-control, at least when compared to a group that didn’t work on posture control.
If this sounds like too much hard work, you could always try the tried and tested goal-setting approach to making positive change stick.
Think about some small changes you could make in your lifestyle that would help to bring about your ultimate goal. The cumulative impact of a modest change to your daily routine will restore in you the feeling that you are in control.
Above all, don’t use your resolutions as a stick to beat yourself with. Ditch the negative connotations and instead focus on what those small changes will bring to your life in a positive way in the coming year.
