Daylight Savings Time and "Cyberloafing"

New research suggests that people "cyberloaf" (i.e. websurf instead of working) more when they are tired. Some people may find this surprising. (We do not.) If nothing else, this is another argument against Daylight Savings Time. As the BPS Research Digest explains:

The investigators recognised an event that affects everyone's sleep: when the clocks go forward for Daylight Saving Time. Prior evidence suggests we lose on average 40 minutes of sleep per night following the switch, as our body rhythms struggle to adjust.

Because Parenting Is Hard Enough on Its Own

We've blogged before about the limits of willpower, the idea that "willpower itself is inherently limited." A new essay by Sendhil Mullainathan and Saugato Datta speculates on the role of parents' willpower limitations, particularly with respect to low-income parents:  

Good parenting requires psychic resources. Complex decisions must be made. Sacrifices must be made in the moment. This is hard for anyone, whatever their income: we all have limited reserves of self-control, and attention and other psychic resources. ...

The Authors of Willpower Answer Your Questions

Last week, we solicited your questions for John Tierney and Roy Baumeister, authors of the new book Willpower: Rediscovering the Greatest Human Strength . You responded with a variety of interesting questions, and now Tierney and Baumeister return with some in-depth answers.

Thanks to everyone for participating.


Q. Is willpower a single commodity (so to speak), or is there, as I suspect, a one type of willpower for, say, dieting, another one for academic study, another for this, another for that? -AaronS

There’s one source of mental energy for resisting temptation and performing other acts of self-control, and this willpower is also depleted by making decisions. What you experience may reflect the fact that willpower is limited and so people have to allocate it: they use it at the office to work effectively and diligently, but have messy homes and are short-tempered in the evening. Or people who show wonderful self-control at dealing with personal relationships but can’t seem to meet their deadlines.
