Sweden: The New Laboratory for a Six-Hour Work Day
Six-hour days <i>may</i> be more productive, but this won't prove it one way or the other because:<p>- The people working six hour days have been told that this may improve productivity so the excitement of being part of the experiment may indeed encourage them to be more effective in the short term<p>- They have a strong incentive to work harder because if the experiment concludes that six hour days are more effective, they will likely get to keep working six hour days.
