Email or Marijuana which is worse on Productivity?

Sooner or later when you talk about productivity or doing things better the subject of email comes up. How much time do you spend looking at emails? Back in the early days of the internet it used to be fun to get email, remember the movie ‘You’ve got Mail? What with spam these days and people cc’ing everyone on everything email often becomes quite a burden.

You've got mail!

Now to answer the email vs marijuana question; back in 2005 a psychiatrist at King’s College in London did a study that administered IQ tests to three different groups: the first group just performed the IQ test, the second group was distracted by email and ringing phones, and the third was stoned on marijuana.

 It was no surprise the first group outperformed the other two by an average of ten points. What was surprising was the email/ringing phone group did worse than the stoners by six points.

 “Workers distracted by email and phone calls suffer a fall in IQ more than twice that found in marijuana smokers, new research has claimed.”

 The disruption of a task at hand can take up to 45 minutes until you ‘get back on track’. It is like there is a certain amount of cognitive momentum that is lost and takes time to regain.

 I found this information on The author Leevi Romanik suggests not only should we be aware of our habits (because that in itself can help improve things) he also suggests we can improve our ability to focus.

If you are interested check out my article  for a few tips on how to approach email differently. I also recommend five sentences as a great email policy.

 Productivity is a measure of how much – work, time, effort, money, or energy – you have to put into something to get the desired outcome. For more tips and tools on how to get more productive please visit Blue Collar Consulting Inc. at
