‘The story: Quiet contemplation is so awful that when deprived of the distractions of noise, crowds or smart phones, a bunch of students would rather give themselves electric shocks than sit and think.

What they actually did: Psychologists from the universities of Virginia and Harvard in the US carried out a series of 11 studies in which participants – including students and non-students – were left in an unadorned room for six to 15 minutes and asked to “spend time entertaining themselves with their thoughts.” Both groups, and men and women equally, were unable to enjoy this task. Most said they found it difficult to concentrate and that their minds wandered.

In one of the studies, participants were given the option to give themselves an electric shock, for no given reason or reward. Many did, including the majority of male participants, despite the fact that the vast majority of participants had previously rated the shocks as unpleasant and said they would pay to avoid them.

How plausible is this? This is a clever, provocative piece of research. The results are almost certainly reliable; the authors, some of whom are extremely distinguished, discovered in the 11 studies the same basic effect – namely, that being asked to sit and think wasn’t enjoyable. The data from the studies is also freely available, so there’s no chance of statistical jiggery-pokery. This is a real effect. The questions, then, are over what exactly the finding means.’ (Mind Hacks).
