True, the article does specifically say people spent time doing nothing, and just thinking.
But this shocks me:
The researchers then decided to take the experiment a step further. For 15 minutes, the team left participants alone in a lab room in which they could push a button and shock themselves if they wanted to. The results were startling: Even though all participants had previously stated that they would pay money to avoid being shocked with electricity, 67% of men and 25% of women chose to inflict it on themselves rather than just sit there quietly and think, the team reports online today in Science.
Really a wtf moment for me. I take from this that most people think it's painful to meditate as well, because that's reflecting on your thoughts.
