Rolf Dobelli, in a blog post quoted by the Guardian, says that news is bad for you — and giving up reading it will make you. (I personally gave up reading “newspapers” a few years ago – instead news, if important to me, finds me.) You can download Rolf’s essay here.
We are not rational enough to be exposed to the press. Watching an airplane crash on television is going to change your attitude toward that risk, regardless of its real probability. If you think you can compensate with the strength of your own inner contemplation, you are wrong.
