I found this article very interesting, because I for one carry a good luck charm with me at all times. The most interesting this i found from this article is the difference in nerves between people who considered themselves luck to those who considered themselves unlucky. A way to look at this is people make their own luck by making the most of the current situation, while the unlucky are far to nervous to take advantage of the situation.
The other interesting part of Wiseman's article was the effect that people felt that lucky charms had on them because I have carried one for almost my entire life, and very rarly if ever have it away from me. What I found interesting was that people found no positive difference in holding the charm as compared to when they were not holding the charm. The oposite effect was far more likely and people felt that the charm had been bringing bad luck if it was bringing any luck at all and were relieved when they could return the charm and no longer had to wear it.
