titanium Neclace

| 1 Comment

One product that is being marketed very heavily to people, especially athletes is titanium necklaces and bracelets. The necklaces and bracelets are supposed to be able to boost athletes' performance. The way they work is that the titanium in the necklace is supposed to react with the electric flow in your body and make commutation within nerves more fluid. Because of these necklaces athletes believe they can stay fresh longer and that they can recover quicker. I think it seems impractical for such a little thing to be able to improve performance. If you look at the testing techniques you can see where they went wrong. One would be the scientific principle of correlation vs. causation. When the necklaces and wristbands were originally being tested the test subjects first attempted to complete an obstacle test without the wristbands or necklaces. On the second try the test subjects wore the necklaces and wristbands and completed the course quicker. The company concluded that when wearing the necklace athletes were able to perform better. The company had a confirmation bias because when they got the results they wanted and they accepted them. They should have asked themselves if wearing the necklaces or the wristbands were the true cause of the athletes were performing better. A study done UW-L proves that the necklace company had it wrong in their studies. UW-L had a group with the titanium necklaces and a group with non-titanium necklaces on. Their results concluded that no matter what necklace or bracelet an athlete had on they performed better on the second test because they knew what to expect.
