I was on The Takeaway this morning talking about the ineffectiveness of Human Growth Hormone (HGH) and the potency of the placebo effect. Even though most studies demonstrate that HGH does little to enhance athletic performance, world class athletes continue to take the banned hormone. Why? Because they’re convinced that HGH is effective. As a result, the drug gives them a mental edge – because athletes expect to perform better, they do perform better. The illusion of an advantage, if it’s sincerely believed, can be a real advantage.
