placebo effect

Former neurosurgeon Prof Richard Nelson, who led the development of the Institute of Clinical Neurosciences in Bristol, said the "placebo effect" rarely accounts for 90% of results.

But he wonders how often the treatment might cause a placebo effect.

Despite anecdotal evidence from some of the world’s best athletes, it’s natural to wonder if it’s just a placebo effect or if there’s real science to support this wellness.

The power of a psychological placebo effect, especially as it relates to sports — and on a global stage like the Olympics — cannot be underestimated.

However, these anecdotal accounts can often be influenced by the placebo effect.
