You can't use statistical evidence to invalidate someone's personal experience. It doesn't work that way! When someone says that a standing desk has helped them, you can't just jump out and say "aha! this study says on average they don't work, therefore that someone is rationalising their purchase". The best you can say is that it works for some people and not others.
