The author questions whether holding a remote control to your head actually improves its functionality, criticizing the poorly designed experiment that only samples instances where the remote wasn’t working without the head involved. They suggest that this is a clear case of selection bias and argues that just because the remote starts working after putting it near your head doesn’t mean it’s actually better. The author mentions a common flaw in human reasoning where people attribute success to rituals instead of realizing it was due to an unrelated system disturbance or another trial. They also mention a similar superstition involving blowing into NES game cartridges. The author acknowledges the possibility that the head may affect the remote’s range due to inductive and capacitive coupling, but emphasizes the lack of proper research and data from qualified engineers to support any conclusions.
