Well that was dogmatic given the context here. I'm not talking with scientists, about actual science. I'm playing "Bill Nye" here.
If I'm talking to scientists, about science, I don't have to mention that a single trial doesn't mean much.
Given the state of science education and reporting, it is often more important to repeat some of the basic things, rather than less. Otherwise we get people thinking that Mythbusters is how normal experimental science is done.
