I work for the control group at another accelerator, so we were visiting and meeting their control guys. Super friendly people all of them, they treated us like kings... and their control centre is bigger than our whole facility xD

So they allowed you to know that you are in the control group? Doesn't that introduce bias ;)

Sorry, I don't understand your comment :/

He was referring that in many experiments (especially in medical/biological) you usually have a control group, e.g. the group that is being given a placebo.

Took me a moment to understand it as well :)

Ah shit, you are right. I worked at a medical research center aeons ago so I should have known, but I am still dizzy from the jet lag xD
