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

    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
