I remember someone saying “mad scientists in fiction aren’t scientists because there’s never a control group”
I think if you’ve created an elixir that turns people into goat men you have sort have gone past the need for a control group. The control group is not going to placebo themselves into goat men. You can probably not run the control group, and safely assume that none of them would have turned into goat men. That said, having a control group for that would make the mad scientist seem extra crazy and be really really funny, especially if he was carefully testing them for goat like features from the dyed water they drank instead of the elixir
