 placebo control. Placebos. So placebo gets a sugar pill. It doesn't have to be a sugar pill. It can be any type of, I don't know, it's hard to say. I'm going to read this. No, I don't like that either. So placebo control, we're going to do something to prevent the subject from knowing what condition they're in by giving them something, right? So Brad told me he was giving me alcohol this morning. He was told me he was giving me vodka. So I don't know if I believe him or not, but I drank a lot of it. So it's kind of a placebo control, not really, right? So he actually gave me water. So if he flavored this to make it taste a little bit like vodka, then that would be like a placebo. So okay, we're going to find out what the effect of vodka really is by giving someone something that's similar to vodka and giving them vodka, right? So in another condition. So then we can make that comparison. The idea is, is that if we give them the placebo, then we are creating the expectancy effect. If you do not give the placebo, then you're not getting the expectancy effect. And when you do the intervention, so with the vodka, you will get an expectancy effect that goes along with it. So we want to neutralize that expectancy effect by giving a placebo control. There's lots of ways you can do this. So we can talk for days or not.
