And so when people are trying to test medicine, they wanna say, well, does this have an effect above and beyond the placebo effect? And so that's why they are putting them in these two, that's why they're comparing the real pills to the placebo pills. So they randomly assigned a group of 300 patients suffering from migraines into two groups. So they have their 300, they have their 300 patients right over here, and they're randomly putting them into the placebo group, placebo group, or the real, or the real pill group. One group was given a real pill, oh, we already read that. Both groups were told which kind of pill they got. That is sketchy, because the whole point about a placebo is that you think you got the real thing, or you think you might have gotten the real thing, and if you're told you got a placebo, that tends to undermine the placebo effect.
