All right, now let's do this together. A group of doctors was interested in comparing the effectiveness of placebo pills and real pills in treating migraines. And placebo pills are pills that look just like the regular pill, and from a patient's point of view, they don't know which one they're getting. And the reason why we do this in studies is because there's something called the placebo effect. Oftentimes, just by taking something that you think is good for you, some medicine that you think might help you, it actually does help you. And we can think about why the placebo effect happens, but this is well-documented. And so when people are trying to test medicine, they wanna say, well, does this have an effect above and beyond the placebo effect?
