Sure. So cohort data, you're comparing groups, but you're not having an intervention. So you're tracking them over the course of however, what period of time. A lot of cohort studies like looking at cardiovascular disease, cancer.

Those are some of the classic experiments, right?

And you look at, okay, over 10 years, over 20 years, who gets whatever more often or less often, right? And then we try to figure out and calculate, okay, what's the effect and is this real? The problem is you have a lot of bias with those sorts of studies, meaning people don't do single habits. They don't isolate habits.

I actually put up a reel the other day from my appearance on Stephen Bartlett's podcast where he said, if I want to fix my diet, I go to the gym. Because a lot of people do that. If they're training in the gym, they don't want to waste their effort by having a subpar diet. Now, in reality, eating a healthy diet is more important if you're not going to the gym, right?

Because at least you're getting something. But people do this habit coupling. And so it's really hard to disentangle those sorts of things. Now, the reason that human randomized control trials are important is if you're designing an experiment and you randomize What you are doing by randomly assigning people to groups, you're washing out that bias because.

you can assume that whatever inherent characteristics that might be coupled to whatever you're going to try are going to be randomly distributed and evenly distributed across the groups.

Therefore, we say human randomized control trials are kind of what's needed to establish causation because by randomizing, you can assume whatever differences are observed between the groups are due to your treatment and not due to random chance or data artifacts. Now,
