 Informed consent. To be honest with you, you should have watched this before you watched any of our other videos. Why? In fact, I think I'm going to make you. Why? Because then you'll be informed and you'll be able to give you your consent to continue to watch these videos. You'll understand what these videos are about. You'll understand what you'll see. You'll understand what you'll hear. You'll understand that we're quite irreverent. We get naughty and we are hopefully, huh, funny and maybe smart. Hopefully we just help you. That's really all we're after. But anyway, informed consent is about giving you an understanding about what you're ready to experience, either an experiment or something else, so you can make an informed decision about whether or not you want to continue. We can look at the Tuskegee experiments. We can to show an example of not informed consent. You can look at all sorts of things throughout history about not having informed consent. How about the HeLa cells? H low E capital L small a. Take a look at that book. Great stuff. Henrietta Lacks, right? So informed consent is about making sure that the people that are participating that you're working with understand what's about to happen to them and can make a decision accordingly about whether or not they choose to continue with the experiment or the treatment.
