You wanna be able to tell your friends, hey, my alternative hypothesis, it actually is suggested. We can reject the assumption, the status quo. I found something that actually makes a difference. And so it's very tempting for a researcher to calculate your p-values and then say, oh, well, maybe no one will notice if I then set my significance values so that it's just high enough so that I can reject my null hypothesis. If you did that, that would be very unethical. In future videos, we'll start thinking about the question of, okay, if I'm doing it ahead of time, if I'm setting my significance level ahead of time, how do I decide to set the threshold? When should it be 1 100th?
