Oh. Twice as much. That's a lot, right? We could be moving from 1% to 2% here. Technically true, but statistically meaningless. So while we could say that a teen who engages in risky behavior is less likely to have adequate sleep, we can't say that a teen that has inadequate sleep is likely to engage in risky behavior. And if we're looking to identify teens likely to engage in risky behavior, it's useless. And there are other things to consider as well. The study was done with 67,615 participants. 70% who are sleep-deprived compared to 30% who are "well-rested". The population of "sleep-deprived" is much, much larger. Also, we're looking at self-reporting. A bit unreliable in the best conditions. And we're drawing a casual link here that may not actually exist. They both may be symptoms of a third problem. For instance, students in impoverished conditions may have more risky behavior regardless of sleep schedules. And if that was the real reason, forcing more sleep on people is hardly going to fix the problem.
