"Compared to students who reported sleeping eight hours at night, high school students who slept less than six hours were twice as likely to self-report using alcohol, tobacco, marijuana or other drugs, and driving after drinking alcohol. They were also nearly twice as likely to report carrying a weapon or being in a fight. Researchers found the strongest associations were related to mood and self- harm. Those who slept less than six hours were more than three times as likely to consider or attempt suicide, and four times as likely to attempt suicide, resulting in treatment. Only 30 percent of the students in the study reported averaging more than eight hours of sleep on school nights."
Seems like a lot of data mining to create correlations (hence the use of the word "association" a lot). This kind of work can be good for problem finding and hypothesis generation. It's unfortunate that we live in a world where:
- news outlets publish research that is meant to stimulate discussion + hypothesis exploration
- readers are unable, undereducated, and / or disempowered to discern the level of rigorous science examination done
EDIT: The funny thing is that I predict that this HN thread will lead hundreds of folks to tell stories of confirmation bias.
