Late sleepers are more intelligent?

Ran across an article saying that people in their 20's who sleep later on average are smarter than those who go to bed early. What are your guys thoughts?

Very Dull (IQ 75) Weekday: 11:41 P.M.-7:20 A.M. Weekend: 12:35 A.M.-10:09 A.M.

Normal (90 IQ 110) Weekday: 12:10 A.M.-7:32 A.M. Weekend: 1:13 A.M.-10:14 A.M.

Very Bright (IQ > 125) Weekday: 12:29 A.M.-7:52 A.M. Weekend: 1:44 A.M.-11:07 A.M.

Spurious correlation? Statistical significance vs. practical significance? Population statistics vs. sample statistics (sometimes there might be a correlation between two variables in a sample, even though there's no correlation between them in a population)?

 

In Mensa already. Just got in, 3AM on a weekend.

By the way, its not an award, its an organization.

looking for that pick-me-up to power through an all-nighter?
 

Most likely people with high iq have jobs that allow them a little flexibility/don't require them to punch their time card at a precise time. Also, people in their 20's probably have hard time going to bed by 10 pm and waking up at 5 am on the regular, like older people can, mainly due to late-night social life. So it would be safe to assume that all younger people would prefer a schedule that allows them to come to work later, leave later, and stay out later, but the people with lower IQ don't generally have their pick of careers to where they dictate what time they are gonna show up, and thus they take the jobs that require them to be at work by 6-7 am. There's no f-ing way I would take a job requiring me to be at work that early (regularly), not even for a significant pay increase.

Equity derivatives trading - 6:30 am start, you have to love it to do it day in day out lol

You must have inevitably attained killer work ethic and discipline through the process.

Wow, this is great to hear! And all this time, I thought my partying ways would end up hampering my GPA for this MBA program. For me, it's usually about 2 on weekdays, where i'm up by about 7:30 and on weekends, I usually sleep around the same time, but don't wake up before 10:30.

 

Another probable correlation is that smarter people go to school at that age, and the not so smart people go to stock shelves at walmart. I highly doubt that any of my coworkers that have to get up at 6 to get their kids ready for school are in any way dumb.

Similarly, if someone used to get up at 10, but now gets up at 6 due to changing circumstances, such as kids or a new job, I doubt their IQ would change. How to Lie with Statistics.

 

to all the posters i know that this doesn't obviously make you smart by sleeping later but its definitely an interesting observation / study and has been repeated many times (try googling it). If you guys skimmed the articles they note that most of it is probably do to social/job factors and that people with less IQ are more likely to be out working a job during daytime (earlier) or have less active social lives.

Take it like a nice Snapple fact.

You must be pretty dumb...

To be fair I woke up at 2pm yesterday, so I must be a complete retard.

That's interesting. If that were a fact, then I'm considered a genius. I sleep past 1 am almost every night!

 

Damn, you guys sleep in late during the week.

weekday: 2am - 6am weekend: 4am - 12pm

The data is obvious. A 21 year old is much smarter than a 29 year old (test taking wise). There's a certain point where your mind just goes down hill.

 

Y'all have some fucked up sleep schedules

I'm usually: 12:00 AM - 7:30 AM on weekdays 2:00 AM - 10:00 AM on weekends (Sometimes I'll stay out later than 2 but I'll always wake up around the same time)

College was basically the same thing
