In science, it's not enough to think something is so. Researchers must show that what we believe to be true is in fact true, proven through statistically significant and reproducible results. Questioning assumptions is, after all, what science is about.
Nonetheless, some studies really take the cake in the "duh" department, discovering things that were already obvious. Here are findings from this year that should come as little surprise.
1. Unsafe sex is more likely after drinking
Drinking too much alcohol can impair decision-making. And a study out this year drove this point home: Canadian researchers, reporting results that will be published in January in the journal Addiction, said they ran 12 studies looking at the link between blood alcohol and the likelihood of agreeing to use a condom during sexual intercourse. The more alcohol in a person's system (yes, the drunker they were), the more likely they were to throw caution to the wind and ditch safe sex. Specifically, for every 0.1-milligram-per-milliliter increase in study participants' blood alcohol levels, there was a 5 percent increased likelihood of having unprotected sex.
2. Men appear confident by suppressing fear, pain and empathy
When mixed martial arts fighters need to show off masculine strength and confidence, they suppress fear, empathy, pain and shame.
Yeah, not too shocking: that tamping down those emotions might make someone seem more formidable. But the research, published in December in the journal Social Psychology Quarterly, was aimed at understanding how men manage their emotions and expectations of manhood.
"Managing emotional manhood, whether it occurs in a locker room or board room, at home or the Oval Office, likely plays a key role in maintaining unequal social arrangements," study author Christian Vaccaro of Indiana University of Pennsylvania said in a statement.
3. Smoking pot and driving isn't safe
Who knew, getting behind the wheel while high could be trouble? According to a study published in October in the journal Epidemiologic Reviews, marijuana use increases the risk of car crashes. People who took to the road within three hours of smoking pot, as well as those who tested positive for the drug, were more than twice as likely as other drivers to be involved in a car crash. And that risk increased for those who smoked more frequently and those showing a higher level of the drug in their urine.
4. Pigs love mud
Turns out pigs aren't just putting on a show when they haul butt around their muddy quarters, diving into the muck. They actually like it. While mud baths keep pigs cool, a review of research reported in 2011 found wallowing may also be a swine sign of well-being. While the review found the strongest reason noted in the past studies for wallowing was to keep cool, the pigs kept it up through winter months.
5. Fashion magazines glorify youth
Surprise, surprise: Fashion mags portray women over 40 sparingly, if at all. Young celebrities and models dominate the pages of these publications, even ones targeted at older age groups. For example, researchers reported in April in the Journal of Aging Studies, that 22 percent of the reader base of Essence is older than 50, but only 9 percent of the women in its pages were even older than 40. Vogue featured only one woman over 40 on its covers in 2010: Halle Berry (then 43).
6. People with generous partners have happy marriages
In the realm of unsurprising marriage advice, researchers found this year that generous marriages are happy marriages. Couples with spouses who offer back rubs and other seemingly selfless acts are happier with their relationships than people who report low amounts of generosity in their marriages, according to researchers with the National Marriage Project.
Half of women and nearly half (46 percent) of men who reported above-average generosity in their marriages described themselves as "very happy" with their relationships. In comparison, only 14 percent of people with low levels of generosity in their marriages said the same.
7. Parents don't think their kids are doing drugs
Smoking pot and drinking? Not my daughter! Parents are in denial about their own children's bad habits, according to poll data released in September by the University of Michigan's C.S. Mott Children's Hospital. That study found that while most parents believe at least 60 percent of 10th-graders drink alcohol, only 10 percent thought their own teen did.
8. People aren't doing anything in particular on the Internet
Anyone who has ever gone down an Internet black hole, only to emerge hours (and dozens of Wikipedia articles) later, will be less than shocked at the revelation that online is the place to go for mindless entertainment. According to a Pew Research report released in December, 53 percent of people ages 18 to 29 get online at least once on any given day just to pass the time. Using the Internet to goof off isn't limited just to the young, either: Fifty-eight percent of all adults said they sometimes get on the Internet for no reason other than casual entertainment.
9. Restricting driver's licenses decreases teen fatalities
Graduated licenses, which allow teens more freedom behind the wheel as they gain driving experience, save lives. Researchers at the Institute for Research and Evaluation (PIRE) reported in November that fatal automobile crash rates among 16- and 17-year-olds fell 8 percent to 14 percent in states that enacted graduated-licensing laws. Restrictions such as limits on the number of passengers a teen can ferry around and rules against night driving decreased fatal crashes by 13 percent and 9 percent, respectively. Practice (and a little more maturity) makes perfect, it seems.
10. Most shoppers ignore nutrition labels
Calories, cholesterol, sugar … yawn. A study published in October found that grocery shoppers pay little attention to the information on nutrition labels. Even shoppers who say they "almost always" read nutrition information aren't likely to take in much information in a real-world shopping environment, the research found. Using an eye-tracking device on study volunteers, researchers found that only about 1 percent looked at information about total fat, trans fat, sugar and serving size on nearly all labels, even though between 20 percent and 31 percent of people said they looked at each of those categories when they shopped. Anything low on the label is particularly unlikely to get attention. The study found that the average consumer doesn't make it past the fifth line.
11. Presidents outlive their contemporaries
U.S. presidents tend to live as long or longer than their contemporaries, according to research published Dec. 7 in the Journal of the American Medical Association. Sure, being chief executive is stressful (and eight have died in office, four by assassination), but it turns out the top job in the country comes with perks: great medical care, for example. Presidents also tend to be well-off and well-educated, according to lead researcher S. Jay Olshansky, a professor of public health at the University of Illinois at Chicago. Unsurprisingly, money and knowledge tend to buy health and longevity.

Fun Read!
eh.
Nothing there is science. It's psychology. Psychologists for the most part do nothing more than have a firm grasp of the obvious. Your headline unfortunately will be fodder for the anti-intellectuals.
And how much did it cost us taxpayers for this research?
#1 was Canadian researchers. So that's not applicable.
#2, #3, #5, #6, #7, #10, and #11 were academic institutions. They may have gotten a small grant from the government typically worth tens of thousands at most. They may not have gotten any grant from anybody for their research.
#4 was a literature review, which didn't require any money since it presented no new information.
#8 and #9 were private institutions.
In other words, at most this cost the taxpayer about what it takes to run government for less than a second.
DUH!!
No--this is not "duh." There are plenty of people who argue that marijuana does not inhibit people's ability to drive (in fact, there was a "study" done by a pro-marijuana group to "prove" it). There are also people who argue that getting drunk decreases a male's ability to have sex, and so sex is less likely after drinking--they therefore argue that risky sex is also less likely after drinking. There was also a study done which showed that pigs were tidy animals if kept in an environment which was not too hot or dry. Studies like this are good to do in any case, because every now and then, we do find out that "common knowledge" is dead wrong.
"Common sense isn't so common" I can't believe I read this article.
#3... I guess they have a lot more accidents at under 10 miles per hour...
And yet, you still need to be able to show why the obvious is true. Just because it seems to be true doesn't mean it actually is nor does it mean you understand why it is true. This sort of study is important even if it seems trivial because by having an understanding of the way things are, it can guide to understand why they are that way. And if we can understand why, we can develop policy to account for it.
For example, driving while high isn't a good idea. Great, but what does that mean? How does driving after having taken marijuana compare to other impairments to functioning? From the short description, it appears that the impairment lasts for hours afterward and appears to be a cumulative effect. Compare this to alcohol where the metabolism goes at a different rate. If we were to ever legalize marijuana to the same class of substance as alcohol, we will need to determine what constitutes an illegal level of impairment.
You can't know what to do with information until you know it and can show your work as to why. "It's obvious" is never sufficient.
Marijuana users as a whole are more willing to take risks. This could explain higher accident rates for those not currently high but with traces in their urine. BTW, I drive better when I'm high.
Eat,
You only think you drive better while you're high. That's the whole impaired judgement thing at work. I had a roommate in college who had been in more than one wreck at the age of 24. He was a major stoner. When I asked him why he thought he'd been in so many wrecks, he said "I dunno man, I guess I'm just unlucky." At his age, I'd never been involved in a fender bender, nevermind a wreck.
It is actually rather frightening to think that this gentleman thinks he drives better when he is high--if he is right, then how badly does he drive when he is not stoned? Really frightening.
I NEED HELP. my son has a brain injury he was in a deep coma for 7 weeks then he woke up unable to talk it has been 4 years, now i heard about ambien the sleep aid and how it helped a young man to talk, i have requested the va to prescribe this for my son just to try it and see if it works for him, what i need help with has anyone used this method to help someone they love to wake up this part of their brain? if so how much did you give them and how long did it take to work?
You appear to be posting under the wrong article. There was an interesting article from 2 August 2007 Nature by Nicholas Schiff about deep brain electronic stimulation that seemed helpful. Adrian Owen wrote in the December 2011 Lancet about brains becoming more active when patients were asked to do something (even though they could not obey the command). The Moss Rehabilitation Research Institute in Philadelphia is currently doing the study on zopidem (Ambien). Hope that helps.
MY E MAIL ADDRESS IS AS FOLLOWS dianamasten@gmail.com for the help i need on the ambien sleep aid please someone help my son talk thank you,
I bet most of these studies were sponsored by an organization with an ulterior motive.
I want some of the money these "scientists" get paid to come up with this stuff. I can come up with obvious stuff, and I'm sure a lot of you people could, too. Some scientists seem to need to justify their jobs.
As I thought would happen. they're not scientist, they're psychologists.
Ferrosynthesis--have some fun distinguishing between "scientists" and those who do research on human behavior (yes, they often study "psychology"--but it is human behaviors that they are testing). The scientific method is the same for all, whether they study animals, vegetables, or minerals. Researchers are researchers--and if they are using the scientific method, then they are called scientists. Are you a Scientologist, by any chance (which should not be confused with "science" unless we are discussing "science fiction")?
Medicinal plants, herbs, spices and herbal remedies are known to Ayurveda in India since long times. The value of medicinal plants, herbs and spices as herbal remedies is being lost due to lack of awareness, and deforestation. The result is many valuable medicinal herbs are becoming rare and precious information is lost.

I actually heard the opposite about pot and driving. A study came out this year showing no cognitive impairment for long term users... did they properly control for other factors, such as plain old BAD DRIVING?
