Lefties: Intelligent, forgetful and doomed

Left-handers more ‘creative but forgetful’

An American scientist has gathered new evidence on the link between left-handedness and intellectual creativity, confirming that “true left-handers” tend to be more intelligent and eloquent than right-handers, and better at solving problems.

Dr Alan Searleman, from St Lawrence University, New York, presenting his findings to the American Psychological Association’s annual conference, said: “Left-handers have a higher ‘fluid’ intelligence and better vocabulary than the majority of the population. This is perhaps why there are more of them in creative professions, such as music, art and writing.”

Dr Searleman says that people who throw balls with their left hands, use their left eyes to look through peepholes and place their left ears against the wall to eavesdrop on conversations are twice as good at problem-solving and have wider vocabularies than their right-handed peers.

He enlisted 1,200 people formemory, vocabulary and problem-solving tests. They were asked questions including: Do you hold a match while striking it with your right or left hand? Which ear do you use to listen to another person’s heartbeat?Which eye do you use to look into a dark bottle to see how full it is? He found that people who were “true left-handers”, who did everything on their left side, from kicking a football to picking up a glass of water, scored one-third more highly on vocabulary tests and twice as well on problem-solving tasks.

The research also found that more left-handed people were intellectually gifted, with IQs over 140, Dr Searleman said.

On the downside, left-handers were not so good at remembering things. “Although left-handed people had poorer memories they were twice as good at all the problem-solving tasks,” he said.

Despite the fact that one in 10 people is left-handed, it was once seen as a sign of the devil. The word “sinister” means “left” in Latin. Youngsters used to have their left hands tied behind their backs by teachers to force them to write with their right hands. Left-handed people have struggled for years in a world of right-handed sports equipment and items such as steak knives, cheque books and pairs of scissors.

Previous research has suggested that left-handed people are less ticklish than right-handed people, are more clumsy, and have a shorter lifespan. (The Independent)

Can I be a shaman?

Researchers say they have located the world’s oldest stash of marijuana, in a tomb in a remote part of China.

The cache of cannabis is about 2,700 years old and was clearly “cultivated for psychoactive purposes,” rather than as fibre for clothing or as food, says a research paper in the Journal of Experimental Botany.

The 789 grams of dried cannabis was buried alongside a light-haired, blue-eyed Caucasian man, likely a shaman of the Gushi culture, near Turpan in northwestern China.  The extremely dry conditions and alkaline soil acted as preservatives, allowing a team of scientists to carefully analyze the stash, which still looked green though it had lost its distinctive odour.

“To our knowledge, these investigations provide the oldest documentation of cannabis as a pharmacologically active agent,” says the newly published paper, whose lead author was American neurologist Dr.  Ethan B.  Russo.

Remnants of cannabis have been found in ancient Egypt and other sites, and the substance has been referred to by authors such as the Greek historian Herodotus.  But the tomb stash is the oldest so far that could be thoroughly tested for its properties.

The 18 researchers, most of them based in China, subjected the cannabis to a battery of tests, including carbon dating and genetic analysis.  Scientists also tried to germinate 100 of the seeds found in the cache, without success.

The marijuana was found to have a relatively high content of THC, the main active ingredient in cannabis, but the sample was too old to determine a precise percentage.

Researchers also could not determine whether the cannabis was smoked or ingested, as there were no pipes or other clues in the tomb of the shaman, who was about 45 years old.  The large cache was contained in a leather basket and in a wooden bowl, and was likely meant to be used by the shaman in the afterlife.

“This materially is unequivocally cannabis, and no material has previously had this degree of analysis possible,” Russo said in an interview from Missoula, Mont.

“It was common practice in burials to provide materials needed for the afterlife.  No hemp or seeds were provided for fabric or food.  Rather, cannabis as medicine or for visionary purposes was supplied.”  (NORML.org)

Good vs. Evil…according to a geek

Though I usually try to avoid using the term “evil”, in this context it seems appropriate. So what do you think? Accurate, inaccurate? Do you have suggestions for either side this geek missed? Bring them on.
