  • Pink is for girls and Blue is for boys?

    It’s so embarrassing when scientists use poorly-constructed studies to blithely reinforce societal stereotypes. Today, LPH at Second Innocence brings us the latest example.

    A new study by scientists from Newcastle University gives substance to the old adage ‘Pink for a girl, blue for a boy’.

    Evolution may have driven women’s preference for pink, according to the study published today.

    ‘The explanation might date back to humans’ hunter-gatherer days, when women were the primary gatherers and would have benefited from an ability to home in on ripe, red fruits. Culture may exploit and compound this natural female preference’, says Professor Anya Hurlbert, Professor of Visual Neuroscience at Newcastle University.

    The study, which is published in the latest issue of Current Biology, provides new scientific evidence in support of the long-held notion that men and women differ when it comes to their favourite colours.

    ‘Although we expected to find gender differences, we were surprised at how robust they were, given the simplicity of our test,’ says Professor Hurlbert.

    LPH points out, this is really dumb for two glaring reasons. First, the pink=girl, blue=boy thing is a relatively new invention:

    “…the generally accepted rule is pink for the boy and blue for the girl. The reason is that pink being a more decided and stronger color is more suitable for the boy, while blue, which is more delicate and dainty, is pertier for the girl.” [Ladies Home Journal, June, 1918]

    Second, it’s just stupid to think you can take 171 brits who have been exposed to this stereotype their entire lives and expect a result to be reflective of some genetic effect. The explanations they come up with are cringe-worthy.

    ‘The explanation might date back to humans’ hunter-gatherer days, when women were the primary gatherers and would have benefited from an ability to home in on ripe, red fruits. Culture may exploit and compound this natural female preference’, says Professor Anya Hurlbert, Professor of Visual Neuroscience at Newcastle University.

    However, Professor Hurlbert says she could only speculate about the universal preference for blue: ‘Here again, I would favour evolutionary arguments. Going back to our ‘savannah’ days, we would have a natural preference for a clear blue sky, because it signalled good weather. Clear blue also signals a good water source’, she says.

    LPH’s response is about right.

    Oh, those savvy homo habilis home makers. You probably use those same red-finding skills in the supermarket today! Well, that settles it. We can, in fact, use preferences formed by a very small, very homogeneous group to explain our genetic gender differences and there will always be someone with the right letters behind their name who is willing to back up even the stupidest stereotype.

    How does this kind of nonsense get published?

  • Skeptics' Circle Number 66 – Summary of Abstracts

    Welcome to the 66th meeting of the International Society of Skeptics.

    Abstracts from attendees:

    Straw Men and Circular Reasoning
    Author: Skeptico
    Introduction The problem of debunking crop circles persists despite many previous valiant efforts (See Sagan, C.S. Demon Haunted World).
    Results In this study the author evaluates current research into the formation of crop circles. Relying on faulty evidence and circular reasoning, current proponents fail to elevate crop circle formation from hoax to alien conspiracy.
    Conclusions Crop circles remain convincing evidence of extraterrestrial life only for people with defective reasoning skills.

  • Again with the Marijuana

    Blogging on Peer-Reviewed Research

    What is it about reporting on pot that makes people so Puritanical? Today I read in the Guardian Cannabis joints damage lungs more than tobacco – study.

    A single cannabis joint may cause as much damage to the lungs as five chain-smoked cigarettes, research has found.

    Is that so? Let’s take a look at the data.

  • Does Smoking Cannabis Cause Schizophrenia?

    Blogging on Peer-Reviewed Research

    A lot of people are talking about a new study showing a 40% increase risk of “psychosis”, which I first heard news of in this story, from the Daily Mail:

    A single joint of cannabis raises the risk of schizophrenia by more than 40 percent, a disturbing study warns.

    The Government-commissioned report has also found that taking the drug regularly more than doubles the risk of serious mental illness.

    Overall, cannabis could be to blame for one in seven cases of schizophrenia and other life-shattering mental illness, the Lancet reports.

    Something sounds a little off. Let’s see what this Lancet study says.

  • I can has souls?

    I couldn’t resist when I read this Guardian story about Oscar, the death predicting cat.

    When the two-year-old grey and white cat curls up next to an elderly resident, staff now realise, this means they are likely to die in the next few hours.

    Such is Oscar’s apparent accuracy – 25 consecutive cases so far – that nurses at the US home now warn family members to rush to a patient’s beside as soon as the cat takes up residence there.

  • The Independent needs its environmental credentials to be taken away

    Between electronic “smog” and their incessant bleating that every weather event is due to global warming, I have come to the conclusion that the Independent, with stories like this one, are trying to bring down the science of global warming from the inside.

    It’s official: the heavier rainfall in Britain is being caused by climate change, a major new scientific study will reveal this week, as the country reels from summer downpours of unprecedented ferocity.

    More intense rainstorms across parts of the northern hemisphere are being generated by man-made global warming, the study has established for the first time ­ an effect which has long been predicted but never before proved.

    The study’s findings will be all the more dramatic for being disclosed as Britain struggles to recover from the phenomenal drenching of the past few days, during which more than a month’s worth of rain fell in a few hours in some places, and floods forced thousands from their homes.

    I feel like Mooney said it best in what I quoted in his book review this morning:

    At the outset, let me offer a critical point of clarification: Global warming did not cause Hurricane Katrina, or any other weather disaster. Or to put it more precisely, we just can’t say scientifically that global warming either does or not “cause” individual weather events.

    Exactly! Will somebody please tell the independent this? Climate change is about increasing probability of certain types of weather. It is not possible or responsible to attribute specific weather events as evidence for or against climate change. These ridiculous assertions from the Independent are just as annoying as those coming from anti-GW cranks like Tim Blair who rejoice in every cold-snap. Climate is not the same as weather!

    What is even more amazing is that in the same article they include this statement:

    The new study, carried out jointly by several national climate research institutes using their supercomputer climate models, including the Hadley Centre of the UK Met Office, does not prove that any one event, including the rain of the past few days in Britain, is climate-change related.

    So why did you just write 10 paragraphs about how it is?

    Jackasses.

  • This is why you should never source Wikipedia

    So, who has heard of the Rife Machine? It is a quack device that purports to destroy diseases by homing in on their resonant frequency, and disrupting them with radiofrequency (RF) waves (like a soundwave shattering a wine glass). I’ve met true believers of this stuff before, and there is little you can do to dissuade them of the magical power of these machines, that when dissected reveal they’re little more than batteries with flashing LED-lights – and no capability of generating specific radio frequencies. I just got an email this weekend about recent hucksters selling these in Australia, it’s a woo that just won’t die, possibly because it’s very attractive to cranks.

    The story behind the Rife machine has all the perfect components of crankery. You’ve got the miracle cure for cancer, suppressed by the mainstream medical profession, with a visionary hero (Royal Rife) who like Galileo was persecuted for defying the orthodoxy and whose revolutionary inventions were destroyed to prevent him from being validated.

    So what quack sites did I have to go to to learn about this absurdity? What den of psuedoscientific iniquity is pushing this story off as fact? Why Wikipedia of course.
