Appearances Can Be Deceptive

I keep running into this demonstration of how strange our brains can be, so thought I’d have a go myself.

Have a look at the inverted face below.  Upside down, but still pretty cute eh?

Cute
Cute

Now look at the next picture where she’s turned the right way round – yuk!

But it’s exactly the same picture just inverted.  Our brains somehow pick out the individual elements of the face and reconstruct them as we normally expect to see them – I guess?   Personally, I can’t see a glum person in the top picture without turning my head to a degree – I’ve just discovered – not so good for my neck.

Not so cute.  Well, not so happy anyhow.
Not so cute. Well, not so happy anyhow.

This simple example was made by cutting, rotating, and pasting the mouth of the girl in the painting.

I saw something like this a couple of years back at the Exploratorium Science Centre in San Francisco.    The most recent demonstration I’ve seen was at the Weird Science event here in London earlier this month, where Richard Wiseman had us all in hysterics with a doctored picture of Margaret Thatcher.  That was doubly strange, as: (a) he’d turned the eyes round as well (which is the correct thing to do, but my painting struggles because of the hair) and, (b) rotated the image slowly, which revealed there is a certain point where the brain clicks over to seeing the ‘new’ image – the gestalt switch moment.

The Exploratorium exhibition also included so-called hybrid images of faces that change expression depending on how near or far you stand from them.  The effect still works very well on a computer screen, but you need to stand a long way back.

Not entirely sure how the brain processes compare for the two types of phenomena, but I find the ‘switch’ is more gradual with the hybrid images.   In deference to copyright I’ll not share the snaps I took, but you can find something very similar at the ‘Hybrid Images’ website owned by Dr.Aude Olivia, Dept. of Brain and Cognitive Sciences at MIT.

Dogs Are Spies From Venus

Contrary to popular belief, dogs are in fact spies from Venus.  So maintained University of London philosopher Steven Law at today’s Centre for Inquiry London ‘Weird Science’ event at Conway Hall.

In doing so, he applied the same faultless logic and interpretation of evidence used by young earth creationists, defending their belief that the universe is only 6000 years old.  Say no more.   And that was pretty much the tone for a day of  talks on the science of the weird, wacky, and flaky variety, from Ben Goldacre (”Bad Science” in the Guardian), Professors of anomolous psychology Richard Wiseman and Chris French, and philosopher Stephen Law.

Before sharing what a great show this was, let me digress for a bit on CFI London itself.   CFI London are at pains to explain in their FAQ that they don’t see science and reason as the be all and end all, but their positioning, and the topics they choose to discuss, for me at least force the issue of the incompatibility of science and religion.  Once you engage in a discussion on human psychology and the concept of what it means to be rational, the polite separation of science and religion becomes difficult to maintain.  It will be interesting to see how CFI’s event programme and various potential allegiances with secular interests develop.

Anyhow – it was a great show.  Richard Wiseman, hotfoot from an evening debunking mediums with his mate Derren Brown, illustrated how easily our perceptions can be fooled and our attention directed.   Familiar gestalt switch examples, like the rabbit-duck picture, made an appearance, along with excerpts from Richard’s various TV appearances, including a hilarious debunking of firewalkers, and these clips: the amazing floating cork, and the colour changing card trick.

You might remember Chris French, a psychology professor from Goldsmiths, as the guy who organised the dowsing trials on Richard Dawkins’ ‘Enemies of Reason’ TV show.  French re-lived with us that demonstration of the refractoriness of dowsers’ belief in the face of out and out debunking, and shared the results of a study that aligned personality traits with the likelihood of belief in conspiracy theories.  Those more prone to belief tend to (a) have low trust in people, (b) feel alienated from society, (c) are quick to make assumptions from partial evidence.

Writer, broadcaster, and medical doctor Ben Goldacre, while outspoken and opinionated, sticks to subject areas he knows something about.  That’s why he doesn’t address environmental issues and such like in his column and blog; their complexity not lending itself to case-based, winnable on evidence, 650 word analyses.

Ben shared his trademark disgust at alternative medicine and quackery, but majored on the rise and demise of medicine – through the Golden Age from the 30’s to the 70’s – after which the low hanging fruit dried up and major breakthroughs fizzled out.   His point – we should all get real that our level of understanding of much desease and suffering is still pretty minimal and (my words) – shit happens.   Although Ben’s book ‘Bad Science’ is still hot off the presses, his words reminded me of another honest text with a medical flavour – ‘The Rise and Fall of Modern Medicine’ by doctor and Telegraph columnist James Le Fanu; check it out.

Mainstream newspapers, and particularly their ‘humanities graduate’ editors (I’m sure he’s not talking about scientifically trained SciComs Grads here) got it in the neck big time, as did the various PR and press agencies that feed them.  Why, when literary criticism of the highest intellectual level gets column space, do we not see science coverage of the same professional calibre?  Goldacre also, admirably, subscribes to the BBC Horizon dumb down theory. (There are still Horizon dumb down deniers out there – believe it or not.)

Ben’s closing comments were encouraging  – but not for mainstream conventional print journalism.  He saw no solution to the dire journalistic picture he’d painted – it’s simply what the market wants.  But the rise of the blog is changing everything, cutting out a middle man who is adding less and less value.  And if we doubt a blog’s content? – check the source references; all good blogs provide the links.

What’s On

Early warning of three events into the new year that folk might like to consider joining. The Darwin related talks will sell out fast for sure – so think ahead – like me.

‘Weird Science’, Saturday 17th January 2009, London

Organised by the Centre for Inquiry, this all-day event promises to explore ‘Weird Science – science of the weird, and weird and flaky science’ . So pretty weird.

Expect presentations from Ben Goldacre, Richard Wiseman, Chris French and Steven Law. The venue is Conway Hall, Red Lion Square. Details at Centre for Inquiry.

Darwin Day Lecture, 12th February 2009, London

Prof Sir David King

You’ll be aware from previous posts that Darwin will be a bigger deal than usual next year, and appreciate the need to book early for events like the NSS lunch on 7th February. An event guaranteed to be even more popular is the BHA’s annual Darwin Day Lecture, given by Professor Sir David King on ‘Can British Science Rise to the New Challenges of the Twenty First Century?’ Good question. The event will be held at Conway Hall, Red Lion Square, London WC1 on Thursday 12th February at 6.30pm. Attendance at the lecture is £5 for members of the BHA and £7 for others. Tickets are available from the British Humanist Association on 020 7079 3580 or by email on info@humanism.org.uk

Dan Dennett Lecture, 19th March 2009, London

Dan Dennett

I’m not alone in tagging Dan Dennett as the more philosophical, patient, and possibly more persuasive member of the media-branded atheist quartet of Dawkins, Dennett, Hitchens and Harris.

On 19th March we will get to hear what will doubtless be an insightful and balanced analysis on ‘A Darwinian Perspective on Religions: Past, Present and Future’. Who better to deliver that than the author of Darwin’s Dangerous Idea: Evolution and the Meanings of Life (Penguin Science)
The location, prices, and contact details are as for the Darwin Day Lecture above.
