Lots of psychology isn’t rocket science – it’s not exactly stuff you couldn’t have figured out yourself if you’d have thought about it for long enough. Often the conclusions from some area of investigation are explained to you and you think ‘Well, hey, that’s obvious’. And of course there’s an argument that true answers often should be obvious, once you’ve been told them.
One of the the things I hoped we could do with Mind Hacks was give people framworks for looking at how our minds work, and how we interact with the environment, so that it becomes easier to spot the obvious in advance. After all, we all have minds, so we all have access to the raw data to draw the conclusions – it’s just that there are many things you don’t notice until you’ve learnt to see them. (Until someone stops me i’m going to call this ‘cultivated perception’).
So, I should be working on designed a questionnaire (a sign that I committed grevious sins in a past life?) and I noticed how I could improve it with a little lesson from Chapter 8 of the book.

All animals yawn (see animalyawns.com) and in humans yawning seems to be contagious. Seeing another person yawn, or even just reading about yawning can make you yawn. (We talk about unconscious immitation in chapter 10 of the book). James Anderson from the University of Stirling gave a lecture in Sheffield last week about yawning – in the introduction he told us that when he lectures on yawning lots of people in the audience, well, yawn. But his talk was only yawn-inducing in the social-contaigon sense.
Yawning, it seems to me, may provide us with paradigm case of an automatic behaviour that, moving along the phylogenetic scale, has become co-opted into a quasi-voluntary social signal.

This is a hack which never made it into the book, but we thought it worth sharing. At this point, to get the most out of this hack, look at this figure (in a pop-up window) quickly before reading on. It’s not important to try and work out what it is, but have a good look. Seen it? Now, without further ado…
Hack #102: Alter Input With Expectation
The balance between feed-forward and feed-back connections in the brain gives a clue to the balance between raw sensation and expectations in constructing experience.
Feedback is ubiquitous in the brain. The brain is not just massively parallel [Hack #52], it is also massively interconnected- an awesomely complex cybernetic system.

Our heroic contributor Alex Fradera has a nice way with some kind words about the book here
Suffice to say that if you want to know about the brain, and the mind, and you want a bunch of mavericks to illuminate it using cognitive and visual illusions, pop culture and web-references, wrapped up in a very chic, sleek simple design, you couldn‚Äôt go far wrong
Need To Know give us a mention too (cheers guys) and we got our first review at amazon.com which was four stars and said, amongst other things that the book is ‘unconventional in several ways’ – which i like!
Sometimes it isn’t how much sleep you got that’s important, but how much sleep you think you got.
Our own perception of how much we slept during a night can be startlingly inaccurate. Dr Allison Harvey (now of UC Berkley) took insomniacs and measured how much they actually slept during the night. Despite the insomniacs reporting that they had only slept for two or three hours, they had in fact been asleep for an average of 7 hours – only 35 minutes less than a control group who didn’t have any problems sleeping.

There was a great Analysis programme on radio 4 last night: The Economy on the Couch which was about behavioural economics, neuroeconomics (whatever that is) and ways in which we fail to act like the rational agents that standard economic theory supposes us to be
One irrationality- a human frailty for fairness- is revealed by a thing called the Ultimatum Game. The Ultimatum Game works like this. I am offered some money, say ¬£100, on the condition that I share it with you. I get to decide the split, and you get to say if you accept it or not. If you accept, we get the money in the proportions I determined, if you reject my split then neither of us gets anything. So what would you do if I offered ¬£1 to you, leaving me with the other ninety-nine?

Hello. And I’m Tom Stafford, the other author of the book. While I was doing my degree and PhD I kept notes on lots of funny little things in psychology and neuroscience, although I never really knew why I was doing it. Then along came Matt and the idea for the book, and I had a place for many of the things I’d jackdawed over the years. But they were just enough to get us going. The rest of Mind Hacks me and Matt discovered during our Summer of Book – and that was a hell of a ride I can tell you. All summer we kept finding out new exciting things, and we knew that we’d only have time or space for a fraction in the book. Hopefully some of them will end up on this weblog, along with other things out there that we missed. There’s also room for all the discussions we didn’t have in the book, about all the wider issues raised by this stuff, and especially about different implementations of the hacks we suggested. I’m looking forward to finding out some more cool things and having some cool conversations on mindhacks.com…I hope you’ll join us.
