Liar, liar: Why deception is our way of life
By Dorothy Rowe, New Scientist
How did we get ourselves into this mess? Continual wars and conflicts, climate change and economic crisis loom at the international level, while as individuals we continue, generation after generation, to inflict pain and suffering not only on other people but on ourselves. Why do we have such difficulty in learning what we most need to know to mitigate our most destructive behaviours?
Throughout history there have been a few individuals whose insight into what goes on inside us is as clear as their understanding of what goes on around them, yet with what looks like self-induced stupidity most of us have been wholly unable to learn what they have been telling us.
Take the Stoic Greek philosopher Epictetus. He commented on human behaviour this way: "It is not things in themselves that trouble us, but our opinions of things." In other words, it is not what happens to us that determines our behaviour but how we interpret what happens to us. Thus, when facing a disaster, one person might interpret it as a challenge to be mastered, another as a certain defeat, while a third might see it as the punishment he or she deserves. Crucially, the decisions about what to do follow from the interpretation each person has made.

Can Dopamine Make Your Future Look Brighter?

Our choices are dramatically influenced by the chemicals circulating through our bodies – so how much free choice do we really have? Is free will just an illusion? - Ilene
Can Dopamine Make Your Future Look Brighter?
By John Cloud, courtesy of TIME
Humans have expended a great deal of intellectual energy over the past few thousand years trying to understand the morality (or amorality) of seeking pleasure. Most of philosophy begins with the question of what defines the (or a) good life. But what if the answer to what makes us happy comes down to how much of a particular chemical is circulating in our brain at any particular moment?
(As with risk taking, romantic love, religousness…. – Ilene)
The neurotransmitter dopamine isn’t quite that powerful, but evidence has been mounting for the past 40 years that its activity is key to helping the brain recognize experiences that cause pleasure. The more dopamine a certain event (having sex or eating ice cream, say) triggers, the more strongly that event gets hard-wired in the brain, and the more intensely your brain drives you to revisit it.
That knowledge also helps the brain figure out how much pleasure it can expect from future experiences and, therefore, influences virtually any decision you make about what you might like or not like: whether you should buy the red shirt or black one, whether you’ll enjoy watching Top Chef over Mad Men, whether you should leave your job or whether you should move in with your boyfriend.
Now a new paper in the journal Current Biology shows for the first time that by tinkering with levels of dopamine in the brain, researchers were be able to influence people’s future decisions in a reliable, predictable way. Led by Tali Sharot and Tamara Shiner of the the Wellcome Trust Center for Neuroimaging at University College London, scientists presented 61 healthy volunteers with 80 different vacation locations, such as Brazil, Thailand and Greece, and asked the volunteers to rate how happy they thought they would be visiting each place. Later, 29 of the participants were given 100 mg of levodopa (or L-DOPA), a drug that increases dopamine in the brain; the other 32 were unwittingly given a sugar pill. Forty minutes later, each participant was given a questionnaire about their emotional state, then a list…

What’s the Shape of Your Recession?

What’s the Shape of Your Recession?

Clueless Commentators
Over the past few years we’ve had endless economic experts opining on the nature of the recession. From initial hopes of a bouncy V shaped recovery we moved onto a sluggish U and then a very droopy looking L before a dose of government pump-primed financial Viagra re-erected the idea of the V. More pessimistic predictors – mainly those who originally plumped for a U or an L – are now hopefully suggesting that we’ll get a double-dip W or a triple-dip VW in an attempt to save their remaining credibility.
Of course, the reality is that none of them have the faintest clue because none them possibly can have the faintest clue. We are, as always, in the uncharted waters of the future. The only letter that needs apply is the X that marks the spot where we bury the commentators and their useless predictions.
Blithe Ignorance
As we’ve sailed on through the treacherous shoals of economic uncertainty people have naturally looked to the world’s experts for advice. Occasional suggestions by central bankers, who actually have the real data to analyse, that they don’t have a clue what’s going to happen have resulted in shudders across world markets. Meanwhile commentators have happily carried on making essentially random predictions based on their thirty years or so experience of largely benign economic times. It’s like watching a weather forecaster from Hawaii trying to make predictions for the Mid-West: amusing, but not terribly helpful.
In fact, as economies have uncertainly recovered we’ve seen the standard reactions by experts who’ve been caught out (see You Can’t Trust The Experts With Your Investments). Many have simply ignored the fact that they were wrong and have blithely continued to make further predictions; presumably on the grounds that yesterday’s media makes tomorrow’s lining for kitty litter trays. Others have opted for the standard “I was right, but not yet” or “I was wrong, but for the right reason” responses as though getting your timing wrong about the world economy and causing people to flee into overpriced government bonds just as the biggest stockmarket rally in history kicked off is a normal sized mistake.
