And Slaters Go Plop

This week saw the launch of the new Sign On campaign. The essence of it is that world leaders are meeting in Copenhagen later this year and by signing up to Sign On we are letting John Key know that we want New Zealand to agree to set a target 40% reduction of emissions by 2020.

The reasons I support this campaign are threefold:

Firstly, the science behind the need for a 40% reduction is clear and strong; anything less is not going to be enough.

Secondly, I don’t have the willpower myself to achieve a 40% reduction and I believe this is one of the roles governments perform; to constrain some of our harmful and selfish urges and to reward behaviour that is mutually beneficial.

And, finally, I see great technological opportunities for our civilisation should we find the motivation to innovate. I’m confident we’ll come up with energy, transport, agriculture and production technologies far superior to what we have now. We just need the will to do so. As I heard someone say, the bronze age didn’t come about because stones became scarce; bronze was a better technology. I think that there is another age waiting for us beyond the oil-and-deforestation age.

I also like the fact that the campaign is saying nothing about how we ought to go about achieving a 40% reduction. That can wait. First we need the will to make a commitment and then we can act on the best advice from our scientists, politicians and economists to see how we will best achieve this target.

So, if you share my opinions on this, head on over to the Sign Up website and add your name to their list of participants. And perhaps let your local MP know where you stand on the issue too. Hopefully enough people will step forward to let our prime minister know that we taking this seriously.

I’ve just finished reading Peter Singer’s new book, The life you can save – Acting now to end world poverty. In it he presents his arguments for why we ought to be acting to help those below the poverty line, discusses the obstacles and suggests methods for making sure that the money you give is effective.

Singer is a philosopher and an ethicist and, as such, presents a robust case for the need for charity as well as the wrongness of withholding aid when it is within our means.

He sets the scene with a scenario where you are passing by a pond and notice a toddler drowning in it. Most of us would be prepared to ruin our new shoes and clothing as well as make ourselves late for work in order to save the toddler. This would indicate that we actually value the life of this child over the cost of our clothing and over the interruption to our everyday lives.

But why don’t we act with the same urgency when we know for a fact that for a similar cost and/or inconvenience we would be able to save the life of a real child in, say, Africa?

Here Singer addresses many of the psychological issues that surround immediacy, perceived unfairness when others don’t give, balancing our legitimate selfish urges, being more vocal about our charity to create a better culture of giving and much more.

Having established that if we are able to help and we have no good reasons not to he then goes on to examine how to invest your aid wisely and ensure that your money is being used for what you intended. (I’ve often chosen my charities based largely on how little is wasted on administration – he deals with this and shows that it is more complicated than that).

The last part of the book is dedicated to establishing how much it is reasonable to expect us to give without turning us all off. Singer holds himself to his own standards and admits that even he can’t live up to them (he doesn’t mention it in the book but according to a radio interview I listened to he gives around 30% of his income). Think of it; if you can afford to buy a coffee when you could have had tap water then you have diverted potential aid from those who clearly need it more than you. Instead, he suggests a more realistic scale of percentages which, for most reading this, would be between 1-5% of our incomes before tax.

And all is not lost as he points out: in 1981 there were 1.9 billion people below the poverty line whereas today there are only 1.4 billion. Those numbers may seem close but consider that the fact that the world population has increased in the time and what this amounts to is that we have almost halved the percentage of people living below the poverty line in 30 years. Ending world poverty is achievable.

I thoroughly recommend you read this book.

No one believes that they are dogmatic. We’re all far too reasonable for that carry on. But we can all point to a number of other people who we would term as dogmatic and, with a little imagination, we should be able to understand that they probably don’t think they are dogmatic. This leaves us with a dilemma; how do we know that we are not being dogmatic ourselves? If we can see others acting dogmatically who are unaware of it then, chances are, we could be too.

By ‘dogmatic’ I am describing an absolutist kind of belief that, if I could summarise in my own words, boils down to the fact that you would really rather hold to what you believe than accept an alternative even if the alternative is true. Dogma is the belief you refuse to interrogate.

Dogmatism can get in the way of new truths. The reason for this is that if you are unwilling to honestly put a belief to the test then you will never find out if that belief happens to be false. A valid argument can be made that perhaps there are some beliefs that we’d be better off clinging to rather than risking finding out a truth that would cause you great unhappiness. Would you like to find out that your partner cheated on you all those years ago? What if we discover that we are really just a brain in a jar somewhere living a simulation? What if God really is imaginary? What if God really is real? Whether we dare to search for the truth of a particular matter is a personal decision. But if we refuse to honestly put our beliefs to the test then we ought to show a little more humility when telling others what we ‘know‘ to be true.

So, assuming we do want truth, how do we avoid dogmatism? The best way I can think of is to actually value truth over any existing belief. This can be excruciating, especially when a belief is foundational to any meaning you get out of life. I found it very difficult many years ago to say to myself in all honesty that I would hold truth higher than my belief in the existence of God. If you’ve never believed in God you’ll probably struggle to understand the significance of this but, to a believer, God is truth and so it can seem a kind of fundamental blasphemy to say that you would even challenge the idea. If you do believe in God, fear not, many respectable people have done what I did and kept their belief afterwards and I greatly respect them for it.

Other than valuing truth over existing beliefs I’ve come across another technique that can help to break the emotional attachment we often develop with our dearly-held beliefs. That is to regularly switch perspectives or, “state the opposite”. An example of this is to first say what you believe i.e. “Labour has the best health policies” and then say the opposite i.e. “National has the best health policies” or, “Act has the best health policies” and try to mean it. You can do this with just about any belief in which you are tempted to take sides and it really can help to make you more objective because it can lessen the effects of the ‘in-group/out-group’ factor.

Does anyone have any other good tips or tricks for finding truth that can be used by anyone regardless of their starting assumptions?

Less than a week ago, Act leader Rodney Hide sent an “open letter” to John Key outlining his stance on the Emissions Trading Scheme. In it he says:

So I’m not as worried about the future of the planet as I used to be. Even the UN now admits the globe stopped warming in 1998. [emphasis mine]

Take a look at the graph above and see what he’s done here. Technically 1998 was a very warm year and we’ve not had temperatures to match it since. Up until now people who have had an axe to grind have been misleading the public by phrasing this in ways to make it appear as if global warming has miraculously stopped somehow but Hide goes a step further and turns misdirection into an outright lie.

The UN have never, to my knowledge, said that global warming has stopped. The figures, even when taken selectively, don’t lend support to this concept.

Now, I like Hide as a person but we can’t afford to have people in his postition of influence spreading outright lies like this to the general public and for policy to be made based on these lies.

These are fairly old but I only just stumbled upon them. Some good insights from David Attenborough, Richard Dawkins, Richard Leakey and Jane Goodall on the environment and the future of our planet.

In 1973 the BBC released a TV documentary series in 13 episodes by mathematician Jacob Bronowski called The Ascent Of Man. 35 years later I purchased it as a DVD box set on the recommendation of a fellow science documentary aficionado.

It’s extremely good! And I’m not just saying that in the context of the era in which it was produced. Sure, some of the music grates on the nerves and some of the graphics don’t compare to what we are capable of these days but overall it’s got a depth that is often missing from the kind of documentaries found on the Discovery Channel. Actually, I take back my comment about the music; it features music from Meddle – my second-favourite Pink Floyd album – which, for me, redeems a multitude of musical sins.

Bronowski is thoughtful, poetic and very deliberate in every sentence. He gives you the feeling that he is treating you, the viewer, as an equal throughout and he conveys a sense of awe that is impossible to resist.

Most moving for me was a scene where Bronowski is visiting a Nazi concentration camp where many of his relatives were murdered. According to the interview with Attenborough in the bonus material the entire scene was spontaneous and filmed in a single take:

Bronowski died a year later of a heart attack at the age of 66.

I’m not sure whether this experiment has been done before but I was watching some videos on YouTube and noticed that with some speakers/shouters my heart rate seemed to increase. I’m not sure whether this is because I agree or disagree strongly with what they are saying or whether it is some kind of natural human response to emotion or a particular pitch in voices (sort of like the urge to cry when seeing someone else cry or laugh when you hear laughter).

An interesting experiment would be to play a series of audio clips of various speakers to people whilst monitoring their heart rates. It would be handy to have them also rate the clips on how strongly they agree or disagree with the speaker.

Once the results were in I then wonder if you could use software to analyse the audio and make predictions as to how strongly a person is likely to respond on an emotional level to a particular style of speech.

Recently Michael Shermer received an angry letter from a Jew who’d seen the film Expelled. He discussed the issue with Richard Dawkins and they decided to write an open letter in the hopes of setting the record straight for anyone else misled by Ben Stein and the deceptive film makers. Read on.

Dear Mr J

Michael Shermer forwarded me a letter from you which suggests that you have unfortunately been taken in by Ben Stein’s mendacious and/or ignorant suggestion that Darwin is somehow to blame for Hitler. I hope you will not mind if I write to you and try to undo this grievous error.

1. I deeply sympathize with you for the loss of your relatives in the Holocaust. Nevertheless, I don’t think that could really be said to justify the tone of your letter to Michael Shermer, who is a kind and decent man, as even you seemed to concede in your second letter to him, and the very antithesis of a Nazi sympathizer.

Now I truly understand who you atheists and darwinists really are! You people believe that it was okay for my great-grandparents to die in the Holocaust! How disgusting. Your past article about the Holocaust was just window dressing. We Jews will fight to keep people like you out of the United States!

Just look at those words of yours. Probably you regret them by now. I certainly hope so, but I’ll continue to write my letter to you, on the assumption that you still feel at least a part of what you wrote.

I’ve been bellyaching for years now about how silly it is that there is no way to cycle from Auckland’s North Shore to the city centre. I discovered getacross.org.nz yesterday and encourage everyone to take a moment to visit and register your support for the idea.

The bicycle is the most energy-efficient machine ever made. You give it a drop of oil each month and all you have to do is eat some food to power it. Bicycles take up far less room on the road and can travel almost half as fast as a car on the open road and it often faster than cars in city traffic. Cycling is also far better for your health than sitting in a car.

The next time you are able to observe a traffic queue at lights try to imagine all the cars gone and the occupants standing on the road exactly where they are. You’ll see that cars are a cumbersome and grossly inefficient way of getting around within a city.

The downside of riding a bicycle in a city built for cars is that you act like a human pollution filter (especially if you are puffing a bit) and it is horrendously easy to get yourself killed.

I’d like to see our cities redesigned to favour walkers and cyclists and have car traffic relegated to motorways and as second-rate citizens within cities themselves. Cars are still useful and are probably here to stay but we need to recognise that there are better ways of getting around our cities and that one of the things holding this back is the fact that our infrastructure is often designed exclusively for motor vehicles without regard to walkers or cyclists.
