Climate Change Bad Science
Ben Goldacre defends Climate Science against the rudeness of sceptics: Copenhagen climate change blah blah – Bad Science
Leaving aside his other arguments, which you can be rude about if you want to be, he repeats this argument:
We’re predisposed to undervalue adverse outcomes which are a long way off in the future, especially if we might be old or dead soon.
Granted we all "undervalue" long term adverse outcomes or apply questionable discount factors, which might be a more neutral way of putting it.
But is there any evidence that old people discount these more than young people?
It is young people who believe they are immortal and drive fast and party hard as they fritter away their money. Old people look both ways, join the RSPB and tinker with their wills as they worry over their grandchildren.
Arguing that old people don't care about climate change because they don't care about the future may be based on facts, but I have never seen a source. It maybe that old people are sceptical because they "have seen it all before". Without a basis for the assertion it is worthless and isn't worthy of his column.
