Here’s another reason not to try and terrify people out of conspicuous consumption, aside from the basic flaws in the “eco angel” approach and recent evidence that moralising is putting people off ethical consumerism. Some interesting research by Swiss psychologists found that warnings about death has the ironic effect of making some smokers want to smoke even more! The reason? They derive a self-esteem boost from smoking; warnings about death sent these smokers to a trusty source of self esteem to overcome that downhearted feeling – death-bringing cigarettes! So next time you tell someone that buying too much crap might cause planetary collapse, it’s fairly likely that your nasty nagging well send them running for a standard Western self-esteem boost: shopping.
