Section B
Climate change may be real, but it's still not easy being green How do we convince our inner caveman to be greener? We ask some outstanding social scientists.
[A] The road to climate hell is paved with our good ticians may tackle polluters whilescientists do battle with carbon the most pervasive problem is less obvious: ourown get distracted before we can turn down the break our promise notto fly after hearing about a neighbour's trip to mately, we can't be bothered to changeour unately for the planet, social science and behavioural economics may be able todo that for us.
[B] Despite mournful polar beats and charts showing carbon emissions soaring, most people find ithard to believe that global warming will affect them nt polls by the Pew ResearchCentre in Washington, DC, found that 75-80 per cent of participants regarded climate change as animportant respondents ranked it last on a list of priorities.
[C] This inconsistency largely stems from a feeling of powerlessness."When we can't actually removethe source of our fear, we tend to adapt psychologically by adopting a range of defencemechanisms," says Tom Crompton, change strategist for the environmental organisation WorldWide Fund for Nature.
[D] Part of the fault lies with our inner ution has programmed humans to pay mostattention to issues that will have an immediate impact."We worry most about now because if wedon't survive for the next minute, we're not going to be around in ten years' time," says ProfessorElke Weber of the Centre for Research on Environmental Decisions at Columbia University in the Thames were lapping around Big Ben, Londoners would face up to the problem ofemissions pretty in practice, our brain discounts the risks--and benefits--associatedwith issues that lie some way ahead.
[E] Matthew Rushworth, of the Department of Experimental Psychology at the University of Oxford,sees this in his lab every day."One of the ways in which all agents seem to make decisions is thatthey assign a lower weighting to outcomes that are going to be further away in the future," hesays."This is a very sensible way for an animal to make decisions in the wild and would have
been very helpful for humans for thousands of years."
[F] Not any the time we wake up to the threat posed by climate change, it could well betoo ff we're not going to make rational decisions about the future, others may have tohelp us to do so.
[G] Few political libraries are without a copy of Nudge: Improving Decisions About Health, Wealthand Happiness, by Richard Thaler and Cass argue that governments shouldpersuade us into making better decisions--such as saving more in our pension plans--by changingthe default essor Weber believes that environmental policy can make use of , for example, building codes included green construction guidelines, most developerswould be too lazy to challenge them.
[H] Defaults are certainly part of the social scientists are most concerned about craftingmessages that exploit our group mentality (,~, ~ )."We need to understand what motivatespeople, what it is that allows them to make change," says Professor Neil Adger, of the TyndallCentre for Climate Change Research in Norwich."It is actually about what their peers think ofthem, what their social norms are, what is seen as desirable in society." In other words, ourinner caveman is continually looking over his shoulder to see what the rest of the tribe are up to.
[ I ] The passive attitude we have to climate change as individuals can be altered by counting us in--and measuring us against--our peer group."Social norms are primitive and elemental," says rt Cialdini, author of Influence: The Psychology of Persuasion."Birds flock together, fishschool together, cattle herd perceiving norms is enough to cause people to adjusttheir behaviour in the direction of the crowd."
[J] These norms can take us beyond good dini conducted a study in San Diego inwhich coat hangers bearing messages about saving energy were hung on people's ofthe messages mentioned the environment, some financial savings, others social t was the ones that mentioned the actions of neighbours that drove down power use.
