A cigarette for the beginner is a symbolic act. I am no longer my mother’s child,

I’m tough, I am an adventurer, I’m not

square...

...as the force of the psychological symbolism

subsides, the pharmacological effects take over to sustain the

habit

But others forces are at work...

MINDSPACE

MINDSPACE

Messenger: We are influenced by who communicates information

Incentives: Our responses are shaped by biases and shortcuts

Norms: We tend to do what those around us are already doing

Defaults: We ‘go with the flow’ of pre-set options

MINDSPACE

Salience: Our attention is drawn to what is novel and seems relevant to us

Priming: Our acts are often influenced by sub-conscious cues

Affect: Emotional associations can powerfully shape our actions

Commitment: We seek to be consistent with our public promises, and reciprocate acts

Ego: We act in ways that make us feel better about ourselves

The Science of Persuasion

6 weapons of influence

1.Reciprocation: You did something for me and now I owe you

2.Consistency: One thing I do or think leads to another

3.Social proof: 9 out of 10 cats prefer...

4.Liking: I will buy Tupperware from you because I like you

5.Authority: More doctors smoke Lucky Strike

6.Scarcity: Get it now, or I’ll be sorry when it’s gone

Robert Cialdini, The science of persuasion, Scientific American, 284, 76-81.

Some “biases” in real behaviour

• Loss aversion

• Recency

• Peak experience

• Herding

• Heuristics

• Omission

• Habit

• Confirmation

• Hyperbolic discounting

3. Understand the population

Use segmentation

Able to act

5: Cautious participants I do a couple of things to help the environment. I’d really like to do more, well as long as I saw others were. 14%

2: Waste watchers‘Waste not, want not’ that’s important, you should live life thinking about what you are doing and using. 12%

1: Positive greensI think it’s important that I do as much as I can to limit my impact on the environment. 18%

3: Concerned consumersI think I do more than a lot of people. Still, going away is important, I’d find that hard to give up..well I wouldn’t, so carbon off-setting would make me feel better. 14%

4: Sideline supportersI think climate change is a big problem for us. I know I don’t think much about how much water or electricity I use, and I forget to turn things off..I’d like to do a bit more. 14%

7: Honestly disengagedMaybe there’ll be an environmental disaster, maybe not. Makes no difference to me, I’m just living life the way I want to. 18%

6: Stalled startersI don’t know much about climate change. I can’t afford a car so I use public transport.. I’d like a car though. 10%

Willing to act

4. Be careful with the relationship between citizen and state

4: Establish the case for intervention

“The only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant”.

But… Children? Addiction? Influence of background? Mental illness? Collective costs? Regret...?
