Norms and Energy Use: Transportation in Groningen
Social Norm Theory (Cialdini, Kalgren & Reno, 1990) Injunctive norms: The behavior commonly (dis)approved. (Social) Sanction, Reward Descriptive norms: The behavior commonly displayed. Salience is important Aligned norms are stronger mm-dd-yy | 2
Project 1 • Promoting Orderly Bike Parking in Groningen
Previous Studies on Parking Problems • 44% Sees inappropriate parking as a problem • 67% Shopping • 64% Park < 30 minutes • 42% Not enough parking spaces
Making the injunctive norm salient Prohibition sign: 37% Prescriptive sign: 60%
Making the injunctive norm salient • How? • Please park your bicycle within the green area
PROPOSED FIELD EXPERIMENT • Method: • Pre and post intervention • Observational • Outcome measures: • % Bikers conforming to parking norm • % Bikers being socially sanctioned
Car Public Transit Negative Env Impact Bike Walk Behavior
Social Norms • Theoretical gaps: • Behavior suggestions: 1 vs. 2 alternatives • Norm effectiveness: perception vs. actual
Action Research • 4 conditions (all groups receive information + incentive) • Bike norm info • Public transport norm info • Bike + PT norm info • Control
Action Research • Procedure • Telephone Survey • Mail packages • Outcome measures • Telephone follow up survey • Objective assessment
The message (For people 5-10 km) • Many people believe that using sustainable transportation is the right thing to do. (injunctive) • 53% of people in your neighborhood use a bike or public transportation to go to work everyday. (descriptive) • Join us in making Groningen the most sustainable city in the Netherlands! • Please use a bike or public transportation when you go to work.
Expected outcomes • Practical • Decrease car use in city for segmented area • Theoretical hypotheses • Experimental groups will reduce car use more than control • Perception of norm may interact with reported norm
“ Well, I think the tram is a good plan, as long as it will go past Euroborg” “I used the tram in Rio de Janeiro, Brussels, Amsterdam, and a couple of other city's. I really like it”
Which message works best? • Injunctive: “The tram will be an appropriate means of transportation” • Descriptive: 60% of people traveling within Groningen will take the tram When both norms align tram preference will increase
Which message works best… and for whom? • Target group: People working in Groningen and living outside of Groningen • Important: Identify with the individual providing the testimonial Vs. Identification with models will increase tram preference
