Week 11 - Nudging Flashcards
What is a Nudge?
Any aspect of the choice architecture that alters peoples behaviour in a predictable way without forbidding any options or significantly changing economic incentives
What MUST a nudge be?
Easy and cheap to avoid
What MUSTN’T a nudge be?
A rule or mandate
eg making healthy food to notice = nudge
banning junk food DOES NOT equal a nudge
Nudges use what?
Choice architecture
How are the 2 ways nudges work?
By improving people’s use of heuristics through the aspect of choice architecture
What are the 2 systems for processing information?
Systematic: Slow, thought out, deliberate
Heuristic: Fast, automatic, short-cut
What is Choice Architecture?
How the choice is organised
What context it is presented in
eg coffee situation
What does Mapping of Choices mean?
How well can people make choices that are in their best interests?
- Do people understand their options
How to promote good mapping of choices?
Present info and choices clearly
Provide feedback
Provide useful default options
What does it mean to give feedback?
Info about good or bad outcomes for choices
eg speed limit signs
What is the status quo bias?
Leaving things as they are (we must have a good reason divert from the status quo)
What is the Availability heuristic?
Using info that is readily available
What does it mean when nudges can work by establishing social norms?
EG what SHOULD i do in this situation
- reusing the towel situation
What is Centrality Bias/Edge-Aversion?
People often avoid the edges when choosing from arrays
Why do people engage in centrality bias/edge aversion
Due to probabilistic mental models (cues in order to take the best option)
