Thaler & Sunstein
Types of nudges
Hansen & Jesperson
Types of nudges
4 categories:
- unconscious vs conscious
transparent vs non-transparent
System 1 Nudge
–> perceived as more autonomy threatening
System 2 Nudge
–> perceived as more effective for making good decisions and more necessary for behaviour change
Type 1 Nudge (Hansen & Jesperson)
aimed at influencing behaviour maintained by automatic thinking or consequences therefore without involving reflective thinking
Type 2 Nudge (Hansen & Jesperson)
Transparent nudge
individuals understand expected behavioural change & means by which it likely to occur
Transparent Type 1 Nudge
reflective thinking is not engaged in what causes the behaviour change in question
–> reflective thinking is by-product
e.g. playing relaxing music while passengers board plane to calm them down
Transparent Type 2 Nudge
engages in reflective system in a away that mens it easy for citizen to reconstruct intentions and means by which behaviour change is pursued
e.f. fly in urinal, prompted choice for organ-donation
Non-Transparent Nudge
Individuals less likely to recognise the possibility of behaviour change, and they cannot reconstruct the means by which changes could occur
Non-Transparent Type 1 Nudge
causes behaviour change without reflective system and in a way that doesn’t make it likely to be recognised and transparent
Non-Transparent Type 2 Nudge
reflective system has to be engaged but doesn’t happen in a way that by itself gives people epistemic accede to intentions and means by which influence is pursued
e. g.
- clever framing of risks aimed to influence one’s decision-making
- aimed at affecting decision-making by clever framing, compliance, anchoring
