We cannot change, or improve, residents’ decisions unless we know their decision mindware (how, and
why they decide, or not)

Human “decision mind-ware” is made of 2 systems
designed to see the waitress smiling, first.
SYSTEM 1FAST!AutomaticEffortlessAvoids too much thinking Loss averseConfused by infoForgets own values, long term goalsBiased
SYSTEM 2… slow… deliberate.. Reads all information… balancing losses and gains)…remembers deep, long term goalsAware of biases

What’s the difference between
nudging behaviour vs decision?
“Behaviour”
- normally a binary action (“I recycle or not”)
- well-known but not appealing (e.g. I know recycling means using a recycling sack or bank, but my habit is not to recycle).
- Nudging behaviour is about breaking habits, or creating new.
“Decision” (choice)
- many possible options (often more than 2 (“I choose a payment method to pay for rent arrears”)
- some options are new and need to be discovered by new information
- Nudging decisions is also about creating informed decision-making and educating ‘conversations’ (I chose X because...)

Most decision helpers are optimistic

But we offer choice

Citizens choose by System 1

What do you think residents care
most about when choosing a
hospital online?
Case: Helping to choose a high-quality hospital for elective surgery

365!
We are not
overloaded by
choice, have the
time and
resources to
compare all 365
hospitals
We can understand numbers,
invert scales, combine conflicting
information, map indicators to our
preferences, scroll down…
We are not afraid
or stressed by the
statistics

Which Choice Architecture could…
(Government) (King’s Fund)
Decrease Effort for online user
(NHS choices team)
Improve transparency, informed choice
(taking into accountdifft age, numeracy etc)
Increase # residents choosing
Best Quality Hospital

The 3 stage project (for your later reference)
Focus GroupsPhase 15 choice
architectures
Phase 22 architectures
- simpler and more consistent format of data;
- clearer and more consistent definitions of indicators;
- more balanced scorecard
Effect of designs on:
a) Choice outcomes (Prop People choosing best)
b) Awareness of informationc) Post-choice perceptionsd) Information search (heatmaps)
Any long-lasting effect of Phase 1 on subsequent choice and choice perceptions?

Before nudging a decision, structure it!
Create “Choice Menus”:
- 2-5 Options (e.g. hospitals)
- 2-3 Clusters of Criteria
- First the most important that is forgotten
- Last the one that people overweigh/think most about
- - Easy labels+checks + numbers13

Design Choice (Not information) Architectures for System 1
Test them before choosing the one to implement (here, just 4)

1. Best first, Sort by Quality
Best Quality is FirstActive Choice Required

2. Opt-out Default(Highlight the best overall on all the criteria and set as opt-out default)
Same Scorecard as Sort-by-Quality
Best is highlighted pre-selected

Best is 4th (away from edge and close to
middle). Active choice required
Scorecard Pre-sorted by Distance
(Quality not Mentioned)
3. Sort by distance, best in the ‘hotspot’

4. Preference Articulation (list all objectives that are relevant and ask to rank them by own preferences)
ac
18
Rank all indicators from 1 (most important) to 9 (least important to you)
The first indicator tells you how good the quality is… Numbers greater than 100 mean…
…No Hospital is excellent across all indicators…You will need to make trade-offs…
Then Scorecard(same as Best-in-Hotspot)

When did most residents choose the highest quality hospital?
Best First?
Opt Out Default?
Hotspot?
Preference Articulation?

1. Present your residents a simple menu/scorecard laying out 2-5 options available?
2. Highlight the option recommended?
3. Include the do-nothing/no-decide option (as choosing not to choose is a choice!)?
4. Include a checklist of objectives?
5. Ask to interact and rate these objectives by importance?
Going back to your decision, can you…
