Increasing relevance of behavioural economics
Behavioural Economics, Nudge, and Libertarian Paternalism
have arrived in Ireland.
Focus is on boundedly rational decision making.
In particular: Self-control problems.

Self-discipline: “The capacity to begin tasks
and follow through to completion despite
boredom or distractions” (NEO-PI-R)
The capacity to voluntarily regulate thoughts,
feelings, and behaviour in the service of a
valued long-term goal
Important when confronted with health-
harming short-term rewards and temptations
Important in initiating goal pursuit and forming
healthy habits
What is self-control? Why is it important?

We seek to investigate in the population:
Childhood self-control → Adult behaviours
Intricacies of how self-control operates
in everyday life
Does self-control explain problematic behaviours?

4. Shows perseverance.
5. Easily distracted.
6. Pays attention in class.

Childhood self-control → Health outcomes
Predicts midlife (age 42 BCS, age 45-55 NCDS):
• Self-rated health
• Pain
• Psychological distress
• Chronic conditions
• Whether conditions are limiting
• Physiological dysregulation (NCDS)
• Death
Association is similar to socioeconomic status on average

and health outcomes?

Why? What is the mechanism in daily life? How do the lives of
people with high (versus low) self-control differ?
We wanted to look in detail into people’s daily self-control
experiences.
But that is not easy…
Self-control is important for life outcomes

Phase 1: Systematic reconstruction of “episodes” on the
previous day in a short diary.
“Think about what you did and how you felt yesterday
around 1pm. Think of this as an episode in a film…”
Phase 2: Follow-up questions for each episode about time,
location, activities, social interactions, emotions, desires, self-
control …
“How did you feel? Was there anything that you
wanted? …”

People with high trait self-control:
• Are NOT better at resisting temptation (59.8% vs 60.5%).
• Are NOT more likely to try to resist (59.8% vs 60.5%).

→ More research is needed on the determinants of desire and
temptation. The DRM can help.
See also Fujita (2011), Hofmann et al. (2012), Ent et al. (2015), Milyavskaya & Inzlicht (2018).
Traditional definition:
The capacity to voluntarily regulate
thoughts, feelings, and behaviour in
the service of a valued long-term goal.
Traditionally overlooked aspect:
The ability to pro-actively structure
one’s life to encounter fewer
problematic desires. Avoiding rather
than resisting temptation.

Discussion of DRM research
Summary: The DRM provides information about the where,
when, with whom, etc. of well-being and self-control across
many domains.
Limitations: Self-reported, recalled, correlational.
Relevance: Potential to design and test business & policy
interventions.
… For example using domain-specific DRMs in areas
such as medication, work-arrangements, teaching,
commuting, food consumption, entertainment,
sleep quality, social media use, etc…

1. Do sensory cues trigger food desires?
2. Do people use resistance strategies?
Abbreviated online DRM focusing on food
• Did you want to eat something during this episode?
• Conflict, resistance attempt, enactment
• Did you see/smell/hear anything food related?
• Did you use any of these resistance strategies?
708 episodes and 380 food desires. N=254, Age = 37 (SD=13),
Female = 61%, BMI = 25.6 (SD=5.8).

1. Sensory cues trigger food desires
• But some cues lead to food desires more than others.
• Implications of DRM data for regulation and business.
2. People use resistance strategies and are less likely to eat
when they try to resist.
• But resistance strategies differ in effectiveness.
• Implications of DRM data for teaching self-control.

Lack of knowledge: We might want to live healthy/happy lives,
but we do not know exactly how
→ Information based interventions often require planning,
monitoring behaviour, inhibiting conflicting activities
→May be most beneficial to those with higher self-control
Self-control problems: We are distracted, fail to keep goals in
mind, and have difficulties resisting temptation
→Training, self-control strategies (breaking cue-response links),
or nudging and non-reflective processes (to reduce the
prevalence of cues or the desirability of unhealthy products)
Potential reasons for problematic health behaviours

Interventions (g = 0.32):
1. Follow rules
(e.g. what to do when… angry,
others teasing, do not want to play)
2. Self-instructional training
(e.g. using verbalisations as guide)
3. Video modelling of
appropriate/inappropriate behaviour
with follow-up observation of child

Early interventions
• Explaining why well-know early intervention programmes may be effective (e.g. PPP: Heckman et al., 2013; PPP/ABC: Conti et al., 2016)
• Tools of the Mind preschool programme which targets self-regulation (support: Barnett et al., 2008; Blair & Raver, 2014; Diamond et al., 2007; mixed evidence: Jacob & Parkinson, 2015)
• Structured teacher-delivered curriculum focused on “fostering patience in the classroom” effective over 3 years (Alan & Ertac, 2017)

What training?
Overriding dominant responses
(e.g. using non-dominant hand,
avoiding slang, computer tasks)
Muscle metaphor (stamina,
strength) repeated control predicts
generalised improvement in self-
control
33 studies and 158 effect sizes:
small-to-medium effect g = 0.30
Bias corrected: gcorrected = .13 to .2454

Self-control resistance strategies
![Page 56: Self-control: health outcomes, daily experiences, and policy … · 2019-03-16 · Self-control: health outcomes, daily experiences, and policy interventions Liam Delaney, UCD QUB](https://reader033.fdocuments.net/reader033/viewer/2022042204/5ea53deab45921555f1ea30d/html5/thumbnails/56.jpg)
Nudging and situational influences
For healthy behaviour:
Incentives (e.g. for changes in smoking, eating, alcohol consumption, physical activity: Mantzari et al., 2015 review)
Default rules (e.g. impact of default choice of portion/plate/package size on selection and consumption: Hollands et al., 2015 review)
Make it easy (e.g. healthier options are the default choice or most convenient based on proximity and product order: Cardario & Chandon, 2017 & Bucher et al., 2016 reviews)
Stopping unhealthy behaviour:
Remove or reduce the salience of cues (e.g. cigarette packages, product displays) that elicit relatively automatic purchasing habits (overview Best & Papies, 2017)

“Hard” policy instruments
Regulation (bans, mandates) and incentives (taxes)
Less self-controlled may
be most responsive to
changes to cues and the
immediate reward/cost of
key behaviours though
this is debated (e.g.
Stautz et al., 2018)

tobacco control measures. Addictive Behaviors Reports, 1, 89 - 96. 57

Conclusion
• Childhood self-control forecasts economic and health
outcomes across life
• Links are comparable to SES-health associations with similar
lifespan pathways (e.g. smoking, weight gain)
• Desire and self-control processes can be measured in daily life
• Voluntary self-governance may include avoiding temptation
• Trait self-control measures (e.g. Tangney et al., 2004)
embedded in large scale intervention studies could yield key
insights about who self-control training, resistance strategies,
nudges, and other policy instruments are impacting on and why
