3. Theoretical Background
- Current state may impact the
amount of food ordered
- Alternative theories
Hot-Cold Empathy
Gap
The impact that nudges
involving social norms may
have on reducing this gap
Social Norms &
Nudges
How PB201 and PB100 are both
explored
PB201 and PB100

4. Research Question
Can information on social norms regarding food consumption
neutralise the effect of the hot-cold empathy gap on ordering food?
The individual’s state of
being hungry or full will
affect the amount of food
they order for their dinner,
measured in calories;
hungry individuals will
order more food than full
individuals
Hypothesis 1
The addition of a social
norms intervention will
reduce the amount of food
ordered by hungry
individuals and increase
the amount of food
ordered by full individuals
Hypothesis 2

5. Experimental Flow
2 X 2 Between Subjects Design
Hungry (Before
lunch)
Full (after
lunch)
Intervention
Social Norms - -
None (Control) - -
“Most people buy X calories worth of food per hungry/full person.”

6. Data Analysis
-Demographic Information (e.g Age, gender, BMI)
-Descriptive Statistics (mean, skewness, standard
deviation)
-Two-way ANOVA

7. How analysis relates to hypothesis
If hungry individuals order significantly more food
than non-hungry individuals, there is evidence of
a hot-cold empathy gap in hungry individuals
Outcome 1
If in our results, food ordered by the hungry condition
is significantly closer to the non-hungry condition
then social norms is an effective way of neutralising
hot-cold empathy gaps in food orders
Outcome 2
Average
