6. How can we improve
our policies to
induce behavioural
change?
7. Policies improve by using socio-cognitive
theories
Organ DonorsDonorPercentage
8. Policies based on socio-cognitive theories on
human-decision making
To what extent can we
improve our understanding
of social phenomena
through agent-based
simulation by endowing
agents with social
practices?
Does this understanding lead to better policies?

Computationally valid
20. How do we set-up the experiment?
Gather experts on
human-decision making
sociology
Show a transcript of
how an agent made
the decision
Give short introduction to
our definition of social practices
Facilitate discussion about
the accuracy of the depiction
and possible extensions of the
model
