1 The context of my research
Before inquiring into the notions of explanatory value and
understanding, let me briefly provide my research context: Overarching
the process is a theory of intergroup contact (Allport 1954; Brown and
Hewstone 2005; Pettigrew and Tropp 2006). The theory and the field of
research that stems from it study how contact: a meeting between members
of conflicting social groups, could reduce prejudice and improve
attitudes. My research, focusing on the Israeli-Palestinian conflict,
explores technological and creative means for such a contact. First, I
am using telerobotics as a medium – enabling a physical encounter
between the groups without the logistic effort of bringing individuals
to the same space (A. Peled, Leinonen, and Hasler 2020). Second, I use
puppet theater as a collaborative and creative tool for expressing and
dealing with social and political concerns (Avner Peled, Leinonen, and
Hasler 2024a). Therefore, we could define the research as
interdisciplinary – combining social sciences, human-computer
interaction, and the arts.
2 Scientific research as Active Inference.
The capacity of science to explain reality is laden with logical and
metaphysical challenges (Godfrey-Smith 2003), even more so in the social
sciences (Risjord 2022). I propose an alternative view of scientific
research that is more action-oriented than explanatory. We start by
declaring the goal of scientific research not to provide a water-tight
explanation of phenomena but to construct a model of the world that
advances the survival of society. Explanation and understanding are thus
tools by which the model is enriched. Additionally, insofar as the goal
of societal survival is entangled with the survival of the earth and its
ecosystem (Barad 2007), the model is not human-centered.
I propose a model based on “Active Inference” (Parr, Pezzulo, and
Friston 2022). At its core, Active Inference is a framework for
cognitive sciences and computation, but the theory and its underlying
principle – The Free Energy Principle (FEP), have been explored as
models for scientific research (Pietarinen and Beni 2021; Balzan 2021).
FEP is an optimization approach for Bayesian inference – a popular
statistical method for casual modeling (Risjord 2022). In Bayesian
inference, empirical evidence is repeatedly assessed against an existing
“prior belief model” (consisting of probabilities of events to occur
given various parameters) and updated with the new evidence, forming a
“posterior belief model”. The trouble with Bayesian inference is that
assessing the fitness of a model to the evidence (its correspondence
with reality) is infinitely complex when the model includes infinite
parameters. This problem is referred to in the literature as the problem
of “marginal likelihood” (Chan and Eisenstat 2015). It is somewhat
analogous to the impossibility of providing a “thick description”
(Geertz 2008) that describes all possible factors or interventionist
counterfactuals (Woodward 2005) for all possible parameters.
Instead of attempting to devise complete analytical models of the world,
Active Inference chooses actions that minimize “Free Energy” (Friston et
al. 2023). Defined as complexity minus accuracy, the goal is to
reduce the complexity of the model while increasing its accuracy. This
is also described as minimizing “surprise” or “prediction errors”.
Additionally, by evaluating “Expected Free Energy” (Millidge, Tschantz,
and Buckley 2021), the decision-making algorithm in Active Inference
chooses (in a balanced manner) actions that it expects would lead to
gaining new information, increasing overall prediction accuracy and
widen the spread of information. Karl Friston, the inventor of FEP,
suggests that it is not just an arbitrary optimization method but a
principle inherent to all living systems. A well-defined system (what
Friston calls a “Markov blanket”) necessarily adapts to its surroundings
to maintain its boundary and not dissipate into the environment; It does
so by minimizing the prediction error of its actions (Kirchhoff et al.
2018). I suggest applying FEP to scientific research. The Markov
blanket, in this case, is society as a whole, maintaining its survival
by conducting science. Scientific research under Active Inference is not
obligated to explain certain phenomena as long as it works toward
minimizing the Free Energy of society [^1].
3 The state of intergroup conflict research
From the perspective of FEP, research that strives for a decrease in
violence and conflict in society is productive. A system occupied with
internal conflict and self-deprecation is not spending its energy on
harmony and adaptation with the surroundings (as an anecdote, the
discourse on climate change in Israel and Palestine is scarce (Roberts
2020)). Mass violence and war amount to an unproportioned decrease in
diversity, robustness, and productivity – reducing the overall
sustainability of society. Research in intergroup contact theory
attempts to construct a model that reduces conflict. Typically, social
science models are repeatedly contended, contradicted, and nuanced. That
does not mean that research is without value. Every paper in contact
research is another piece of a puzzle that increases the accuracy of
some predictions and illuminates various concepts in conflict
resolution, thereby reducing the complexity of the task at hand.
Nevertheless, in the current battle between the forces that drive group
polarization (such as social media echo chambers driven by the human
tendency to confirm existing beliefs (Knobloch-Westerwick, Mothes, and
Polavin 2020)) and the forces that drive reconciliation (such as
intergroup contact), it is apparent that the former forces are more
potent. From a computational perspective, we could say intergroup
contact research is at a local minimum. The research is making
incremental progress but in too small steps compared to the negative
direction in which society is heading. At this point, we need research
that favors exploration on exploitation – research that, although
slightly increases the complexity of the model, provides more pathways
for action, discovering escape routes from existing paradigms.
4 A scientific trickster
As pointed out, my research began as an intersection of two disciplines.
In the initial theoretical and survey work Avner Peled, Leinonen, and
Hasler (2024b), we applied Human-Robot Interaction (HRI) theories to
intergroup contact and vice-versa. We explained survey results by
merging the two fields and later tested the resulting hypotheses in
co-design workshops (Avner Peled, Leinonen, and Hasler 2024b). This kind
of work amounts to an expansion of the field of action – an increase of
model entropy toward the mitigation of conflict, along with a steady
increase in the predictability of actions taken in this path. However,
as I move closer to the end of the doctoral program, I embrace the
position of standing at the crossing of two pathways as a strategic
choice. In my latest telerobotic workshops with Israeli and Palestinian
participants (Avner Peled, Leinonen, and Hasler 2024a), we used methods
from the Theatre of the Oppressed by Augusto Boal (2008): a framework
for involving non-actors in political theater. Boal introduces the role
of the “Joker” – a workshop facilitator and trickster of sorts
(Schutzman 2018). The Joker bends the rules, sketches out boundaries,
crosses them, mediates, dissolves, and playfully and humorously tackles
sensitive topics – All to enable meaningful social discourse through
theater.
I see myself as a scientific trickster, alluding to the mythological
role of tricksters as mischievous yet beneficial mediators (Hyde 1997).
I am situated at the border of Art and Science, meditating and
cherry-picking models from one to another and questioning the
definitions of both. In our participatory workshops, we attempt to blur
the lines between HRI researcher and user, theatre actor and spectator,
and challenge the idea of national borders (with telerobotics).
Importantly, we opened a “corridor of humor” – a concept articulated by
trickster artist Marcel Duchamp (Weppler 2018). We used humor as a tool
for nonlinear thinking, as the participants produced robotic puppet
shows about the conflict. So, to answer the question: “How does my
research promote understanding?”: In some cases, it is a linear
expansion and progression of the societal model, unifying different
theories in a single architecture. But above all, it is the meta-level
understanding that science can be art, that art can be science, and that
humor and play can be research. The analytical value is secondary to
promoting the robustness and flexibility of the Free Energy model toward
the survival of society on this planet.
