        <p>In previous work we proposed a set of argument schemes for arguing about the putative intentions of foreign actors and for responses to their actions, and created an argument diagramming tool providing those schemes as cognitive building blocks.

      <title>Introduction</title>
      <p>
        Critical thinking about international politics often involves
reasoning about the beliefs, goals, appraisals, actions, and
plans of actors such as foreign governments. In previous
work
        <xref ref-type="bibr" rid="ref1">(Green et al. 2019)</xref>
        , we analyzed arguments in
expert-written reports on international affairs in terms of
argument schemes. Argument schemes were originally
proposed by argumentation theorists to describe
acceptable, but not necessarily deductively valid, and
possibly defeasible, generic patterns of reasoning used in
law, science and everyday conversation
        <xref ref-type="bibr" rid="ref10">(Walton et al.
2008)</xref>
        . Examples of such patterns include Argument from
Expert Opinion and Reasoning to the Best Explanation.

government’s strategy for increasing Russia’s global
influence

        , we defined a set of schemes
tailored for arguing about the putative intentions of
foreign actors and for responses to their actions. Our goal
was to provide this set of argument schemes to students
and analysts of international affairs. Although the schemes
could be used to analyze the argumentation in existing
reports on international affairs, our intent was for them to
be used as cognitive building blocks for constructing new
arguments from collected evidence. To further support
argument construction, we developed an argument
diagramming tool, AVIZE (Argument Visualization and
Self-Evaluation), that provides this set of argument

schemes. Anticipatory thinking (AT) is defined in the call
for papers as “the deliberate and divergent exploration of
relevant possible futures.” We contend that the process of
AT should include making arguments for the hypothesized
futures and challenging those arguments. In this paper, we
define an intentional argument scheme for AT and
propose that an argument diagramming tool can be used to
support individual or collaborative construction,
evaluation, and communication of arguments in AT.

      <title>AVIZE’s Argument Schemes</title>
      <p>AVIZE provides a set of argument schemes tailored to
international affairs for constructing arguments in this
domain. For example, the Plan Distraction scheme is
defined as follows. (Capitalized terms such as Actor and
Protagonist are place holders for countries used so that the
schemes can be applied to many different situations, not
just the cases we analyzed when defining the schemes.)</p>
      <p>
        An example of this type of argument appeared in
        <xref ref-type="bibr" rid="ref11">(Weinberger 2016)</xref>
        : Putin has kept international attention
riveted on Russian operations in Syria while escalating
military deployments and political operations across
Europe, the Middle East, and Asia. (The conclusion, that
Putin/Russia does not want the U.S. to oppose the military
deployments and political operations, is implicit.)
      </p>
      <p>Argumentation theorists have proposed posing critical
questions associated with each argument scheme as a
means of challenging an argument. In AVIZE, all of the
schemes include two critical questions: How reliable is the
source of each premise? How likely is each premise? In
addition, the Plan Distraction scheme described above
includes the questions: In the Actor’s view, are the
consequences of Acts/Other Acts acceptable?</p>
      <p>We manually analyzed the 33-paragraph article on
Russia’s global strategy as containing the following
sequence of instances of our schemes: Plan Distraction,
Coercion, critical question of Coercion, Resist Coercion,
Plan Deception, Inferred Plan, Coercion, Increasing
Boldness, Coercion, Inferred Plan, Inferred Plan, Resist
Coercion, Practical Reasoning, Avoid Negative
Consequences, Avoid Negative Consequences, and
Practical Reasoning. Schemes that we identified in other
articles include Inferred Positive/Negative Appraisal and
Behavior Pattern. (While most of the scheme names are
suggestive of their purpose, it should be noted that the
name ‘Practical Reasoning’ is used in argumentation
theory to refer to an argument for a plan of action.) Since
the schemes were derived from analysis of expert-written
reports, they should be helpful to students and analysts in
creating arguments of their own or for analyzing the
arguments of others.</p>

    <sec id="sec-3">
      <title>New Argument Scheme for AT</title>
      <p>Although the scheme set developed for AVIZE was not
based on analysis of examples of anticipatory thinking,
two of the schemes – Increasing Boldness and Behavior
Pattern – could be used for AT. Here we propose that by
manually analyzing examples, additional schemes useful
for AT could be identified. For example, now we will
consider a report written several years ago warning of a
Russian attempt to influence the election of a pro-Russian
government in the Ukraine. The report noted that a large
march of Orthodox supporters was headed to the capital,
where they would be met by Nationalist supporters. It
stated that there was evidence that the march had been
infiltrated by provocateurs and predicted that clashes
between the two groups would ensue, leading to a loss of
popular support for the current anti-Russian government,
resulting in the election of a pro-Russian government.</p>
      <p>This anticipation of possible future events could be
modeled with a chain of arguments, each of which can be
analyzed in terms of the Intentional Cause to Effect
(IC2E) scheme, which we define as follows.</p>
      <sec id="sec-3-1">
        <title>Intentional Cause to Effect (IC2E)</title>
        <p>Premises:
1. Actor has Distal Goal consistent with Value.
2. Actor has Proximal Goal, consistent with that</p>
        <p>Distal Goal.
3. Actor does (will do) Intervention to bring about</p>
        <p>Proximal Goal.
4. Intervention is (will be) feasible in the then present</p>
        <p>Circumstances.</p>
        <p>Conclusion: Actor causes (will cause) Proximal Goal to be
achieved.</p>
        <p>The first prediction, that the two sides will clash, is
based on the argument that Russia (R) has a distal goal of
the election of a pro-R government in the Ukraine, which
is consistent with the value of R having increased global
influence; R has a proximal goal of fomenting clashes
between the two sides (consistent with that distal goal); R
inserted provocateurs into the march in order to bring
about clashes between the two sides when they meet in the
capital; therefore clashes will occur between the Orthodox
and Nationalists in the capital (due to R’s intervention).</p>
        <p>The next prediction, that the current anti-R government
will lose popular support, is based on the argument that R
has the distal goal described above; R has a proximal goal
of loss of popular support for the anti-R government
(consistent with that distal goal); clashes will occur
between the Orthodox and Nationalists in the capital (due
to R’s intervention); therefore the current anti-R
government will lose popular support (due to R’s
intervention). The final prediction, that a pro-R
government will be elected, is based on the argument that
R has the distal goal described above; R has a proximal
goal of the election of a pro-R government (identical to
that distal goal); that the anti-R government will lose
popular support (due to R’s intervention); a group of
proR candidates are available to run for office; therefore a
pro-R government will be elected (due to R’s
intervention).</p>
        <p>This chain of arguments is summarized in Figure 1. By
convention, premises are connected by an upward
pointing arrow to a conclusion. The name of the scheme
(IC2E) appears to the right of the arrow. Entailments of
conclusions are connected by horizontal arrows labeled
‘Entails’. For example, the claim that Russian intervention
will cause the two groups to clash entails the claim that
the two groups will clash.</p>
        <p>Any of the arguments in the chain could be challenged
by providing counterarguments or posing critical
questions. We propose at least the following critical
questions for IC2E. Note that the last three questions refer
to the arguer’s beliefs about the Actor’s beliefs.</p>
      </sec>
      <sec id="sec-3-2">
        <title>IC2E Critical Questions</title>
        <p>1. How reliable is the source of each premise?
2. How likely is each premise?
3. How likely is the Proximal Goal to be achieved by
Actor’s Intervention in the given Circumstances?
Are there factors unknown or ignored by Actor
that may impede its success?
4. In Actor’s view is Proximal Goal likely to be
achieved by Intervention in the Circumstances?
5. In Actor’s view is Intervention feasible in the</p>
        <p>Circumstances?
6. In Actor’s view are the consequences of
Intervention acceptable, or would they inhibit
Actor from performing Intervention?</p>
        <p>Figure 1 shows a challenge to the argument at the
bottom of the tree using the first critical question, i.e., how
reliable is the evidence that R has inserted provocateurs?
Also, the third critical question is shown as challenging
the final (top-most) argument. Furthermore, by adding
IC2E to a repertoire of argument schemes, one may build
complex arguments involving more than just causal
reasoning about an actor’s intentions. For example, as
shown in Figure 1, the premise that R has a distal goal of
the election of a pro-R government could be justified itself
by a Behavior Pattern argument, i.e., based upon R’s past
behavior in other countries. Because of the potential
complexity of the arguments for and against alternative
scenarios, we propose that an argument diagramming tool,
such as one described in the next section, be used to
visually support individual or collaborative construction,
evaluation, and communication of arguments in AT.</p>

      <title>Argument Diagramming in AVIZE</title>
      <p>AVIZE1 was designed to support critical thinking by a
process in which users must evaluate possibly conflicting
evidence from a variety of sources such as different print
or broadcast news organizations; construct a graphical
representation of arguments for a hypothesis using that
evidence and argument schemes; challenge the arguments;
and defend the argument against the challenges. As shown
in Figure 2, potential evidence (with accompanying
metadata such as source) is presented in a panel on the left
side of the screen. Argument scheme definitions and
critical questions are presented in a panel on the right
hand side of the screen. The center of the screen is a
dragand-drop style argument diagram construction workspace.
Figure 3 shows an example of an argument so constructed.</p>

      <title>Related Work</title>
      <p>
        A variety of argument diagramming tools have been
developed to support critical thinking
        <xref ref-type="bibr" rid="ref2 ref9">(Van Gelder, 2007;
Shum et al. 2006; Loll and Pinkwart 2013)</xref>
        . Some
comprehensive intelligence analysis systems also provide
tools for argument diagramming
        <xref ref-type="bibr" rid="ref3 ref4 ref7">(Toniolo et al. 2015;
Pioch and Everett 2006; Schrag et al. 2016; Tecuci et al.
2016)</xref>
        . However none of these tools provide argument
schemes tailored to plan recognition in international
affairs (as in AVIZE) or anticipatory thinking involving
intentions in that domain, e.g., the IC2E scheme.

improve the tool for use in an undergraduate AI Ethics
course using a set of argument schemes tailored to AI
Ethics.

      <title>Conclusion</title>
      <p>The Intentional Cause to Effect scheme defined above
could be added to the scheme set of AVIZE to support
AT. By analyzing further examples of AT, other relevant
schemes could be identified. A graphical tool such as
AVIZE could be used by students and analysts to make
AT assumptions, claims, and challenges visible. In the
long term, using argument schemes for AT such as IC2E
to generate arguments automatically, it may even be
possible to use them to hypothesize future events.</p>
