From an interpretive epistemological approach, ideas, norms, and discourses acquire
centrality as objects of analysis. The role of ideas has been recognized in International
Relations by authors of various theoretical currents. Two major meta-theoretical
approaches inform the studies about norms internalization: rationalism and
constructivism (Cortell & Davis, 2000; Boekle, Rittberger, Wagner, 1999; e.g.). From
rationalism, it is argued that international norms modify the actors’ incentives by
providing solutions to coordination problems and reducing transaction costs. In this
context, that implies that adherence to international standards will depend on a cost-
benefit calculation and the possibilities that the rules provide to maximize the profits of
these actors.
On the other hand, in a constructivist sense, it is affirmed that international norms
provide a language and a grammar of international politics, constituting the social actors
themselves through shaping their identities and interests. For constructivism, social
actors are guided by the logic of the appropriate, opposing the assumption rooted in the
rationalist tradition where it is supposed that social action is guided only by the logic of
the consequence. Rationalists read cost-benefit calculation as the leading guide for social
action. At the same time, for constructivists, the logic of what is appropriate implies
recognizing that, for the actors, it is more critical that their practices are recognized, by
other agents and by themselves, as legitimate and appropriate to a given social context
(March & Olsen, 2008). If considerations of “appropriateness” prevail to guide the social
agency, the modalities under which climate change is initially framed as a problem that
define the “adequate” actions to address it will generate dependent trajectories (David,
2007) of these interpretations, impacting on the discourses and the future policy itself.
The latter implies considering international norms as discursive processes (Krook & True,
2010). Recognizing the discursive dimension of the norms allows us to question the
assumption that international norms maintain their essence and meaning unaltered
during internalization. Precisely, the integrity of an international norm can be questioned
after its rhetorical acceptance (Stevenson, 2013). Thus, internalization processes
necessarily imply processes of reinterpretation of the norm based on their dynamism.
Two sources of the norm’s dynamism can be recognized: external and internal ones. The
external dynamism of a norm is generated by the broader universe of existing norms and
the conflicts or alignments between them, that is, the competition that is generated
around the adoption of a particular norm or another potential alternative competitor,
whether in the same thematic area or not (Krook & True, 2010).
The internal dynamism is observed in its potential to establish competition between the
different meanings that the adoption of the norm implies itself. On the other hand, the
internal dynamism of a norm is defined by the connection made between the international
norm and its domestic reception or with the correspondence between said norm and
existing domestic norms. In other words, domestic actors are active agents in
reinterpreting the content of the norm in their adoption and not merely passive recipients
of an international system that modifies them.
To refer to the internal dynamism of international norms, it is necessary to bring up the
complementary concept of normative congruence. This concept refers to the
