Nassim Taleb’s recent book on Antifragility may have
some implications for understanding actor networks. Taleb suggests a triad of
system types: fragile, robust or resilient and antifragile. Fragile systems are
ones that collapse under stressful events, robust or resilient systems remain
relatively neutral in the face of stressful events, whilst antifragile systems
positively respond, strengthening under stressful events. Within hazards
analysis such a distinction might be very helpful in separating out communities
that are vulnerable to hazards, those that hold their own and those that thrive
in adversity.
Actor network theory, as outlined in an earlier blog, is a
very useful method for mapping actants (human and non-human), their
relationships and how these relationships operate in changing contexts. Leaving aside the complicated and, sometimes
competing, definitions and deep conceptual issues of this approach, there is
much in the simple drawing of nodes and relations that could help in
identifying the basis of antifragile behaviour as illustrated in the simple
network below.
Actants in the network may try to align and co-ordinate the
network of relations to produce the outcome that they desire. Supermarkets put
pressure on farmers to produce vegetables for them, controlling the prices
asked for vegetables, the transport available for vegetables and even finances
by tying farmers into specific contracts. In other words, the supermarkets are
key actants who have extended their co-ordination and alignment of the network
in such a manner as to virtually control how it operates. But is this network
fragile or not?
Questions of fragility and antifragility can be answered
only when the network is stressed, only when an event causes disruption. The
nature of such events will vary with the nature of the network; event
characteristics that cause network disruption will always be context dependent.
This means that it may not be possible beforehand to predict the fragility or
otherwise of a network. It is only when under stress that parts of that network
may buckle or may develop novel means of relieving or even using the stress to
strengthen the network. Likewise, events can be propagated
through the network in a variety of ways, so although one seemingly similar
event may point to a stress point or relationships in the network, once that stressed node is 'fixed',
the next event may pick out and illuminate another, different stress
point.
Antifragile behaviour can result if an actant can exploit
the stress within the network to ensure that their vision or goals for the
network are increasingly likely after the disruptive event. This realignment or
co-ordination of the network could result from taking over the function of
other nodes or exploiting a relationship that enables an actant to more deeply
embed the relationships it needs to achieve its ends as in the figure. A
particular bad year for crops due to drought, for example, could provide an
opportunity for farmers who invested in irrigation methods to dictate prices to
major suppliers or to cheaply buy up the land of farmers who did not invest in
irrigation. The relationships and nodes existed before the disruptive event,
but the multiple impacts (or the multiple manners in which the event plays out
in the network) open up a range of opportunities for antifragile actants. It is
important to note that antifragility is only definable in relation to the
disruptive event (or the multiple manifestations of that event). Similarly,
antifragility is only noticed if actants exploit the disruption to improve or
enhance their own position and power (expressed through alignment and
co-ordination of the network).
It is through actions within the network of relationships
that antifragility and fragility is expressed. It may be possible to begin to
identify some general properties of actants and relationships that may enable
antifragility, but it is only through the expression of these properties by
actant’s actions during and after a disruptive event that such properties will
be identified as important. Future blogs will begin to characterise such
network based properties by exploring the response of actants to specific
disruptive events.
