Stochastic terrorism initially referred to a method of mathematically predicting overall risk of a terrorist attack by using various indicators such as inciteful speech by pundits, politicians, or various leaders. A later use of the term is the accusation of a political or media figure publicly demonizing a person or group in such a way that it inspires supporters of the figures to commit a violent act against the target of the speech. Unlike
incitement to terrorism, this is accomplished by using
indirect, vague, or coded language that allows the instigator to
plausibly disclaim responsibility for the resulting violence. A key element is the use of social media and other distributed forms of communications where the person who carries out the violence has no direct connection to the users of violent rhetoric.
Etymology and related terms
Stochastic describes something random, involving chance or probability.[1][2]
Terrorism involves an unlawful use of violence or intimidation to further political, social, or ideological goals.[3]
Defining features
Although stochastic terrorism is considered an academic term without a formal legal definition,[4] it is differentiated from other forms of terrorism due to its public, indirect, and seemingly random nature.
Speech: A public figure or group disseminates violent, inflammatory rhetoric via mass-media, directed at people or groups of people, sometimes suggesting or legitimizing the use of violence.[4] This speech tends to be
protected due to the use of ambiguous coded language, dog whistles, jokes, hints, and other subtext in statements that fall short of a criminal threshold for causation.[5][6][4] Other themes identified include black and white good vs. evil narratives[7] as well as painting an enemy as a mortal threat, which have been compared to the radicalization techniques used by terrorist groups.[8][9] These attacks are often repeated and amplified inside a
media echo chamber.[10][11]
Speaker(s): Typically the speaker is an influential political or media figure, who is referred to as the "stochastic terrorist" for his or her alleged indirect culpability for the attack.[12][11][4] The instigator(s) or "stochastic terrorist(s)" may or may not knowingly use this technique to attack and intimidate enemies, nonetheless, the effect remains the same. The public figure can plausibly disclaim any subsequent attack, as their words were not an explicit call for violence, and because of the lack of a direct organizational link between the instigator and perpetrator of the attack.[13][4] The public figure cannot be prosecuted for his or her statements so long as they do not meet the legal definition of incitement. This is the key distinction between stochastic terrorism and other forms of terrorism. In the U.S., the 1969 Supreme Court case Brandenburg v. Ohio held that violent, inflammatory speech cannot be criminalized unless it is intended to, and likely to, result in
imminent lawless action.[5] However, Kurt Braddock warns that speech can be quite dangerous even if legal.[12]
Inspiration: An individual or group, without any ties to known terrorist groups, hears the speech and becomes motivated to commit violence against the target of the speech, believing it will further a political or ideological goal.[5][14]
Attack: An attacker commits an act of terrorism that could include physical violence, threats, or other acts meant to harm, instill fear, intimidate.[12] The victims may receive or fear physical attacks, (online) harassment, and death threats.[15] This can have a chilling effect, as many victims do not have the resources for adequate security.[16]
Probability: While difficult to predict each individual act of violence due to the disconnected chain of causality, the speech makes threats and terror attacks more likely. These attacks observed as a collection have a statistically valid relationship, even if individual attacks are too random (
stochastic) to predict precisely.[17]
Origin and popularization of the term
In 2002, the term was first used by Gordon Woo to describe a process to quantify risk of a terrorist attack.[4][18][19][20]
Credit for defining the term has also been given to the blogger, G2geek, on the
Daily Kos platform in 2011, when defining it as "the use of mass communications to stir up random
lone wolves to carry out violent or terrorist acts that are statistically predictable but individually unpredictable", with plausible deniability for those creating media messaging.[4][21][22] The article covered the
2011 Tucson shooting.[12]
As of 2016, "stochastic terrorism" was an "obscure" academic term according to professor David S. Cohen.[23] During an August 9, 2016 campaign rally, then-candidate
Donald Trump remarked "If [Hillary Clinton] gets to pick her judges, nothing you can do, folks. Although the
Second Amendment people, maybe there is. I don't know." These comments were widely condemned as instigating violence, and described by Cohen as "stochastic terrorism", further popularizing the term.[24][23][12]
Counterterrorism techniques such as
attitudinal inoculation can help explain to a broad audience how radicalization and manipulation works, helping to blunt the impact of messages that increase violent tendencies.[12][9] Seth Jones argues that labeling domestic terrorist groups, similar to labeling of international groups, would be helpful, although he acknowledges that most right-wing violence is perpetrated by
lone wolves.[25]Rachel Kleinfeld advocates for increasing the penalties of violent actions or threats against elected officials, election workers, and other essential personnel for the functioning of a democracy to a specially-protected class similar to how hate crimes are classified.[26]
Incidents
The 2009 murder of
George Tiller has been described as an example of stochastic terrorism, as many conservative news opinion shows and talk radio shows repeatedly demonized him for his administration of post-viability abortions.[24][27][23]
The perpetrator of the October 2022
attack on Paul Pelosi stated he was looking for
Nancy Pelosi and hoping to intimidate other Democratic lawmakers, actions that have been described as stochastic terrorism.[9][7][39]
