"Stochastic terrorism" is the name given to the link between hate speech
and acts of indiscriminate violence motivated by hate speech
The word "stochastic", meaning "randomly determined", is used due to the unpredictable nature of the violence: the more a political discourse targets a specific group, the more likely that group is to become the victim of violent attacks and even terrorism, but the specific details of the violence which might happen cannot be predicted until it is too late
Case study: Trumpism in the USA
The most well known case of stochastic terrorism in the USA is the January 6 insurrection
. Former president Donald Trump
rejected his loss in the presidential elections, and kept claiming that the election results were the consequences of fraud, that his opponent had "stolen" the presidency from him. Further escalating his discourse, he suggested enacting martial law, and called for his supporters to protest
When his supporters actually stormed the Capitol building on January 6th, leading to 5 dead and over a hundred injuries, Donald Trump did not intervene, rather silently waiting for the events to unfold. Two years later, a report came to the conclusion that, despite his lack of direct involvement, he was responsible for this attempted coup and the resulting casualties
Much less talked about, many other acts of stochastic violence have been motivated by Donald Trump's hate speech
. They did not solely target his political opposition, but also several groups of people, which he constantly demonized and "othered". For example, a year after repeatedly calling COVID-19
the "China virus", over 9000
acts of anti-Asian violence had been reported in the USA
Not so random?
Despite the randomness implied by the word "stochastic", the choice of targets is always very deliberate.
In 2019, a man opened fire in a mosque in Christchurch, New Zealand, killing 51 people and injuring 40
, his manifesto revealed that the attack had been planned for years, with the target location selected months prior.
In 2019 and 2022, two related mass shootings happened in the USA. One, in El Paso, killed 23 in a Hispanic night club
. The other one, in Buffalo, killed 10 black people in a supermarket
. Despite never having met or interacted with the Christchurch shooter, both were regulars of the same Internet communities, influenced by the same media, supporters of the same fringe politicians and political theories, and all three ended up carrying similarly motivated terrorist attacks
When hate speech encourages violence, there is no randomness in the choice of targets. This is why it came as no surprise when, in 2023, supporters of former Brazilian president Jair Bolsonaro stormed the country's Supreme Court and National Congress
. Jair Bolsonaro had been using the same type of discourse that Donald Trump used before the January 6 capitol attacks, and it eventually led to a similar result: a violent coup attempt with a toll of over 80 injured
Since the late 2010s, far-right
terrorism has been on the rise in high income countries, becoming a major concern in the 2020s. Quantifying this rise, the Global Terrorism Index found a 320% increase in far-right terrorism in high income countries between 2015 and 2019
In the United Kingdom, far-right terrorism became the main source of counter-terrorism referrals in 2021
. In France, 1300 people were under far-right terrorism related surveillance in 2022
. In Germany, far-right terrorism became the biggest extremist threat in 2022
Given the increasing visibility of far-right politicians spreading white nationalist
speech in media, it comes as no surprise that these acts of violence are on the rise. Since individual acts of stochastic terrorism are hard to prevent
, this wave of far-right violence will keep happening as long as hate speech is normalized, widespread, and even encouraged in mainstream media and political spheres
