Fact check: How many mass shootings in the USA have been linked to far-right ideologies since 2010?

1. Summary of the results

The analyses provided suggest that there is a significant link between far-right ideologies and mass shootings in the USA since 2010. According to ^[1], between 2011 and 2022, there were 26 ideological domestic extremist-related mass killing incidents in the US, with 16 of these incidents committed by right-wing extremists, resulting in 89 deaths ^[1]. Additionally, ^[2] and ^[3] report that all extremist killings identified in 2022 were linked to right-wing extremism, with a high number linked to white supremacy ^{[2] [3]}. The data from the Cato Institute and the Anti-Defamation League, as cited in ^[4], also indicates that right-wing extremists have been responsible for the majority of deaths in the United States due to politically motivated attacks since 2010, with 76% of deaths attributed to right-wing extremists from 2015-2024 ^[4]. Furthermore, ^[5] notes that in 2021, domestic extremists killed at least 29 people in the United States, with most of the murders (26 of 29) committed by right-wing extremists, primarily associated with longstanding extremist movements such as white supremacy ^[5]. The majority of the analyses suggest a growing trend of far-right extremist violence, with ^[1] and ^[5] providing specific numbers and statistics to support this claim ^{[1] [5]}.

2. Missing context/alternative viewpoints

While the analyses provide a significant amount of information on the link between far-right ideologies and mass shootings, there are some missing context and alternative viewpoints that need to be considered. For example, ^[6] mentions that experts are seeing a growing trend of nonideological terrorism and the influence of online networks that glorify violence, which may be linked to far-right ideologies, but does not provide a direct number of mass shootings linked to far-right ideologies since 2010 ^[6]. Additionally, the analyses do not provide a comprehensive overview of the motivations and ideologies behind all mass shootings in the USA since 2010, which could provide a more nuanced understanding of the issue. Alternative viewpoints, such as the role of mental health and gun control, are also not fully explored in the analyses. Furthermore, the sources do not provide a detailed analysis of the impact of social media and online networks on the spread of far-right ideologies, which could be an important factor in understanding the growing trend of far-right extremist violence ^{[2] [3]}.

3. Potential misinformation/bias in the original statement

The original statement asks for the number of mass shootings in the USA linked to far-right ideologies since 2010, but does not provide a clear definition of what constitutes a "mass shooting" or "far-right ideology". This lack of clarity could lead to potential misinformation or bias in the response, as different sources may have different definitions and criteria for what constitutes a mass shooting or far-right ideology. Additionally, the sources cited in the analyses, such as the Anti-Defamation League and the Cato Institute, may have their own biases and agendas, which could influence the presentation of the data and the conclusions drawn from it ^{[1] [4]}. It is also possible that the original statement is framing the issue in a way that benefits a particular political or ideological agenda, such as emphasizing the role of far-right ideologies in mass shootings while downplaying the role of other factors, such as mental health or gun control ^[6].
