Fact check: What percentage of mass shootings in the USA are linked to far-right ideologies?

1. Summary of the results

The analyses provided suggest a significant link between far-right ideologies and mass shootings in the USA. According to the source ^[1], the far-right has been responsible for the overwhelming majority of extremist and ideologically motivated killings in the United States for ten consecutive years, which suggests a strong link between far-right ideologies and mass shootings ^[1]. Additionally, the source ^[2] reports that all extremist-related murders in 2022 were committed by right-wing extremists, with 21 of the 25 murders linked to white supremacists, indicating a significant percentage of mass shootings are linked to far-right ideologies ^[2]. The source ^[3] also found that the number of U.S. mass killings linked to extremism over the past decade was at least three times higher than the total from any other 10-year period since the 1970s, with all extremist killings in 2022 linked to right-wing extremism ^[3]. Furthermore, the source ^[4] provides data on politically motivated killings, stating that right-wing extremists have caused more deaths than left-wing extremists, with 76% of deaths from 2015-2024 attributed to right-wing extremists ^[4]. The source ^[5] also reports that over 80% of extremism-related murders in the US in 2022 were committed by white supremacists, which could imply a significant percentage of mass shootings are linked to far-right ideologies ^[5].

• Key findings include:
• A significant link between far-right ideologies and mass shootings
• Right-wing extremists have caused more deaths than left-wing extremists
• The number of U.S. mass killings linked to extremism has increased over the past decade

The exact percentage of mass shootings linked to far-right ideologies is not explicitly stated in the analyses, but the cumulative evidence suggests a substantial proportion.

2. Missing context/alternative viewpoints

While the analyses provide significant evidence of the link between far-right ideologies and mass shootings, there are some missing context and alternative viewpoints that need to be considered. For example, the source ^[6] discusses various incidents of far-right extremism and violence, but does not provide direct information on the percentage of mass shootings linked to far-right ideologies in the USA ^[6]. The source ^[7] discusses the growing trend of nonideological terrorism and the influence of online networks on mass violence, but does not provide a specific percentage of mass shootings linked to far-right ideologies ^[7]. The source ^[8] provides a comprehensive database of US mass shootings from 1966 to 2019, but does not specifically address the percentage of mass shootings linked to far-right ideologies, focusing instead on psychosocial histories and motivations of mass shooters ^[8].

• Alternative viewpoints that need to be considered include:
• The role of nonideological terrorism and online networks in mass violence
• The psychosocial histories and motivations of mass shooters
• The potential for other ideologies or factors to contribute to mass shootings.

3. Potential misinformation/bias in the original statement

The original statement asks for the percentage of mass shootings in the USA linked to far-right ideologies, but the analyses provided do not give a clear answer to this question. However, the cumulative evidence suggests that a significant proportion of mass shootings are linked to far-right ideologies. The sources ^[1], ^[2], and ^[3], which are likely to benefit from emphasizing the link between far-right ideologies and mass shootings, provide the most direct evidence of this link ^{[1] [2] [3]}. On the other hand, the sources ^[6], ^[7], and ^[8], which may benefit from presenting alternative viewpoints or missing context, provide less direct evidence or focus on other aspects of mass shootings ^{[6] [7] [8]}. Therefore, it is essential to consider the potential for bias or misinformation in the original statement and to evaluate the evidence from multiple sources.
