Fact check: How many mass shootings in the USA between 2020 and 2024 were linked to extremist ideologies?

1. Summary of the results

The analyses provided do not offer a definitive answer to the question of how many mass shootings in the USA between 2020 and 2024 were linked to extremist ideologies ^{[1] [2] [3] [4] [5] [6] [7]}. However, some sources report on specific incidents and trends, such as the growth of far-right extremism and terrorism ^[2], the concern of nonideological terrorism among young people ^[3], and the rise in political violence across the U.S. ^[4]. Additionally, at least seven school shootings or disrupted school shooting plots in the United States were linked to the True Crime Community (TCC) in 2024 alone ^[3]. Furthermore, domestic extremists killed at least 25 people in 2022, with 21 of the murders linked to white supremacists ^[7].

2. Missing context/alternative viewpoints

• The analyses lack a comprehensive count of mass shootings linked to extremist ideologies between 2020 and 2024 ^{[1] [2] [3] [4] [5] [6] [7]}, which is necessary to provide a definitive answer to the question.
• Alternative viewpoints, such as the role of mental health, social media, and other factors in mass shootings, are not fully explored in the analyses ^[3].
• International comparisons and the global context of extremist ideologies are also not considered in the analyses ^[2].
• The definition of "mass shootings" and "extremist ideologies" is not clearly defined in the analyses, which could lead to inconsistencies in the reporting and classification of incidents ^{[1] [4] [6]}.

3. Potential misinformation/bias in the original statement

The original statement may be too narrow in its focus on extremist ideologies, as it does not consider other potential factors that may contribute to mass shootings, such as mental health or social media ^[3]. Additionally, the lack of a comprehensive count of mass shootings linked to extremist ideologies may lead to inaccurate or misleading information ^{[1] [2] [3] [4] [5] [6] [7]}. Right-wing extremists and white supremacists may be overrepresented in the analyses, while other extremist ideologies may be underrepresented ^{[2] [7]}. Overall, a more nuanced and comprehensive approach is necessary to fully understand the complex issue of mass shootings and extremist ideologies ^{[1] [2] [3] [4] [5] [6] [7]}.
