SYNOPSIS

The rapid spread of extremist ideologies through social media, combined with global conflicts and the manipulation of religious content, plays a significant role in online radicalisation. The emotional amplification of conflicts and the distortion of religious teachings underscore the urgent need for stronger social media regulation, enhanced digital literacy, and access to authentic religious guidance. To effectively combat radicalisation, a comprehensive and multi-faceted approach is essential to protect individuals and societies from the harmful effects of extremist ideologies in the digital age.

COMMENTARY

In November 2024, three Singaporeans, influenced by online radicalisation, were detained under the Internal Security Act for attempting to engage in armed violence overseas. Unlike the usual recruitment methods, they were self-radicalised through digital content, particularly those related to the Israel-Hamas conflict.

This incident underscores the growing role social media plays in the spread of extremist ideologies, where radicalisation occurs rapidly through videos, memes, and encrypted messages. The digital age accelerates radicalisation, often making it difficult to detect until violent actions ensue.

So, what makes the digital age uniquely dangerous in terms of radicalisation? How do global conflicts like that between Israel and Hamas contribute to this trend? And, most importantly, how is religious content being distorted to fuel extremism in this age of instant communication?

In this Perspective, the authors introduce a framework for internet users to categorize the virtual platforms they use and to understand the likelihood that they may encounter extreme content online.

The authors first provide a landscape of the online extremist "ecosystem," describing how the proliferation of messaging forums, social media networks, and other virtual community platforms has coincided with an increase in extremist online activity. Next, they present a framework to describe and categorize the platforms that host varying amounts of extreme content as mainstream, fringe, or niche. Mainstream platforms are those for which only a small portion of the content would be considered inappropriate or extreme speech. Fringe platforms are those that host a mix of mainstream and extreme content—and where a user might readily come across extreme content that is coded or obscured to disguise its violent or racist underpinning. Niche platforms are those that openly and purposefully cater to an extreme audience.
