For 20 years, ISD has delivered field-leading threat detection, analysis and real-world strategies to combat terrorism, extremism and authoritarianism - in all their ideological forms.

Recommender Systems and Algorithms

ISD’s research explores how algorithms and generative AI can amplify terrorist content as well as weaponised hate and influence operations across online platforms. This offers valuable insights into potential risks to democratic processes and extremist indoctrination. Our advisory work on social media algorithms explores solutions to these challenges including changes to policies and platform designs, as well as greater transparency through mechanisms including algorithmic audits.
