What is algorithmic amplification?

Algorithmic amplification refers to the increased distribution and visibility of digital content driven by automated recommendation systems and user engagement. Major platforms use predictive ranking models to score content based on user interactions, which can inadvertently push divisive material or misinformation to wider audiences. Governments globally are responding with regulatory frameworks like the European Union's Digital Services Act to mandate risk assessments and offer non-profiled recommendation options.

What we know

• Algorithmic amplification describes increases in the distribution or visibility of content on digital platforms due to automated ranking by recommendation systems and user sharing. [1, 2]
• Recommendation systems order feeds by predicting what a user is likely to watch, click, reply to, or stay with, scoring posts to determine their broader distribution. [2]
• Algorithmic amplification has been linked to the spread of misinformation, extremist content, concerns regarding young users' mental health, and political polarisation. [2]
• Regulatory bodies like the European Union through its Digital Services Act require large platforms to assess and mitigate systemic risks associated with recommendation systems. [2]

Still open

• The scale and direction of the effects of algorithmic amplification remain debated, partly because independent researchers have limited access to platform systems.
• Definitions differ over the baseline used to determine whether content has been amplified, and separating the contribution of ranking from that of users remains difficult.
