Call to regulate big tech's engineered manipulation of user behaviour

An article published in The Economist on 29 April 2026 calls for regulatory intervention to curb the ability of major technology firms to manipulate how users behave. The piece, authored by Marie Potel-Saville, explicitly advocates for measures that would prohibit the use of engineered mechanisms designed to rewire the brain's reward system.

The proposal focuses on stopping the deployment of tools that exploit neurobiological pathways to influence human action. By targeting these specific psychological levers, the argument suggests that regulators can prevent big tech from driving user conduct in ways that contradict individual intent.

This initiative emerges within a broader context of growing scrutiny regarding digital ethics and the influence of algorithms on human psychology. The debate centres on the morality of using sophisticated software to alter behavioural patterns on a mass scale.

While the article makes a strong assertion that current mechanisms are capable of rewiring the brain, the source material notes that this claim requires further scientific validation to be treated as established fact. The text presents the situation as a proposal rather than a confirmed historical event, reflecting the speculative nature of the regulatory landscape in 2026.

The specific legislative body or framework intended to enforce these measures remains unidentified in the available reporting. Similarly, the precise legal definition of "engineered mechanisms" in this context has not been fully detailed in the source text.

The call to action highlights a significant shift in how financial and policy institutions may need to view the risks associated with digital platforms. As the debate continues, the focus remains on whether existing regulatory tools are sufficient or if new legislation is required to address these neurobiological vulnerabilities.
