Neurotechnology and Privacy: Governing Thoughts in the Age of Brain Data

A visual metaphor for the mind under surveillance — as neurotechnology advances, even our thoughts may no longer be private.

Introduction

As brain‑computer interfaces (BCIs) and wearable neurotech become more mainstream, a critical question emerges: Who controls our thoughts—and at what cost to privacy?

Emerging Risks

• Mental privacy invasion: Neural data—thoughts, emotions, attention—could be accessed or inferred without consent.

• Commercial & political misuse: Corporations or states might exploit neural data for manipulation or surveillance.

• Limited oversight: Few legal frameworks currently protect against misuse of thought-derived information.

Regulatory Landscape

• Some U.S. states (like Colorado, California, Montana) now treat neural data as highly sensitive under consumer privacy laws.

• Chile has gone further, embedding “neurorights” into its constitution to safeguard mental autonomy since 2022.

• Global norms are still nascent: UNESCO and international experts are beginning to address ethical gaps.

Policy Recommendations

1. Enshrine cognitive liberty: Recognize mental autonomy as a fundamental right.

2. Treat neural data as sensitive personal data: Require explicit opt‑in, limit storage, and mandate deletion.

3. Create oversight boards: Multidisciplinary committees—ethicists, technologists, civil society—should vet neurotech deployments.

4. Lead global standards: The Cyber Institute should convene policymakers to define neurorights and ethical design norms.

Conclusion

Neurotechnology and privacy define the next frontier of digital rights—and the time to govern our thoughts is now.
