Can your brain testify against you?
The UN has brought neural data before the General Assembly. The point isn't science fiction. It's the EEG headband you use to meditate.
On 15 October the UN presented a Secretary-General's report on neurotechnology to the General Assembly. It calls for a ban on coercive and abusive uses, and for stronger informed consent, scientific validation, oversight and protection of neural data.
One line stopped me. Data collected by consumer devices, like games, wellness apps and EEG headbands, could be obtained by governments or used as evidence in legal proceedings.
Not science fiction. An app.
We used to think of neurorights as a question about implants and labs. The report says something else: the risk comes from products we buy online. We wear them to sleep better or focus. We accept the terms without reading them. Then those signals end up somewhere.
The report calls neural data "uniquely sensitive personal data". I agree. But sensitivity alone won't protect it if the way in is still the usual click on "I agree".
Measure understanding, don't read minds
In my lab we use EEG and fNIRS. So this question is close to home. We measure how hard it is for someone to read a clause, not what they think. We do it with volunteers, for a stated purpose, with data used to rewrite the text, not to judge the reader.
In Habeas Mentem I try to draw the line like this: understanding can be measured, the mind must not be read. The first use makes law clearer. The second turns the brain into an archive others can search.
The technology doesn't make the difference. The destination of the data does. The same signal can improve a contract or become evidence in court.
What we actually need
Three things, easy to say and hard to do. A clear ban on using neural data against the person who produced it. A purpose limit that can't be unlocked by a blanket consent. And notices designed to be understood, because no one should hand over their brain on a page nobody reads.
In Europe, the GDPR already provides special categories and purpose limits. In the US, some states have passed dedicated laws. But the UN report moves the debate where it belongs: not to privacy, but to the freedom to think without being watched.
Personal reflection, not legal advice.
