Why is neural data treated as more sensitive than other personal data? · Grey Matter

A recording of the brain can reveal things its owner has not chosen to express and may not know, such as recognition, attention, mood or signs of a neurological condition, and it is produced without a deliberate act the way speech or typing is.

Why is neural data treated as more sensitive than other personal data?

A recording of the brain can reveal things its owner has not chosen to express and may not know, such as recognition, attention, mood or signs of a neurological condition, and it is produced without a deliberate act the way speech or typing is. What it reveals also grows after collection, because a stored recording can be analysed again with better decoders years later. For these reasons ethicists proposed treating it like organs, protected by default and shared only by explicit choice, and Colorado and California classed it as sensitive data in 2024.
