• He warned that writing undermines memory – that it is nothing but a reminder of some previous thought.
• Today, the U.S. is in the middle of a similar panic over TikTok, with critics worried about its impact on viewers’ freedom of thought.
• Brain-computer interfaces, called BCIs, have rightfully prompted debate about the appropriate limits of technologies that interact with the nervous system.
• But as my research on neurorights argues, protecting the mind isn’t nearly as easy as protecting bodies and property.

Thoughts vs. things

• The body has clear boundaries, and things that cross it without permission are not allowed.
• It is normally obvious when a person violates laws prohibiting assault or battery, for example.
• The same is true about regulations that protect a person’s property.

• Instead, a person’s thoughts are largely the product of other peoples’ thoughts and actions.
• Everything from how a person perceives colors and shapes to our most basic beliefs are influenced by what others say and do.
• If I’m not allowed to influence others’ thoughts, then I can never leave my house, because just by my doing so I’m causing people to think and act in certain ways.

Neurotech and control

• People may not be able to completely control what gets into their heads, but they should have significant control over what goes out – and some people believe societies need “neurorights” regulations to ensure that.
• Neurotech represents a new threat to our ability to control what thoughts people reveal to others.
• There are ongoing efforts, for example, to develop wearable neurotech that would read and adjust the customer’s brainwaves to help them improve their mood or get better sleep.

• For example, nations could prohibit companies that make commercial neurotech devices, like those meant to improve the wearer’s sleep from storing the brainwave data those devices collect.
• Yet I would argue that it may not be necessary, or even feasible, to protect against neurotech putting information into our brains – though it is hard to predict what capabilities neurotech will have even a few years from now.
• But one thing is certain: With or without neurotech, our control over our own minds is already less absolute than many of us like to think.
