Mental privacy refers to the right of individuals to keep their thoughts, feelings, and mental processes private. This concept emphasizes the importance of protecting one's inner experiences from external scrutiny or intrusion, ensuring that personal mental space is respected. In an age of advanced technology, concerns about mental privacy have grown, especially with developments in neuroscience and brain-computer interfaces. These technologies raise questions about how thoughts and emotions might be accessed or manipulated, highlighting the need for ethical guidelines to safeguard mental autonomy and privacy.
