In 2026, the claim that the "government can read your mind" is a subject of intense legal and scientific debate. While technology has advanced to decode certain types of brain activity, a clear distinction exists between interpreting brain patterns in controlled settings and accessing private thoughts without consent.

As of early 2026, here is the current status of this technology (According to GROK):

1. Technological Capabilities (2025–2026)

• Decoding "Gist" of Thoughts: Researchers have developed "semantic decoders" using fMRI and AI that can reconstruct the general meaning of what a person is hearing or imagining. These systems currently require hours of training on a specific individual's brain data and the subject's active cooperation.

• Speech Restoration: Modern brain-computer interfaces (BCIs) can now detect "inner speech," allowing individuals with speech impairments to communicate by decoding the neural signals of intended words.

• EEG-to-fMRI Synthesis: New deep learning models (such as E2fNet, introduced in early 2025) can synthesize high-resolution brain activity maps from lower-cost EEG data, making advanced neuroimaging more portable and accessible for research and potential monitoring
  

2. Government and Legal Status

• Admissibility in Court: In the U.S., most courts still find fMRI-based lie detection inadmissible because the method is not yet universally accepted by the scientific community.

• Constitutional Protections: Legal scholars, including those in the Hastings Law Journal article you cited, argue that brain scans should be protected by the Fifth Amendment as "testimonial evidence," meaning the government cannot compel a person to submit to a scan that reveals the contents of their mind.

• The "MIND Act": At the federal level, the Management of Individuals’ Neural Data (MIND) Act was introduced in late 2025 to direct the FTC to examine how to define and protect neural data from unauthorized collection.

3. Emergence of "Neurorights"

• State-Level Protection: Several states, including Colorado, California, Connecticut, and Montana, have recently passed laws to protect "neural data," treating it similarly to sensitive biometric data like fingerprints.

• International Standards: In late 2025, UNESCO adopted the first global standard for the ethics of neurotechnology, calling on governments to establish safeguards for the "sanctity of the human mind".
