Could Two Minds Ever Share Information Directly? - Leejohnston - 01-08-2026 Could Two Minds Ever Share Information Directly? Human communication is indirect. Thoughts are converted into: • sound • symbols • gestures • electrical signals in machines But a provocative question sits at the boundary of neuroscience and physics: Could two minds ever share information directly — without language or sensory translation? ⸻ What “direct sharing” would actually mean This does not mean: • telepathy as portrayed in fiction • magical mind reading • thoughts jumping through space unaided It means: • neural information from one brain influencing another • without passing through speech, text, or traditional sensory channels ⸻ What science already allows We already know that: • thoughts correspond to physical brain states • brain activity is electrical and chemical • neural signals can be measured and stimulated Technologies already exist that: • read simple neural signals • stimulate specific brain regions • restore lost sensory functions This establishes that mental states are physically encoded. ⸻ Brain–computer–brain links Early experiments have demonstrated: • brain-to-computer interfaces • computer-to-brain stimulation • simple signal transfer between two brains via machines In these cases: • information is decoded from one brain • transmitted electronically • reintroduced into another brain This is not telepathy — but it is a proof of principle. ⸻ The major obstacles Direct mind-to-mind sharing faces huge challenges: • Neural codes are highly individual • Meaning depends on context and learning • Brains do not use a universal “language” • Conscious experience cannot be directly copied Even if raw data were transferred, interpretation would differ. ⸻ Could physics allow something deeper? Some speculative ideas ask whether: • brains could synchronize dynamically • shared rhythms could carry information • coupling could occur through unknown physical channels At present, there is no evidence for this. But absence of evidence is not evidence of impossibility — only of limits. ⸻ What this does NOT imply This does not imply: • psychic powers are real • minds communicate without physical interaction • current physics is violated Any real mechanism would still obey: • causality • energy conservation • known physical constraints ⸻ Why the question matters If minds could share information directly: • communication would be fundamentally transformed • privacy and identity would be redefined • collective cognition could emerge Even partial forms would change society. ⸻ Open question Is the isolation of minds a fundamental feature of biology — or simply a technological limitation? And if minds ever do connect, what would still count as “you”?
