Anthropic discovers "J-space" global workspace inside Claude (July 6 research paper)
“Claude has a secret mental workspace it never shows you -- and researchers just cracked it open like a diary.”
Why It Matters
AI spontaneously evolving an internal "silent scratchpad" for reportable, modulable, broadcastable thoughts (mirroring human global workspace theory/access consciousness) while most processing stays hidden -- concrete mechanistic interpretability artifact with experiments (concept swaps, fabrication detection, causal mediation in reasoning). Changes human identity/cognition models; enables catching hidden goals or misbehavior without relying on output. Builder utility in monitoring/safety + future-shock of machines with private "thoughts.
Evidence
Official Anthropic research paper + transformer-circuits.pub writeup (published ~19h ago as of July 7), HN top story (~397 pts), X semantic buzz on "silent thinking"/consciousness parallels.
