Claude got a lobotomy and did not fall apart

Anthropic disabled the model’s J-space - the internal zone where Claude holds concepts and intermediate steps.

• Basic autopilot stayed intact - the model kept writing coherently, recalling simple facts, and working with text.
• Complex thinking dropped - multi-step tasks, rhymes, summaries, and knowledge transfer got worse.

Human Parallel

Humans work in a similar way - breathing, grammar, and habits run in the background, while hard problems need attention.

What J-Space Reveals

This zone reveals hidden processes - bugs, fake data, test situations, and manipulation attempts.

Internal thoughts can be swapped - spider became ant, and the answer about legs changed from 8 to 6.

This looks like an early way to separate a model’s automatic processing from its controlled thinking.
