The real lesson is not that hallucinations cannot be reduced. It is that no closed model should ever be treated as an unlimited source of truth.

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

The paper does not prove that every hallucination is unavoidable or that an LLM is “mathematically guaranteed to lie.” It argues that no closed computational system can guarantee correct answers across every possible problem.

100

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

If it requires exact verification, provide calculators, databases, formal checkers, or other tools. If the system cannot reliably perform the task, it should express uncertainty or refuse instead of inventing an answer.

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

The paper ends with a principle called Computational Class Alignment: Match the difficulty and information requirements of a task to the actual capabilities of the system attempting it. If a task requires current facts, give the model retrieval.

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

The paper’s second proposed route is continuous learning, described as an “internalized oracle” that allows a system to update itself through interaction and feedback. Both approaches increase the system’s capabilities, but neither makes it universally infallible.

100

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

Search results can be incomplete, outdated, irrelevant, or false. The model can also misunderstand accurate evidence. Retrieval expands what the system can access, but it does not guarantee correctness.

100

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

The paper models Retrieval-Augmented Generation as a form of oracle access. By consulting information outside its parameters, a system can answer questions that a closed model cannot. But ordinary RAG is not an oracle of absolute truth.

120

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

But under the paper’s framework, they cannot guarantee perfect accuracy across every possible input. The researchers call this a hierarchy of hallucination inevitability. They also describe two possible escape routes. The first is external retrieval.

100

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

No finite model can store every possible fact, reconstruct arbitrary information it has never received, or solve problems that are mathematically undecidable. More training and larger models may reduce hallucinations on real-world tasks.

100

Jainam Parmar @jainamparmar.bsky.social · 01/10/2026

Its conclusion is narrower, but more defensible, than “hallucinations can never be fixed.” For any fixed model relying entirely on its internal parameters, there will always be some questions it cannot answer reliably.

RESEARCHERS MATHEMATICALLY SHOWED WHY A CLOSED LLM CANNOT BE CORRECT ABOUT EVERYTHING The paper models an LLM as a probabilistic Turing machine and examines it against three fundamental limits: → Diagonalization → Incomputability → Information theory

The evidence supports a more precise conclusion: During childhood, sustained instrumental practice can shape developing brain structures involved in coordinating information and movement across both sides of the body.

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

An earlier 2005 review reported improvements in motor and auditory abilities, but said broader transfer effects in mathematics, verbal skills, and spatial reasoning were still uncertain.

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

The studies did not prove that the change is permanent after someone stops playing. They also did not show that a larger corpus callosum automatically produces faster thinking, superior verbal memory, or better performance across unrelated tasks.

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

However, those studies could not establish whether music created the difference or whether people with different brains were more likely to become musicians. The longitudinal study offered stronger evidence that intensive childhood practice can influence how this pathway develops.

110

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

That detail matters because the finding was associated with sustained practice, not merely being enrolled in music lessons. Earlier cross-sectional studies had also found that professional musicians who began training before age seven had larger anterior corpus callosum areas than non-musicians.

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

After 29 months, the high-practice group showed significantly greater development in a section of the corpus callosum connecting premotor and supplementary motor areas. Practice intensity also predicted the amount of structural change and improvement on a motor-sequencing task.

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

→ High practice: two to five hours each week → Low practice: one to two hours each week → Control group: no instrumental training At the beginning, researchers found no significant differences in corpus callosum size between the groups.

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

Researchers led by Gottfried Schlaug followed 31 children between five and seven years old for approximately 29 months. Eighteen children received instrumental lessons, while 13 received no instrumental training. The children taking lessons were separated according to how much they practiced:

100

Jainam Parmar @jainamparmar.bsky.social · 16/09/2026

Playing an instrument places unusual demands on that connection. A musician may read notation, track rhythm, listen to the resulting sound, and coordinate different movements with both hands at the same time.

CHILDREN WHO PRACTICED AN INSTRUMENT INTENSIVELY FOR 29 MONTHS DEVELOPED A MEASURABLE CHANGE IN THE BRIDGE BETWEEN THEIR BRAIN’S HEMISPHERES The corpus callosum is the major bundle of nerve fibers connecting the brain’s left and right hemispheres.

Medical education has relied on largely flat materials for more than a century. This experiment shows what happens when educational tools are designed around how anatomy is actually understood, rather than simply how it fits onto a page.

100

Jainam Parmar @jainamparmar.bsky.social · 10/09/2026

That matters because understanding anatomy requires more than memorizing labels. Students must understand where structures sit, how they overlap, and why their appearance changes as a scan moves through the body.

100

Jainam Parmar @jainamparmar.bsky.social · 10/09/2026

A developer spoke with medical students, identified these problems, and used GPT-6 Astra to build one tool that connects all three. Students can move between the familiar anatomy diagram, the corresponding CT slice, and the complete 3D relationship without rebuilding the connection.

100

Jainam Parmar @jainamparmar.bsky.social · 10/09/2026

→ Textbook diagrams flatten three-dimensional organs into a single view → CT slices feel disconnected from the anatomy diagrams students memorize → Reading a scan requires tracking patient orientation, slice direction, and changing organ shapes simultaneously

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

That matters far beyond games. Companies are preparing to give AI agents control over complex workflows, financial operations, and autonomous systems. Making these agents smarter may not be enough.

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

The researchers describe this as an attention-allocation and execution problem. A model can reason brilliantly about the current moment while still failing to maintain awareness, remember commitments, and follow through over hundreds of steps.

100

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

They would record commitments such as “found a second city” or “check victory progress,” then fail to execute them within the next 10 turns. Only 48.2% to 65.8% of stated commitments were carried out across the models with enough data to analyze.

100

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

First, the agents failed to monitor critical information. In 7 of 20 defeats, a rival was visibly approaching victory, but the model never checked the available victory data during the final 20-turn warning window. The threat was detectable. The agent simply failed to retrieve it.

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

Civilization VI requires constant coordination across economics, science, diplomacy, expansion, and warfare. Across 23 full-game runs, two failures repeatedly appeared.

110

Jainam Parmar @jainamparmar.bsky.social · 08/09/2026

Researchers made Claude, GPT, Gemini, and Kimi play Civilization VI for hundreds of turns. The results exposed a major weakness in today’s AI agents: They can create impressive strategies, then lose track of them.
