Understanding and explaining are kind of opposite to each other. When A explains/transmits something to B the (content) explanation travels from A to B but the understanding travels in the opposite direction. A gains understanding because he has explained to B. A needs B.hgm wrote: ↑Thu Sep 18, 2025 10:20 pmI don't buy this "only understood by being explained" thing. But this might be a consequence of 'understood' being an ill defined, or even undefined concept. It seems the one you quoted demands the observed phenomenon should be a causal consequence of something else. But that is basically equivalent to showing the formula that describes the phenomenon is a special case of an even more general formula, e.g. containing more quantities, which had a fixed value in the special case. Like for describing falling objects near the Earth surface formulas that set g=10m/sec2 is sufficient, and the 'explanation' is Newton's law of gravity ant the mass and size of the Earth.smatovic wrote: ↑Thu Sep 18, 2025 1:31 pm...from David Deutsch "The Fabric of Reality":
Our best theory of planetary motions is Einstein’s general theory of relativity, which early in the twentieth century superseded Newton’s theories of gravity and motion. It correctly predicts, in principle, not only all planetary motions but also all other effects of gravity to the limits of accuracy of our best measurements.Let's take a compiler as example, it can produce binary code from source code, can even cross-compile between languages, but the compiler does not understand the given programs, it just applies its "rule book", nothing else.Being able to predict things or to describe them, however accurately, is not at all the same thing as understanding them. Predictions and descriptions in physics are often expressed as mathematical formulae. Suppose that I memorize the formula from which I could, if I had the time and the inclination, calculate any planetary position that has been recorded in the astronomical archives. What exactly have I gained, compared with memorizing those archives directly? The formula is easier to remember – but then, looking a number up in the archives may be even easier than calculating it from the formula. The real advantage of the formula is that it can be used in an infinity of cases beyond the archived data, for instance to predict the results of future observations. It may also yield the historical positions of the planets more accurately, because the archived data contain observational errors. Yet even though the formula summarizes infinitely more facts than the archives do, knowing it does not amount to understanding planetary motions. Facts cannot be understood just by being summarized in a formula, any more than by being listed on paper or committed to memory. They can be understood only by being explained.
To pass the YATT you do not have to be able to understand chess or programming, in theory a brute-force approach (12 monkeys + 12 typewriters + infinity = Shakespeare) can pass the test.

Not everything can be expained; ultimately the Universe is as it is without any cause or reason. Then the best you can hope for is to be able to accurately describe (including predicting) the behavior.
B needs C to gain his own understanding, btw, when B re-organises the content in his own words/structure and transmits it to C. Etc.
Understanding, in this model, is a rearrangement of neurons brought about by carrying out the transmission of the reorganised content.
Important is that understanding follows (time wise) the organisation/transmission of the content, even, if is often the case, that the transmitter is making it up as he goes along (like me now).
No reason, in this model, that an LLM isn’t understanding as it generates text, especially if it “remembers” what it wrote.
