standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.| second reading | alternatives | an independent re-reading of a facet, recorded whether or not it agrees |

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; 1 of 8 relations here carries that mark. The rest are the tagger’s reading of the sentence quoted beside them.
This record holds no controls. A layer is empty when the tagger recorded nothing in it — which is not the same as the paper having nothing to record.

| mechanisms | mechanisms Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. | mechanisms[0] | the tagger's words | |
| mechanisms | Treating the observer as a communication channel makes the limit measurable: input information is raised until transmitted information stops rising, and that asymptote is the capacity Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. | mechanisms[1] | the tagger's words | |
| mechanisms | Immediate memory holds a fixed number of chunks rather than a fixed number of bits, which is why it behaves unlike absolute judgment Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. | mechanisms[2] | the tagger's words | |
| mechanisms | Because the limit is in chunks, packing more information into each chunk raises how much can be held without raising the count Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. | mechanisms[3] | the tagger's words | |

The sentence is in the paper at the link above. what this limits: the span of perceptual dimensionality: THERE IS NO OBJECTIVE EVIDENCE TO SUPPORT THIS SUSPICION | limitations[1] | the tagger's words | |
| limitations | Some reported channel-capacity values are probably underestimates because data were pooled across subjects before computing transmitted information. Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. what this limits: the channel-capacity values: THESE VALUES ARE APT TO BE SLIGHTLY TOO LOW BECAUSE THE DATA FROM ALL SUBJECTS WERE POOLED BEFORE THE TRANSMITTED INFORMATION WAS COMPUTED | limitations[2] | the tagger's words | |
| limitations | The central theoretical unit, the chunk, is not precisely defined. Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. what this limits: every claim counted in chunks: WE ARE NOT VERY DEFINITE ABOUT WHAT CONSTITUTES A CHUNK OF INFORMATION | limitations[3] | the tagger's words | |
| limitations | The subitizing comparison rests on a guess, since the number-estimation data were never analysed in informational terms. Quotation withheld — this record is not cleared for redistribution.

| limitations | The paper's own closing position is that the recurring seven is probably coincidence, not one underlying limit Quotation withheld — this record is not cleared for redistribution.

Audit 2026-09-28: DOUBTFUL - read against its span and kept, but the span relates memory span to a fixed number of chunks; operationalised-as is a loose reading. also in: span of immediate memory · chunk | concept_edges[4] | the tagger's words | |
| concept_edges | EVIDENCE CORRECTED (RE-GROUNDED) · recoding —causes→ chunk Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. EVIDENCE CORRECTED: RE-GROUNDED. The old span describes WHAT recoding IS - 'There are many ways…' - and names only one endpoint. It carries NO EFFECT CUE AT ALL, so a 'causes' edge standing on it would fail the gate's own causes test today; it predates that rule. The replacement names both endpoints and states the effect: '…recoding INCREASES the bits per chunk'. Both spans are Miller's and both are accurate; the second is evidence for THIS TYPE and the first is not. Selected from an internal tool after reading six offers and DECLINING FIVE - cook2013's candidate carried a glued sentence-case heading, schmidhuber2015's was a contents listing, and grilli2016's and another row of this record's existing spans were STRONGER for their types than the offers (grilli2016's sentence on modular block structure; another row of this record's on a span of a fixed number of chunks). A both-endpoint span is not an improvement if it is weaker evidence for the type. — strength of the relation: 1
Audit 2026-09-28: DOUBTFUL - read against its full span and kept, but endpoint by anaphora: 'this recoding' = recoding the input into a code with fewer chunks (previous sentence). | concept_edges[5] | the tagger's words | |

| content_tags | EVIDENCE CORRECTED (RE-GROUNDED) · about 7 — the limit on the span of absolute judgment and immediate memory Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above. EVIDENCE CORRECTED: RE-GROUNDED. The evidence was THE PAPER'S OWN TITLE - 'Quotation withheld' - which names the quantity and asserts nothing. A title is furniture in the same sense as a reference line: it says what the paper is about. The replacement is Miller STATING the quantity in his own voice, defining the span of absolute judgment and putting it 'in the neighborhood of seven'. The old span survived every check because an internal tool carried a literal 0x08 where a word boundary was meant, so the <h1> was never stripped from the body tags are checked against., measured by the project, verified here against the record's own title field. | content_tags.quantities[0] | 0.85 | the tagger's words |

The published string was in NEITHER copy of the paper. Ours began 'between bits…'; the paper says 'I HAVE FALLEN…'.
