What Would Settle It
The question is not unfalsifiable. Here is what primary source evidence would be conclusive.
If you believe you know who wrote the Shakespeare canon, the answer to one question will determine whether your case can be assessed: can you produce a contemporaneous primary source, a letter, manuscript, payment record, or explicit contemporary attribution, connecting your candidate to writing under that name?
Note that the document must record authorship directly, not merely be consistent with it. A contemporaneous sonnet, dedication, or literary allusion that requires interpretation to connect your candidate to the works is not a primary source for authorship; it is a primary source being interpreted. The question is whether the document states a fact or whether you are reading a fact into it.
A literary text cannot authenticate itself: the speaker of a poem is a literary construct, not a witness under oath. Even a genuinely autobiographical poem is not testimony; it is art. Using the speaker's claims as evidence of authorship requires first establishing who the author is, which is exactly what is in dispute. The argument is circular. This applies equally to forensic physical evidence that is consistent with a candidacy but stops short of recording authorship directly.
Spenser used the persona of Colin Clout across multiple works, in The Shepheardes Calender, in Colin Clouts Come Home Againe, and in The Faerie Queene, a transparent self-portrait, extensively documented from external sources, and yet no one argues that Colin Clout's statements within the poems prove Spenser's authorship. We know Spenser wrote them because of evidence outside the poems. The speaker's voice, however autobiographical, is not the proof.
More parallels will not do it. More corroboration of corroboration will not do it. The standard is type, not quantity. One document of the right kind settles what any number of interpretive matches cannot, because it records rather than interprets.
The Shakespeare authorship question is sometimes treated as a conspiracy theory, meaning an argument that can absorb any counter-evidence and is therefore immune to resolution. That characterisation is wrong, so let me state clearly what evidence would be genuinely conclusive. An honest enquiry must be able to answer the question: what would change your mind?
The answer is specific. There are identifiable types of primary source document that would settle the question, at least for any reasonable evaluator. Their absence is what this site documents. Their presence, if found, would change the assessment immediately.

What would settle it: and why specifying it matters
Any serious methodology applied to a historical question must be able to state, in advance, what pattern of evidence would close it. A framework that cannot answer that question is not a framework; it is advocacy that has borrowed the vocabulary of inquiry. On why that willingness is the whole difference between an honest certainty and a closed one, see On Knowing.
The Shakespeare authorship question is a historical and literary problem, not a laboratory experiment. But the same requirement applies. Any methodology applied to the SAQ must be able to answer: what would we expect to see if a given candidate wrote the works? And what pattern of evidence would distinguish that candidate from all others? A framework that cannot answer those questions in advance is not a framework; it is advocacy.
Applying this kind of reasoning to a literary and historical problem is not an import of foreign method. It is what literary historians do when working carefully. The SAQ is an empirical question: it asks what happened, among real people and real documents, in documented history. Stating in advance what would close the question is not scientism. It is the minimum condition for honest enquiry into any question of fact, and a methodology that does this is harder to dismiss as advocacy than one that does not.
The same standard applies to every candidate. Two conditions must be met simultaneously to settle the question. The first is a primary source document connecting a named individual to writing under the Shakespeare name. The second, required for any alternative candidate, is an account of Shakspere of Stratford: why his name appeared on the title pages, what his role was, and why he left no primary source evidence of a literary career of any kind. A theory that satisfies the first condition without addressing the second has not settled the question; it has redistributed it. The frameworks this site applies are tools for assessing the state of play in that document’s absence; they can narrow the field and raise or lower the probability of a given candidacy, but they cannot substitute for meeting both conditions.
Stated as an asymmetry: the authorship question and the Stratford anomaly collapse into a single problem only if the document names Shakspere himself, the attribution closes and the missing literary record is supplied in the same stroke. A document naming any other candidate closes the attribution and leaves the anomaly standing, sharpened: an unexplained absence becomes an unexplained presence. One discovery would end the enquiry; the other would end only half of it. This distinction is stated in full under One Unresolved Condition on the Two Frameworks page.
What the paper trail framework requires: a personal primary source document, produced during the candidate’s active period, connecting them to the act of writing under the Shakespeare name. A letter, a payment record, a manuscript, a contemporary reference from someone in a position to know. For Shakspere, this means a document connecting the man from Stratford to the works. For any alternative candidate, it means a document connecting them explicitly to writing under that name. The standard is identical in both directions. This is the only condition that would settle the authorship question, though, as above, only a document naming Shakspere would settle the Stratford anomaly with it.
What a strong convergence result would look like: the evidence lines converging on one candidate more strongly than on any other, with the convergence driven by primary source evidence rather than inference. Currently no candidate achieves a clean sweep. Convergence that was both broad and primary-source-grounded would constitute a strong result, but convergence of circumstantial and interpretive evidence, however extensive, remains the wrong type.
The silence is a structural problem that any alternative theory must address. The name ‘Shakespeare’ on the title pages was associated with a man apparently embedded in the professional theatre who left no literary trace whatsoever, no letters, no record of books owned, no payments for writing, no literary mourning at death.
Either a document emerges connecting him to the writing, which would close the question in his favour, or a documented comparable pattern is established showing that the silence is not anomalous for a writer with his specific profile. Without one of these two outcomes, the silence remains an open evidentiary problem regardless of how well another candidate scores.
The existence of hundreds of Shakespeare biographies does not satisfy this condition. Most biographies of Shakspere make one of two moves: they use the works as biographical evidence, inferring travel, legal training, or court access from what the plays contain, and then offer the resulting profile as support for the attribution. That reasoning is circular. Or they argue that the primary source silence is normal for writers of the period. Diana Price’s survey of twenty-four of Shakespeare's literary contemporaries shows it is not: every one of them left primary source evidence of a literary career in at least one of Price’s ten categories. Shakspere did not; he is the only one of the twenty-five for whom no such evidence exists. The biographies have not closed the evidentiary gap; they have largely worked around it.
No candidate currently meets all these conditions. That is the honest evidentiary state. Stating it explicitly is what separates a methodology from a brief. The analytical findings drawn from those scores are on the What the Evidence Returns page.

A methodological objection: and the answer to it
The strongest challenge to the closing conditions as defined above runs as follows: this site requires a primary source document connecting a named individual to writing under the Shakespeare name, but if the works were published under a pseudonym with deliberate concealment, exactly that document would never exist, not because the author didn’t write, but because the whole point of the arrangement was to leave no traceable connection. Put plainly: if the arrangement was designed to leave no trace, requiring a document of exactly that kind as the price of admission is not a neutral evidential standard. It is a standard built to exclude the alternative hypothesis regardless of the evidence. That is the trap.
The trouble is that the same reasoning would rescue anything. If missing documents are exactly what you would expect from a pseudonym, then no missing document can ever count against a claim, and every attribution is safe from any evidence brought against it. It is structurally identical to arguing that the absence of evidence for a conspiracy is itself evidence of the conspiracy: the arrangement explains its own undetectability. A methodology that absorbs its own disconfirmation is not rigorous. It is unfalsifiable in the pejorative sense, and an objection that, if accepted, would make the alternative candidacies themselves permanently immune to scrutiny is not a defence of those candidacies.
The comparison group cuts the ground from under the objection at its root. Price’s twenty-four contemporaries left primary source evidence of a literary career in at least one of her ten categories, despite also sometimes publishing anonymously or under initials. Pseudonymity and anonymity were common in the period, yet the documents survived anyway. The absence for Shakspere is not explained by pseudonymity as a general condition of Elizabethan literary life. It is anomalous within a comparison group subject to identical conditions.
The standard is also demonstrably satisfiable. The Audley End forensic attribution, 1,800 Greek and Latin annotations in de Vere’s hand with documented textual correspondences to the Roman plays, is an attempt to meet exactly this kind of primary source standard in a candidate’s own hand. It falls short of the highest bar (it is not a manuscript of a Shakespeare work or an explicit statement of authorship), but it shows the framework is not designed to be permanently unsatisfiable. The sections below specify what would satisfy it. Advocates, researchers and scholars who argue for a specific alternative candidate, are actively attempting to do so. The framework evaluates how close they come. That is falsifiability, not a trap.

For the traditional attribution
Any of the following primary source documents, if authenticated, would substantially change the evidentiary picture for Shakspere of Stratford. Two or more would settle it.
A manuscript (any manuscript) of a Shakespeare play or poem in Shakspere’s own hand. This is the single most direct possible evidence. No such manuscript has been found for any Shakespeare work, in any hand, and after four centuries of motivated searching by scholars on both sides, finding one now is as close to impossible as historical research allows. It is listed here not as a research goal but as the theoretical gold standard, the thing that would settle the question beyond argument if it existed. The more tractable evidence types follow.
A letter in Shakspere’s hand discussing a play or poem he was writing, referencing a character, a plot, a patron, a performance. His surviving handwriting, if the Hand D attribution in Sir Thomas More is accepted, amounts to three pages of a collaborative manuscript. No letter of any kind in his hand has been found.
A payment record connecting him specifically to the act of writing a named work, not performing, not shareholding, not property transaction. A payment from a printer, a patron, or a theatre company for a specific play or poem, with his name attached as author.
A contemporary reference, produced during his lifetime, explicitly naming the man from Stratford as the author of specific plays, from someone in a position to know. Not a reference to the name on a title page, and not posthumous testimony. A document produced while he was alive to confirm or deny it.

For any alternative candidate
The standard is identical. The same type of evidence that would settle it for Shakspere would settle it for any alternative candidate. This symmetry is the governing principle.
A manuscript of any Shakespeare play or poem in their hand. The same caveat applies: after four centuries of searching, none exists, and none is likely to be found. It remains the theoretical gold standard. A letter in their hand acknowledging writing under the Shakespeare name, or discussing the works as their own. A will, diary entry, or private correspondence explicitly attributing the works to them, produced by someone with direct knowledge. A primary source connecting them to the publication of a Shakespeare work, a contract, a payment, printer’s correspondence identifying them as the author.
The Audley End forensic attribution, over 1,800 Greek and Latin annotations in books at Audley End House attributed to de Vere’s hand, with documented correspondences to the Roman plays, is the closest any candidate has come to this standard. It is primary source evidence in a candidate’s own hand, connected to the Shakespeare canon by textual analysis. It falls short of a manuscript or explicit statement of authorship, but it is the most methodologically rigorous piece of candidate-specific evidence currently in the debate. Full analysis of the Audley End finding.
Thomas North’s annotated manuscripts, identified by Dennis McCarthy and used to argue that North wrote source plays later revised into the Shakespeare canon, represent a different but comparably rigorous type of primary source argument. If the source-text fingerprint methodology is validated by independent scholars, it would constitute strong evidence for North’s involvement, though the question of revision versus authorship would remain open.

What would not settle it
More biographical correspondences, for any candidate. A correspondence is consistent with a hypothesis; it does not confirm it. The denominator problem means that any catalogue of correspondences, however large, does not accumulate into a probability. The correspondence problem is examined in full on the Advocates page.
Stylometric attribution studies. These presuppose the attribution they claim to test: the training corpus used to characterise “Shakespeare’s style” is defined by the traditional attribution. A stylometric study cannot independently confirm that attribution without circularity. What stylometrics can do, usefully, is identify collaborative passages within a work already attributed to Shakespeare. It cannot settle who “Shakespeare” was.
Cryptographic claims. No Baconian cipher, acrostic, or numerical code embedded in the Folio has been verified by an independent cryptographer. The methodology is not replicable and the conclusions are not falsifiable by the normal standards of cryptanalysis.
Arguments from possibility. It is not impossible that Shakspere made undocumented trips to Italy, acquired undocumented legal training, maintained undocumented literary friendships. Possibility establishes only that a hypothesis has not been disproved; it says nothing about probability.
Arguments from tradition. Four centuries of attribution is a sociological fact, not an evidentiary one. Traditions can be wrong, and the question of whether this one is supported by primary source documentation is precisely what this site examines.
Advocacy inference. A documented fact about a candidate, Bacon employed writing assistants; de Vere annotated books; Marlowe was a Cambridge scholar, is used as a stepping stone to an undocumented conclusion about the Shakespeare works. The documented fact is real; the Shakespeare connection is inferred, not recorded. The inference may be plausible, but plausibility is not evidence. Advocacy inference is the correspondence problem applied to biography: it accumulates real observations into a conclusion the observations do not reach.
