Too little
Dramatic inference: announce a monster because the outline resembles one. Everyone begins explaining an invented creature.
Separate an observed detail from the conclusion you are tempted to attach to it.
A disposition to distinguish what is sound from what merely seems convincing.
Try a practice
At a rehearsal, an enormous horned shadow appears on the wall. Your first explanation is splendid: the costume cupboard contains a monster. Moving the lamp reveals a coat stand with two umbrellas. The shadow was real. The monster was your contribution.
This is an invented illustrative scene.
Discernment gives a detail its proper job. An observation constrains an explanation; it does not automatically name a cause. In a mystery, a wet sleeve may matter greatly, but it still leaves questions about rain, washing and timing. Enjoy proposing an account, then ask which part the detail actually supports. The difference between “I saw” and “I inferred” makes the next question to examine easier to find.
Discernment gives inquiry a firm starting point: something another reader can examine without first adopting your explanation. You can disagree about the coat stand while agreeing about the shadow. That shared ground lets reasons do work that competing certainties cannot.
A good distinction can open a small investigation rather than end it. When a delivery email says an item was delivered, you can separate the recorded status from whether the item reached the intended door, then ask a relevant question through the normal service channel.
Dramatic inference: announce a monster because the outline resembles one. Everyone begins explaining an invented creature.
Discriminating inquiry: describe the outline, then check how the lamp and nearby objects produce it. The account becomes testable.
Endless splitting: refuse to answer the practical question because every description could be more precise. The rehearsal stalls.
A distinction earns its place by making a relevant question answerable. Describe enough to test the explanation, then let the inquiry move on.
Underline one observed event and name two explanations it still permits. Later chapters can discriminate between them.
Distinguish “no reply yet” from “they are angry.” The first is available information; the second needs support.
Attentiveness notices the shadow; Discernment distinguishes its appearance from its cause.
Syntharity assembles the supported details into an account; Discernment tests their individual significance.
Clever suspicion counterfeits Discernment when an ingenious explanation is treated as proof. In the rehearsal, the complicated monster biography adds nothing to the shadow. Discernment asks what would distinguish that story from a coat stand.
Choose a passage in a mystery or an event involving your own belongings. Write mentally two sentences: what you observed, and what you infer. Name one harmless check that could tell you more; leave it unanswered if no appropriate check is available.
Return after the harmless check: did the description stay true when the explanation changed?

John Stuart Mill · A System of Logic, Ratiocinative and Inductive, Volume I
INTRODUCTION.
John Stuart Mill · Project Gutenberg 26495 display edition; original work 1843; text edition to be collated before release
Mill distinguishes an apparent direct perception from an inference. The horned shadow illustrates how quickly a cause can enter a description.
For, the having the idea of anything in our mind, no more proves the existence of that thing, than the picture of a man evidences his being in the world, or the visions of a dream make thereby a true history.
John Locke · An Essay Concerning Humane Understanding, Volume II
1. Knowledge of the existence of other Finite Beings is to be had only by actual Sensation.
John Locke · Project Gutenberg 10616 display edition, described as based on the second edition; Books III and IV
Locke’s comparison separates an imagined account from evidence of its existence. A vivid monster theory still needs something beyond its vividness.
You have drawn the inference, and you must prove the fact.
Anna Katharine Green · The Leavenworth Case
VIII. CIRCUMSTANTIAL EVIDENCE
Eleanore Leavenworth · 1878 novel; Project Gutenberg 4047 display edition
The challenge separates an attractive inference from its support. Reading a mystery gives us a bounded place to examine that difference.
Circumstantial evidence is a very tricky thing …
Arthur Conan Doyle · The Adventures of Sherlock Holmes
IV. THE BOSCOMBE VALLEY MYSTERY
Sherlock Holmes · 1892 collection; Project Gutenberg 1661 display edition
Holmes challenges Watson’s apparently obvious verdict in “The Boscombe Valley Mystery.” A clue’s significance depends on the account connecting it to the event.
Its most common form is that of boldly stating some unproven fact, authoritatively and positively, and then proceeding to use the statement as the major premise of the argument, proceeding logically from that point.
William Walker Atkinson · The Art of Logical Thinking; or, The Laws of Reasoning
CHAPTER XIX. FALLACIES
William Walker Atkinson · 1909 work; Project Gutenberg 41838 display edition
Atkinson describes begging the question. Reasoning from an unsupported premise can look orderly while the foundation remains untested.
He rightly believed me to have made a new nightgown secretly, but he wrongly believed the paint-stained nightgown to be mine.
Wilkie Collins · The Moonstone
CHAPTER V
Rosanna Spearman, in her letter · 1868 novel; Project Gutenberg 155 display edition
Rosanna distinguishes a correct observation from an incorrect identification. The passage makes the extra inference visible rather than treating every discovery as conclusive.
Either you have made some great mistake, or I don’t quite understand you.
Elizabeth Gaskell · North and South
CHAPTER V. DECISION.
Mrs. Hale · 1854–1855 serial; 1855 book; Project Gutenberg 4276 display edition
Mrs. Hale speaks in the shock of learning her husband will leave Helstone. Her words distinguish a mistaken account from a failure to understand it; they are a question to explore, not evidence that she calmly accepts the news.
