Done loosely, it is a parlour game; with clear constraints, it is an argument.

Name the outcome being explained and choose an alternative supported by evidence. Keep conditions before the change fixed, then trace possible consequences. Later events may change too. The result is a reasoned prediction about an unobserved alternative, not a second record of what happened. **Example.** In an invented port, a council releases stored grain during a shortage. Imagine it keeps the store closed. Keep the earlier harvest and stored grain fixed. Less grain for sale could raise prices, making food harder to afford and increasing protests. Test each link with supply records and accounts of protest motives. Other causes could still bring protests, so this prediction remains uncertain. Later prices must remain free to change. *(drawing: Keep prior conditions fixed at the decision point. Investigate later consequences.)* If removing a cause would prevent the named outcome in an account, that account treats it as necessary. If the outcome would still occur, the cause is not necessary in that account. It could still affect timing, scale, or the route taken. A backdrop is a condition kept fixed in a comparison. It can still matter: a navigable river may enable transport in both alternatives. A pressure develops over time. A trigger is an immediate event proposed to set a process in motion. Calling an event a possible trigger does not show that it caused the outcome alone. Check the causal links and other conditions. Several causes can be necessary within one explanation, so finding one necessary cause does not automatically make it the most important. *(drawing: This invented account proposes a causal chain. The order alone does not prove the links.)* Hindsight means looking back with knowledge of the ending. It can make that ending seem more certain than it was to people then. Judge alternatives using their information, resources, and available choices. A ruler might send an available ship earlier, but could not use a local service that did not exist. A plausible choice also needs evidence about its possible effects. Different outcomes in different places can suggest causes to investigate. A shared decade or poor harvest does not make two places identical. Compare resources, institutions, and decisions before explaining the difference. A policy difference is a possible cause to test, but the contrast alone does not establish its effect or rule out other explanations. **Recap.** Choose an evidence-based alternative, keep prior conditions fixed, and trace later effects. Explain what the comparison suggests and what remains uncertain. *This lesson, its hypothetical examples, questions, worked solutions, and flashcards were written for this dataset.* ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Why Historians Disagree](https://lightmysky.com/learn/history/why-historians-disagree-mt_qSzuXmTEJz) ## Optional connections - [Why Empires Fall](https://lightmysky.com/learn/history/why-empires-fall-mt_ofR2rPlIkQ) - [Telling a Cause From a Coincidence](https://lightmysky.com/learn/history/telling-a-cause-from-a-coincidence-mt_SN1oFNj2gb) - [Counting the Past](https://lightmysky.com/learn/history/counting-the-past-mt_U3Fc_UVWJ5)
