A trigger is the event that immediately sets an outcome off. A longer-term condition is a situation that built up earlier and made the outcome possible or likely. Questions that begin “Why did…” usually reward you for naming both and showing how they connect.
This skill is the first step in causation and supported explanation. Everything in this lesson uses an invented case, so you can practise the method with no particular depth study.
How do you tell the two apart?
Ask two questions about any factor:
- Timing: did it happen just before the outcome, or had it been developing for months or years?
- Counterfactual test: if this factor were removed, would the outcome still have been possible later, or would it never have been possible at all?
A trigger usually fails the second test in a narrow way: remove it and the outcome may come at a different moment or in a different form. A condition fails it more deeply: remove it and the outcome loses its basic setting.
Worked example (invented case)
The following case is invented for this lesson and is not a real event.
In the invented town of Harrowick, the mill workers stopped work on 3 March 1892. The owner had posted a notice the day before cutting weekly pay. Records in this invented case show that pay had fallen from 14 shillings to 11 shillings a week since 1885, and that the mill was the only large employer in town.
Question: Why did the Harrowick mill workers strike in March 1892?
Step 1, list factors: the posted wage cut, the earlier fall in pay since 1885, the lack of other employers.
Step 2, apply the timing question: the notice came one day before. The pay fall built up over seven years. The lack of other employers describes a standing situation.
Step 3, apply the counterfactual test: without the notice, a strike might have come later over another grievance. Without seven years of falling pay and no alternative jobs, a single notice would probably not have caused a walkout.
Step 4, label: trigger = the posted wage cut. Conditions = the earlier pay fall and the lack of other work.
Step 5, write one linked sentence: “The posted wage cut was the immediate trigger, but it led to a strike because pay had already fallen for seven years and workers had no other local employer.”
The mistake to watch for
A common slip is to start the answer at the trigger and stop there.
Mistaken answer: “The workers went on strike because the owner cut their wages.”
This is true in the invented case, but it names only the trigger. It does not explain why a pay cut produced a strike.
The correction is to add at least one condition and connect it, as in Step 5. A second slip is to treat any earlier event as a “long-term cause”. A fact is a condition only if you can explain how it made the outcome more likely.
Check yourself
Use this second invented case. In the invented village of Fennick, a crowd blocked the bridge on 9 June 1810 after the toll was raised the previous week. The bridge was the only route to the market, and tolls had risen steadily for twelve years.
1. Name the trigger.
Show answer
The toll rise announced the previous week.
2. Name one longer-term condition and say why it counts.
Show answer
Either the bridge being the only route to market, or twelve years of steadily rising tolls. Both were in place before the rise and made people likely to react strongly.
3. Write one linked sentence combining both.
Show answer
“The toll rise was the immediate trigger, but villagers blocked the bridge because tolls had risen for twelve years and the bridge was their only route to market.”
Where this leads next
Next, learn to connect a reason to a documented event with evidence, so that each label you give is backed. You can test the whole module with the integrated practice set.
