23 of 51 cards from the Recognition of Assumptions deck — real questions with worked answers.

1. In the context of critical reasoning, what is an assumption?

   An assumption is something that is taken for granted or presupposed — an unstated idea that must be true for an argument's reasoning to hold, but which is not explicitly stated in the argument itself.

2. In the Recognition of Assumptions task, how is each item presented to you?

   As a statement (a short passage or claim) followed by a proposed assumption. Your job is to decide whether that proposed assumption has or has not been made in the statement.

3. What is the two-point response scale used in the Recognition of Assumptions section?

   A binary choice: 'Assumption Made' versus 'Assumption Not Made'. You select one of only two options for each statement-plus-assumption pair.

4. What does the response option 'Assumption Made' mean?

   It means the proposed assumption is genuinely taken for granted in the statement — the statement's reasoning depends on it, so the author must have assumed it to be true.

5. What does the response option 'Assumption Not Made' mean?

   It means the proposed assumption is NOT taken for granted in the statement — it is unnecessary to the argument, contradicts it, goes beyond it, or is merely a restatement of what is openly said.

6. What is the core 'necessity test' for deciding whether an assumption has been made?

   Ask: 'Must this be true for the statement's argument to make sense?' If the argument collapses without it, the assumption is made. If the argument survives whether or not it is true, the assumption is not made.

7. State the 'negation' (denial) test for assumptions.

   Negate the proposed assumption. If the negated version destroys or seriously undermines the argument, the assumption was necessary and therefore made. If negating it leaves the argument intact, it was not assumed.

8. Why must an assumption, by definition, be UNstated in the original statement?

   Because an assumption is something taken for granted rather than expressed. If the idea is already written out explicitly in the statement, it is a stated premise, not an assumption.

9. What is the key distinction between 'taken for granted' and 'explicitly stated'?

   Taken for granted = unstated but presupposed by the reasoning (a true assumption). Explicitly stated = openly written in the passage. A genuine assumption is taken for granted; if it is explicitly stated it cannot be the hidden assumption being tested.

10. If a proposed assumption simply repeats information already given in the statement, is the assumption made?

    No — 'Assumption Not Made'. Repeating something the statement already says openly is not an unstated assumption; it is a restatement of an explicit premise.

11. What is a 'hidden premise' and how does it relate to an assumption?

    A hidden premise is an unstated link the argument silently relies on to get from its evidence to its conclusion. In this task, the hidden premise IS the assumption — the missing piece needed to make the reasoning valid.

12. In the everyday claim 'You should take an umbrella; it looks like rain,' what is the hidden assumption?

    That you do not want to get wet (and/or that an umbrella will keep you dry). The advice only makes sense if avoiding getting wet matters and the umbrella is an effective means.

13. What does it mean to 'over-read' a statement in this task?

    To read more into the statement than it actually says — importing extra information, implications, or context that is not there, and then judging the assumption against that invented content.

14. What does it mean to 'under-read' a statement?

    To miss or ignore information that the statement genuinely provides or genuinely depends on, so that a necessary assumption is wrongly rejected or relevant content is overlooked.

15. What is the practical danger of over-reading when judging assumptions?

    You may accept assumptions the author never needed (false 'Assumption Made'), because you have supplied background reasoning of your own that the statement does not require.

16. What is the practical danger of under-reading when judging assumptions?

    You may reject a genuinely necessary assumption (false 'Assumption Not Made') because you failed to notice the gap in reasoning that the assumption was filling.

17. How does an assumption differ from a conclusion?

    A conclusion is the claim the argument is trying to establish (often the main point). An assumption is an unstated supporting idea the argument relies on to reach that conclusion. Conclusions are argued FOR; assumptions are taken for granted.

18. Why is confusing an assumption with the conclusion a common error?

    Because a proposed 'assumption' that actually restates the conclusion is not taken for granted — it is the very thing being argued. Treating the conclusion as an assumption wrongly marks 'Assumption Made' when it should be 'Not Made'.

19. Give the general structure of an argument in terms of premise, assumption, and conclusion.

    Stated premise (evidence) + unstated assumption (hidden link) → conclusion. The assumption bridges the gap between the explicit evidence and the conclusion.

20. For the statement 'Our new manager will improve sales because she increased sales at her last company,' what assumption is being made?

    That conditions are similar enough that her past success will transfer to this company — i.e., what worked before will work here. Without this bridging assumption the inference fails.

21. If a proposed assumption is something the author would actively DISAGREE with, is it made?

    No — 'Assumption Not Made'. An assumption must be something the author takes for granted as true; if it contradicts the argument it cannot be an assumption of that argument.

22. Can a statement of obvious common-sense fact ('the sun rises in the east') be the assumption, even if true?

    Only if the argument actually depends on it. Truth alone is not enough — the test is necessity to the reasoning, not whether the proposition happens to be true in the world.

23. What single question best summarises the whole Recognition of Assumptions task?

    'Is this proposed idea something the author must be taking for granted, without saying so, for their argument to work?' If yes, Assumption Made; if no, Assumption Not Made.
