Solutions: Putting deductive storylines into practice

Hello again,

Well done for completing this module. It is one of the more difficult ones.
The solutions are outlined  below for you as well as some suggestions for mastering deductive storylines.

Feel free to email us at hello@claritycollege.co if you have any questions.

Regards,
Davina and Gerard

 

Solutions

1. When should you use a deductive storyline?
We gave you five options (below) and the final one is correct. You should use a deductive storyline when your audience needs to know both your recommendation and how to implement it AND when you are certain that your governing idea is correct
When you have a lot of persuading to do

  • When you need to provide an action plan
  • When your audience needs to know both your recommendation and how to implement it in the one piece of communication
  • When you are certain that your governing idea (Answer) is correct
  • Both of the last two options are correct

2. Which deductive storyline works best?

The solution is the last option: Success requires X, you are not equipped to do X, therefore you should develop the capability to do X. The other two options do not lead to a solid conclusion: there is doubt in both.

  • Flawed chain 1: Competitors do X to succeed, you don't do X, therefore you should do X: Just because competitors do X to succeed does not mean it will help you. Your circumstances may be different.
  • Flawed chain 2: Success requires X, you don't do X, therefore you should do X. Just because success requires X does not mean you should do it: the barriers between you not doing it and being able to do it may be too high to enable you to succeed.

3. Which is a sound deductive chain? 
The solution is the first option: “Deductions are only given when receipts are provided, you have not provided receipts, therefore you are not entitled to a deduction.” This chain works because it is logically tight. There are flaws – sometimes small ones – in the chains below, which I have highlighted.

  • Flawed chain 1:Deductions are only given when receipts are provided, you have receipts, therefore you are entitled to a deduction. (Just because you have receipts, does not mean you have provided them.)”
  • Flawed chain 2: Deductions only given when receipts are provided, you have some receipts, therefore you have deductions (Read it closely: this one is loose. There are gaps between the however and therefore points).

4. What is wrong with this deductive storyline?

Governing idea: Like all firefighters, Maude loves swimming

Statement: Maude loves swimming
Comment: Maude is a firefighter
Conclusion: Therefore, all firefighters swim

  1. The argument does not flow from the general to the particular
  2. The comment does not truly comment on the statement
  3. The two ideas above are correct
  4. The conclusion is not specific enough

Solution: The correct answer is 3: The two ideas above are correct. This is because the argument does not flow from the general to the particular and the comment does not truly comment on the statement.

The first two are correct, which means that the third option is the correct answer. The argument does not flow from the general to the particular: Maude loves swimming and Maude is a firefighter are two ideas that are the same kinds of things: they are descriptions of Maude. In light of that, it is also true that the comment does not comment on the statement: They are separate ideas and not connected to each other.
The conclusion is specific enough in the circumstances which means that point three is not true

5. What is wrong with this deductive argument?

Statement: OilyCo's profits are falling in line with the oil price
Comment: The legislative environment in the US is getting tougher for corporates
Conclusion: OilyCo should sell its PNG oil and gas interests

  1. The comment does not truly comment on the statement
  2. The argument does not flow from the general to the particular
  3. The conclusion does not flow from the comment or the statement
  4. All of the above

All of the above is the correct answer.

  • The comment does not comment on the statement: The idea that OilyCo's profits are falling in line with the oil price has nothing to do with a tough legislative environment in the US
  • The argument does not flow from the general to the particular: To start the argument with a point about OilyCo's profits and then lead to a comment about the legislative environment is working from the specific to the general, not the other way around
  • The conclusion is not related to either the statement or the comment
