Worksheet 17 of 30 (56% complete)
Question 1
To properly evaluate whether the diversity training CAUSED the increase in minority hiring, what counterfactual would you need to compare against?
Counterfactual reasoning asks: 'What would have happened otherwise?' Without a baseline or control, you can't isolate the training's effect from other factors (e.g., a tight labor market).
Question 2
Issue: Should the minimum wage be increased to $15/hour?
Argument A: No, because small businesses will be forced to reduce hours or lay off workers to manage increased labor costs
Argument B: Yes, because it's been too long since the last minimum wage increase
Argument C: No, because minimum wage jobs are meant for teenagers, not adults
Rank these arguments from strongest to weakest. Which is the STRONGEST?
Ranking analysis: A: Identifies specific economic mechanism and realistic business response B: Time passage alone doesn't justify policy change without addressing underlying conditions C: Based on outdated assumption; data shows many adults work minimum wage jobs
Question 3
To properly evaluate whether the diversity training CAUSED the increase in minority hiring, what counterfactual would you need to compare against?
Counterfactual reasoning asks: 'What would have happened otherwise?' Without a baseline or control, you can't isolate the training's effect from other factors (e.g., a tight labor market).
Question 4
Proposal: Universal basic income of $1000/month for all citizens
Argument: We cannot afford UBI without massive tax increases
Evaluate this argument across multiple criteria (evidence quality, relevance, comprehensiveness):
Evidence: Moderate, Relevance: Strong, Comprehensiveness: Moderate. Overall: Moderate to Strong
Question 5
Argument: 'Ice cream sales and drowning deaths both rise together. Therefore, ice cream causes drowning.'
What is the logical problem with this argument?
This is a classic 'correlation does not imply causation' fallacy. Hot weather causes both increased ice cream sales and more swimming/drowning.
Question 6
To properly evaluate whether the diversity training CAUSED the increase in minority hiring, what counterfactual would you need to compare against?
Counterfactual reasoning asks: 'What would have happened otherwise?' Without a baseline or control, you can't isolate the training's effect from other factors (e.g., a tight labor market).
Question 7
In this argument: 'All humans are mortal. Socrates is human. Therefore, Socrates is mortal.'
Which statement is the CONCLUSION?
The conclusion is what the argument tries to prove. The premises ('All humans are mortal' and 'Socrates is human') support the conclusion 'Socrates is mortal.'
Question 8
Argument: 'Ice cream sales and drowning deaths both rise together. Therefore, ice cream causes drowning.'
What is the logical problem with this argument?
This is a classic 'correlation does not imply causation' fallacy. Hot weather causes both increased ice cream sales and more swimming/drowning.
Question 9
Argument: 'After we started the job training program, unemployment went down. So the program caused the decrease.'
What important alternative explanation is ignored?
This commits the 'post hoc' fallacy (after this, therefore because of this). Without a control group or considering national trends, we can't establish causation.
Question 10
Issue: Should the minimum wage be increased to $15/hour?
Argument A: Yes, because it's been too long since the last minimum wage increase
Argument B: No, because minimum wage jobs are meant for teenagers, not adults
Which argument is stronger?
Both arguments are weak because they both time passage alone doesn't justify policy change without addressing underlying conditions
Question 11
You test positive for a rare disease (1 in 10,000 prevalence). The test is 99% accurate (1% false positive rate).
What is the approximate probability you actually have the disease?
With 10,000 people: 1 true case, but 100 false positives (1% of 9,999). So probability = 1/(1+100) ≈ 1%. This tests base rate neglect.
Question 12
Question: Should the government increase funding for public schools?
Argument: No, because my taxes are already too high
Is this a strong or weak argument?
Weak argument: Personal opinion without considering broader policy implications
Question 13
In this argument: 'All humans are mortal. Socrates is human. Therefore, Socrates is mortal.'
Which statement is the CONCLUSION?
The conclusion is what the argument tries to prove. The premises ('All humans are mortal' and 'Socrates is human') support the conclusion 'Socrates is mortal.'
Question 14
What missing counterfactual would best test this claim?
The key counterfactual is the 'no-policy' baseline. If jobs would have grown by 50,000 anyway due to economic recovery, the tax cut had no effect.
Question 15
Argument by analogy: 'Social media causes mental health problems in teens, similar to how tobacco causes physical health problems. We regulate tobacco, so we should regulate social media similarly.'
What is the most important DIFFERENCE that weakens this analogy?
A critical disanalogy: tobacco has no redeeming benefits, while social media has legitimate uses. This makes the analogy weaker.
Question 16
Argument: 'Ice cream sales and drowning deaths both rise together. Therefore, ice cream causes drowning.'
What is the logical problem with this argument?
This is a classic 'correlation does not imply causation' fallacy. Hot weather causes both increased ice cream sales and more swimming/drowning.
Question 17
In this argument: 'All humans are mortal. Socrates is human. Therefore, Socrates is mortal.'
Which statement is the CONCLUSION?
The conclusion is what the argument tries to prove. The premises ('All humans are mortal' and 'Socrates is human') support the conclusion 'Socrates is mortal.'
Question 18
Context: Corporate board meeting about remote work policy
Argument: Remote work has increased our productivity by 23% while reducing office costs by 40%
In this context, how strong is this argument?
Strong argument in this context: Specific metrics directly relevant to business performance
Question 19
Question: Should the government increase funding for public schools?
Argument: Yes, because education is important
Is this a strong or weak argument?
Weak argument: Too general and vague, doesn't provide specific reasoning or evidence
Question 20
Argument: 'Ice cream sales and drowning deaths both rise together. Therefore, ice cream causes drowning.'
What is the logical problem with this argument?
This is a classic 'correlation does not imply causation' fallacy. Hot weather causes both increased ice cream sales and more swimming/drowning.
