Worksheet 21 of 30 (70% complete)
Question 1
Proposal: Implementing a four-day work week nationwide
Argument: People have worked 5 days a week for decades, so we shouldn't change it
Evaluate this argument across multiple criteria (evidence quality, relevance, comprehensiveness):
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 3
Is this argument deductive or inductive? What makes it strong or weak?
Inductive arguments generalize from specific cases. They cannot be 'valid' like deduction; instead, they are stronger with larger, more representative samples.
Question 4
What is the primary weakness in this argument?
Small, non-random sample (n=5) cannot support population-wide conclusions regardless of unanimity.
Question 5
Topic: Should standardized testing be eliminated from schools?
Argument: Yes, because standardized tests narrow curriculum focus and encourage teaching to the test
Which new piece of evidence would most strengthens this argument?
This strengthenss the argument because: Adds robust, longitudinal evidence
Question 6
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 7
Context: Debate in City Council about building a new stadium
Argument: The stadium will create 500 permanent jobs and attract tourism revenue
Which unstated assumption does this argument rely on?
Hidden assumption: The city can afford the upfront investment. Without this assumption, the argument's conclusion may not follow from its premises.
Question 8
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 9
Argument: College isn't worth it because some graduates struggle to find jobs.
Which is the STRONGEST counterargument?
The strongest counterargument uses aggregate data to rebut the anecdotal claim, showing the general trend outweighs exceptions.
Question 10
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 11
Context: Corporate board meeting about remote work policy
Argument: In-person collaboration is essential for innovation and company culture
Which unstated assumption does this argument rely on?
Hidden assumption: Innovation cannot happen remotely. Without this assumption, the argument's conclusion may not follow from its premises.
Question 12
Argument by analogy: 'We ban violent movies for children. Violent video games are similar in their violent content. Therefore, we should also ban violent video games for children.'
What is the STRONGEST counterargument to this analogy?
Interactive vs. passive consumption is a key difference that may make the analogy weak. Good analogical reasoning requires relevant similarities outweigh relevant differences.
Question 13
Argument by analogy: 'We ban violent movies for children. Violent video games are similar in their violent content. Therefore, we should also ban violent video games for children.'
What is the STRONGEST counterargument to this analogy?
Interactive vs. passive consumption is a key difference that may make the analogy weak. Good analogical reasoning requires relevant similarities outweigh relevant differences.
Question 14
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 15
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 16
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 17
Is this argument deductive or inductive? What makes it strong or weak?
Inductive arguments generalize from specific cases. They cannot be 'valid' like deduction; instead, they are stronger with larger, more representative samples.
Question 18
Argument: My neighbor's dog barked before the earthquake. Therefore, dogs can predict earthquakes.
What is the primary logical flaw in this argument?
The flaw is Hasty generalization. Single anecdote doesn't establish a general pattern or causal relationship
Question 19
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 20
Argument: My neighbor's dog barked before the earthquake. Therefore, dogs can predict earthquakes.
Evaluate the logical validity:
Single anecdote doesn't establish a general pattern or causal relationship
