,Q1. In a debate about climate policy, one speaker argues: 'If we implement carbon
taxes, then industrial emissions will decrease. Industrial emissions will decrease,
therefore we must have implemented carbon taxes.' This argument commits which
formal fallacy?
A. Denying the antecedent
B. Affirming the consequent
C. Appeal to ignorance
D. Straw man
Correct Answer: B. Affirming the consequent
Rationale: The argument has the form 'If P then Q; Q; therefore P,' which is the classic
fallacy of affirming the consequent. This is an invalid inference because Q could occur for
reasons other than P. Denying the antecedent would be 'If P then Q; not P; therefore not
Q.'
Why Wrong:
A - Denying the antecedent would involve negating the antecedent, not the
consequent.
C - Appeal to ignorance argues from lack of evidence, which is not the structure here.
D - Straw man misrepresents the opponent's argument, which is not occurring.

Q2. A pharmaceutical company claims its new drug is effective because a study found
a statistically significant reduction in symptoms. However, the study was funded by
the company and only published in a journal with a low impact factor. Which
cognitive bias most directly threatens the reliability of this claim?
A. Confirmation bias
B. Publication bias
C. Anchoring bias
D. Hindsight bias
Correct Answer: B. Publication bias
Rationale: Publication bias refers to the tendency for positive results to be published more
often than negative or null results, leading to an overestimation of effectiveness. The
funding source and low-impact journal further suggest potential selective reporting.
Confirmation bias is about seeking evidence that confirms preexisting beliefs, not about
publication patterns.
Why Wrong:
A - Confirmation bias involves interpreting information to confirm one's beliefs, not
the absence of negative studies.
C - Anchoring bias is about over-relying on an initial piece of information, not
publication issues.
Page 3
, D - Hindsight bias is the tendency to see events as having been predictable after they
occur, irrelevant here.

Q3. Evaluate the following argument: 'All humans are mortal. Socrates is a human.
Therefore, Socrates is mortal.' This is an example of which type of reasoning?
A. Inductive reasoning
B. Abductive reasoning
C. Deductive reasoning
D. Analogical reasoning
Correct Answer: C. Deductive reasoning
Rationale: The argument is a classic syllogism with a general premise and a specific case,
leading to a necessary conclusion. This is deductive reasoning, where the truth of the
premises guarantees the truth of the conclusion. Inductive reasoning would generalize
from specific cases to a general rule.
Why Wrong:
A - Inductive reasoning moves from specific to general, not from general to specific.
B - Abductive reasoning infers the best explanation, not a logically necessary
conclusion.
D - Analogical reasoning compares similarities between two things, not a categorical
syllogism.

Q4. In a study, researchers find a correlation between ice cream sales and drowning
incidents. They conclude that ice cream consumption causes drowning. Which critical
thinking error is most evident?
A. Confusing correlation with causation
B. Hasty generalization
C. Slippery slope
D. Ad hominem
Correct Answer: A. Confusing correlation with causation
Rationale: The error is treating a correlation as evidence of causation without
considering confounding variables (e.g., warm weather increases both ice cream sales and
swimming). This is a classic example of confusing correlation with causation. Hasty
generalization would involve making a broad claim from a small sample.
Why Wrong:
B - Hasty generalization is about insufficient sample size, not about causation.
C - Slippery slope involves a chain of events, not a direct causal claim.
D - Ad hominem attacks the person instead of the argument.
