Research indicates that children who eat breakfast regularly tend to perform better academically than those who frequently skip it. Therefore, schools should implement mandatory breakfast programs to improve students' academic performance. Which of the following describes a flaw in the reasoning above?
- AIt overlooks the potential logistical challenges and costs of implementing mandatory breakfast programs.
- BIt fails to consider that some children may already be eating breakfast at home.
- CIt does not specify the type or nutritional quality of the breakfast being consumed.
- DIt assumes that correlation implies causation without considering other factors.
Show answer & explanationAnswer & explanation
Correct answer: D. It assumes that correlation implies causation without considering other factors.
The argument observes a correlation (breakfast and better performance) and then jumps to a causal conclusion (mandatory breakfast will *improve* performance). This is a classic 'correlation does not equal causation' flaw. There could be other factors (e.g., socioeconomic status, parental involvement) that explain both regular breakfast eating and better academic performance.
Why the other options are wrong
- A. This points to practical problems with the *solution* but not a flaw in the *reasoning* that breakfast improves performance.
- B. While true, this doesn't highlight a logical flaw in the *reasoning* that breakfast improves performance, only in the necessity of a mandatory program for *all* students.
- C. This points to a limitation in the evidence, but the core flaw is still assuming causation from correlation, regardless of breakfast quality.
Correlation vs. Causation
The logical fallacy of assuming that because two events or variables are correlated (occur together or in sequence), one must necessarily be the cause of the other, without considering confounding variables or alternative explanations.
- Correlation indicates a relationship, not cause.
- Confounding variables can create spurious correlations.
- Proper experiments are needed to establish causation.
Memory trick: Correlation's a link, but causation needs more than just a blink.
