go back to the original data, tabulate the distribution of performances at each age,
Question 5: How could the authors have addressed fairness and relevance?
The authors could have addressed fairness by acknowledging the limitations of their original graphs and considering alternative explanations, including differences in sample sizes and participation across age groups. Rather than assuming aging explains every difference, they could have examined evidence that might challenge their interpretation.
To address relevance, they could have compared performance distributions across age groups and included research that directly examines physical changes associated with aging. This would help separate the effects of aging from differences in participation and provide stronger evidence for their conclusion. The author’s willingness to recognize these limitations demonstrates the importance of evaluating evidence fairly.
