A car manufacturing company is facing a class -action lawsuit because of major brake failures. The company’s research department is especially implicated because their published research on the brake systems showed them to be within expected safety standards. The following are expectations of ethical experimentation EXCEPT:
  1. presentation of all results - favorable and unfavorable
  2. full explanation of methodologies used in research
  3. exclusion of important factors that affect experiment results
  4. presenting summaries that do not distort experiment results
Explanation
Answer: C - In ethical experimental design, all important factors that affect results should be included.
Key Takeaway: Research ethics requires researchers to include all important factors that may affect experiment results. In the example of the brake failures, researchers are obligated to include brake performance in high speeds, for example, in their design in an effort to expose potential failures.
