Passage Summary: People who like taking risks usually have fewer rules, while people who want to be liked have more rules. Since more rules lead to better behavior, schools should try to change students' personalities to make them more ethical.

Conclusion: Business schools can improve the ethics of their students by fostering a desire for social acceptance and suppressing the urge to take risks.

Reasoning: There is a correlation between certain personality traits (risk-taking and social desire) and the number of ethical principles a person holds, which in turn correlates with ethical behavior.

Analysis: This argument makes a massive leap from correlation to causation. Just because risk-takers happen to have fewer principles doesn't mean that 'discouraging' risk-taking will automatically cause someone to adopt more principles. Furthermore, it assumes that these deep-seated personality traits can even be changed by a business school curriculum. Look for an answer that identifies this confusion between a trait being associated with a behavior and the ability to change that behavior by manipulating the trait.
