Psychologist: We asked 100 entrepreneurs and 100 business managers to answer various questions and rate how confident they were that their responses were correct.
Evidence
We asked 100 entrepreneurs and 100 business managers to answer various questions and rate how confident they were that their responses were correct.
While members of each group were overconfident, in general the entrepreneurs were much more so than the business managers.
Conclusion
This indicates that people who are especially overconfident are more likely to attempt to start a business in spite of the enormous odds against success than people who are less confident.
Evaluate
Notice the shift in subject between the evidence and the conclusion. The evidence compares the average amount of overconfidence of two groups, while the conclusion is about people who are especially overconfident. To strengthen the conclusion, the correct answer should discuss people who are especially overconfident.
