Code review and personality: is performance linked to MBTI type?

Dependability frequently focuses on approaches such as rigorous design and fault tolerance. A final software product is strongly influenced by the people who created it. Large variations in individual performance in software development have been observed. Some form of innate programming ability might account for some of the differences. The influence of personality on computer programming has been examined but typically treated programming as a single process. As Weinberg [1] suggested, different aspects of software development require different abilities so there may be no one personality type which is better overall. To examine this, a study was carried out to discover if there was a particular personality type which tended to perform better at one specific task, in this case code review. It was found that people with a specific personality type performed significantly better on the task.
