What are some of the reasons that traits like conscientiousness or core self-evaluations, as measured by personality tests are likely to relate to job performance across many occupations?
1. A study which investigated the 'Big Five' dimensions to various job performance criteria and occupations shows that conscientiousness showed consistent relations with all job performance criteria for all occupational groups. Extraversion was a valid predictor for two occupations involving social interaction, managers and sales (across criterion types) (barrack et al, (1991).
Dr John M. Oldham lists the following eight characteristic traits and behaviors of the Conscientious Personality style as listed in his The New Personality Self Portrait( Oldham et al, 1995):
1. Hard Work
2. Doing the right thing

6. Order and detail

There are no studies that indicate the importance of extraversion in other kind of jobs. This could be because extraverts are good at interpersonal communication and but there is nothing else in that trait that could ensure success in jobs or aspects of jobs that does not involve people interaction.
