The results of Reynierse's work are shown below:

This table displays the average personality type indicated from surveys of the three different levels of management in American and Japanese companies. Individuals within any group could be significantly different from the average.
There are three different personality types dominate in management in both cultures:

• ESTJ: Fact minded organizer. Practical, realistic, matter of fact. Not interested in subjects they see no use for. Like to run and organize activities. Good administrators but likely to ignore the feelings of people. Interested in details.
  
• ENTJ: Intuitive, innovative organizer. Logical, decisive leaders. Good in anything that requires reasoning and intelligent talk. Can be overconfident. More interested in getting the job done than in people's feelings. Interested in the "big picture."
  
• ESFP: Realistic adapter in human relationships. Oriented to practical, first hand experience. Friendly and highly observant of needs and feelings of people. Remembers facts better than theories.
  

SJ: Sensing judgers are motivated by duty and responsibility
NT: Intuitive thinkers are motivated by power and knowledge
SP: Sensing perceivers are motivated by freedom and action
NF: Intuitive feelers are motivated by spirit and unity (not a dominant temperament in these populations)
