The U.S. Air Force is the world's largest and most technologically advanced air force. It comprises hundreds of thousands of members, all with different personalities that need to work together to ensure our national security. This study uses a modified Myers-Briggs Type Indicator and line bisection test to determine the personality types and hemisphericity of a small group of these military members working on the global war on terror. Officers and enlisted members are looked at individually and collectively, assessments are made on the group as a whole, and comparisons are made between enlisted members and officers. The findings suggest that there are many similarities between officers and enlisted personnel. They both prefer introversion, sensing, thinking, and judging; they are also predominantly left-brained individuals. Some similarities include officers and enlisted members preferring to work quietly while still exhibiting a realistic problem-solving style. They were different in their judging and perceiving traits; officers were found to be more judgmental. Various statistical tests were performed; the traits of officers and enlisted personnel were significantly similar, with a confidence level as low as 50%. © 2010 ASCE.
