Ahat [919]

North Americans seem to be much more likely to have internal locus of control than people from Middle Eastern countries.

<u>Explanation: </u>

An individual with an internal locus of control often holds his own self responsible for the results that he gets out of the works done by him. Alternatively, an individual with external locus of control believes that the results of his work are controlled by external factors.

North Americans are much more materialistic and unorthodox than the people of the Middle East. It is their habit to take more response on both their successes and failures. Whereas, the people from the middle east rest their faith on external factors like luck and God as much as on their efforts.
