Rationals are the problem solving temperament - while working with a problem, they try to find solutions that have application in the real world and are reasonable, however, they stick to the concept and fundamental principles involved in the situation to solve it. They have a need to accomplish their goals and will work hard to get the job done. If their search for knowledge and competence is blocked, they will eventually become edgy - repressing their feelings in order to relieve the stress. They see the world with an unique perspective and enjoy finding solutions. They know what they are worth and might manipulate people to get what they want. Their greatest strength is strategy.
