The concept of multiple intelligences emerged after Howard Gardner redefined intelligence. According to Gardner's theory, human beings have different types of intelligence, and depending on their respective types of intelligence, human beings have different skills in different areas. Human beings can succeed and be more productive in areas where they are skilled. Therefore, choosing appropriate professions, based on one's intelligence type, is important for both individuals and society. This study aims to develop a technique to help high school students in the professional selection process using artificial intelligence. The questionnaire was used as a research method and the data was analyzed through Fuzzy Logic Toolbox, which is a sub-unit of the software called MATLAB. It aimed to guide students into a suitable profession and build more successful and productive professions.Keywords; Artificial Intelligence, Multiple Intelligence, Fuzzy Logic, Fuzzy Logic Toolkit, Career Guidance, Decision Making1. IntroductionProfession is an individual title, which is usually acquired after a series of education and a process requiring special knowledge, skills and work to have a more comfortable life. The meaning of the word profession may differ from person to person. For some people, this may only mean money; for someone who deserves respect; for someone to generate something new and realize capabilities, for others it can also mean all of these together. Satisfaction, sense of accomplishment and happiness, which are achieved in professional life, affect a person's daily life. Unlike this condition, dissatisfaction, failure and unhappiness in professional life can lead to certain psychological problems. One of the... middle of paper ......logic is based on uncertainties. In traditional logic, there is no room for uncertainties. Some technological areas in which fuzzy logic is used can be ordered as follows:• Cameras controlled by fuzzy logic (Sanyo – Fisher, Canon, Minolta)• Video cameras (Panasonic)• Washing machines and dishwashers (Matsushita)• Control of Sundai urban subway in Japan (Hitachi)• Braking system in vehicles (Nissan)• Vacuum cleaners (Matsushita)• Elevators (Elevator) (Fujitec-Toshiba, Mitsubishi, Hitachi)• Air conditioners (Matsushita)• Televisions and computers ( Sony)• Cement industry (Mitsubishi Chem.)• Steel industry (Nippon Steel)• Car gearbox systems (Subaru, Nissan)It is also used in many other fields such as toasters, micro ovens -waves, handwriting recognition, helicopter flight control system, etc. (Ural, 2006). The areas of application become more and more numerous over time.
