This occupation field involves careers that require the use of analytical skills to solve complex problems. Scientists are independent, abstract thinkers who seek to explain complex phenomenon in a complex world. They have efficient minds, which rely on logical deductive approaches to understanding the natural world. They often have a natural aptitude and interest in science and mathematics. However, whilst some individuals prefer the more practical aspects of working with animals, others prefer the research component, which includes working with formulae and complex mathematical problems. Success in Natural Sciences requires a commitment to study and the acquisition of specialised knowledge in certain fields. Knowledge and the ability to apply that knowledge distinguishes one scientist from another. Good scientists become experts in their respective fields of interest.
