African history, plant genetics, and child development are specific areas of knowledge. So too are biology, mathematics, organic chemistry, engineering, and many other such disciplines. In these areas, knowledge developed by many researchers has withstood tests to prove its accuracy. There are established methods to find solutions to problems, and considerable consensus exists as to what is correct and incorrect and what are the appropriate standards for judgment. Experts have read widely about a phenomenon, made many observations over a period of time, and analyzed an issue closely. For these reasons, they are more likely to have knowledge than the average person would. If a claim is to be justified on the grounds that an authority has asserted it, then that person must really be an expert in an established field of knowledge and the claim in question must lie within the field in which he or she is an expert.
