There is no specialty assumed, only interest and a certain level of intelligence. They are generally published by commercial enterprises or individuals, although some emanate from specific professional organizations. The main purpose of periodicals in this category is to provide information, in a general manner, to a broad audience of concerned citizens. These publications rarely, if ever, cite sources. Information published in such journals is often second or third hand and the original source is sometimes obscure.
Authors are generally magazine staff members of free lance writers.
Articles are usually very short, written in simple language and are designed to meet a minimal education level. There is generally little depth to the content of these articles. Their language is elementary and occasionally inflammatory or sensational. They assume a certain gullibility in their audience. The main purpose of sensational magazines seems to be to arouse curiosity and to cater to popular superstitions.
