[Impact factors and bibliometrics of science. Does pure science really exist?]

The impact factor is an artificially created indicator which when applied separately does not achieve the value attributed to it. In its assessment a number of different influences are projected which cause partial mistakes with a cumulative effect. It can have an even worse effect if the impact factor is incorrectly conceived or inadequately handled. Only in a long-term review using specific corrections it can serve to determine really top class periodicals but only within the framework of a single scientific discipline. It is not suitable for comparison of interdisciplinary journals. It should be used very carefully in the evaluation of authors. However it is still used in various types of administrative management. From the submitted paper it may seen that with a certain amount of overstatement it is personified and acts on its own. Its personification is homo sapiens scientometricus who evaluates himself as well as his environment which is represented by mere homo sapiens scientificus. In addition to the impact factor the authors discuss also other indicators and some aspects of scientometry.
