Abstrakt: Framed by a patterns of history of robust statistics advantages and disadvantages of the robust processing data are explained and
put in the proper context. The discussions are illustrated by series of tables demonstrating the real state of situation,
not repeating the statistical folklore e.\,g. about the loss of efficiency of the robust estimators. Examples of
accompanying diagnostic tools and modifications of the ``parent'' method of the {\it least wighted squares} for the
various situations, e.\,g. of broken orthogonality condition, are also presented.
