Scientific journals

Data published in scientific journals are generally taken from recent studies conducted by the authors. The random samples are not always representative, since studies are often able to consider only sub-populations relevant to the issues that they address. Likewise, the dimensions studied anthropometrically are generally selected purely with respect to the scientific problem at hand. This is the case not only for ergonomic studies, but also for many biological and medical studies, for example into the causes of obesity. Collections of data that are representative and important above all for designers and similar users rarely appear in scientific publications.
