This also is mistaken: the article addresses randomness, expected or otherwise, in the sections on the error distribution, statistical independence, Benford's law, rounding, and the systematic properties expressed by the equation for longevity.
Another important restriction which is imposed by the previous models is the statistical independence assumption.

30) If the observed frequencies (survey results) differ significantly (< 0,5 per cent level of significance) from the expected frequencies, then the assumption of statistical independence is contradicted, and at least some relationship between the two variables is implied.
Utilizing groups themselves as the unit of analysis, rather than the individual scores, decreases the possibility of the statistical independence assumption being violated and systematic error being created (McMillan, 1999).
In addition, the faithfulness condition rules out those models in which statistical independence relations follow was a result of special coincidences among the parameter values.
