This overview emphasizes the importance of "maziness" and "window" as frameworks for discussing reliability and unbiasedness in time-dependent research. It addresses critical aspects like study design, measurement quality, intervention strategies, and sampling validity, which are central to ensuring high-quality research. The piece questions the adequacy of "content reliability" as a supervisory criterion for quality studies and stresses the necessity of peer review focused on study design quality prior to data collection, underscoring that evaluation must occur before results are published.

'Maziness' and 'window' are useful concepts to illustrate (to our clients) the notions of reliability and unbiasedness when time-dependency is subject of study. • Study design, measurement quality, intervention strategy and validity of sampling procedures are the recurrent key issues in every study, data-analysis comes later on. • Is ‘content reliability’ a strong enough concept to serve as a supervising criterion in strategies that warrant studies of high quality? Is it evaluable? Quantifiable? Unprejudiced? • The peer review should assess the design quality of the study as laid down in the study protocol before the study sets off, not afterwards if the results are offered for publication. It's too late then.
