"The accomplishment ratio : A treatment of the inherited determinants of…." by Raymond Franzen is a scientific publication written in the early 20th century. It examines disparities in school achievement through standardized testing and statistical analysis, proposing the “Accomplishment Ratio” to judge how well students’ actual progress aligns with their intellectual potential. The study focuses on how classification, measurement, and targeted instruction can raise achievement to match measured intelligence, probing whether differences in school performance are inherited or shaped by schooling. The opening of the work lays out the rationale for replacing opinion with standardized measurement in schools and defines a toolkit of indices: Intelligence Quotient (IQ), Subject Quotients (SQ), Subject Ratios (SR), and their average, the Accomplishment Ratio (AccR). It explains how age norms are derived via regressions of score on age (with corrections for truncation) and then details the Garden City experiment: 200 pupils were tested with Binet, Thorndike reading and vocabulary, Woody-McCall arithmetic, and Kelley-Trabue language; students were reclassified by subject ability using “relation sheets,” regrouped for instruction, and “pushed” until their SQs approached their IQs. The procedures include precise scoring-to-age conversions, ongoing regrading by subject, and using AccR as a fairer, intelligence-referenced school mark for teachers and parents. Early statistical results show that, under special treatment, subject quotients move toward IQ and correlations strengthen across grades, suggesting intelligence is the primary driver of achievement while remaining disparities likely reflect schooling mismatches rather than distinct inherited special abilities.

"A szociológia módszere" by Émile Durkheim is a scientific publication written in the late 19th century. The work delves into the methodology of sociology, particularly focusing on the concept of social facts and their objective study. Durkheim asserts that social phenomena influence individuals, exerting a form of external constraint that shapes human actions and behaviors. This foundational perspective sets the stage for a broader exploration of social structures and institutions within the field of sociology. The opening of the text establishes Durkheim's intent to define and analyze social facts, which he describes as ways of acting, thinking, and feeling that exist outside of the individual and exert coercive force within society. He discusses the importance of viewing these social phenomena as 'things' that can be studied scientifically, in the same manner as natural phenomena. By emphasizing this objective approach in sociological research, Durkheim seeks to differentiate sociology from psychology and biology, arguing that it occupies a unique place focused on collective social structures rather than individual behaviors alone. The introduction sets a framework for understanding how societal norms and practices shape human experience and opens up discussions regarding the systematic investigation of social dynamics.
