Synopsis · Executive Overview

Information Theory, Cybernetics & Rhetoric investigates claude Shannon's mathematical theory of communication, channel capacity and entropy, Norbert Wiener's cybernetics and feedback loops, and classical and modern rhetoric.

Section I · Primary Literature & Evidence Synthesis

What the Peer-Reviewed Record Establishes

The primary research record in Information Theory, Cybernetics & Rhetoric is stratified by study design so that meta-analyses and replicated randomised controlled trials (T1–T2) carry greater epistemic weight than observational cohorts (T3–T4) or preclinical laboratory work (T5). Leading graded findings establish the core empirical baseline: [T6] The method of dispersion correction as an add-on to standard Kohn-Sham density functional theory (DFT-D) has been refined regarding higher accuracy, broader range of applicability, and less empiricism. [12] [T6] BackgroundModern medicine often clashes with traditional medicine such as Chinese herbal medicine because of the little understanding of the underlying mechanisms of action of the herbs. [9]

Further clinical and mechanistic stratification across the literature demonstrates: [T6] ObjectivesPatient-reported outcomes (PROs) are essential when evaluating many new treatments in health care; yet, current measures have been limited by a lack of precision, standardization, and comparability of scores across studies and diseases. [13] [T6] A free-energy principle has been proposed recently that accounts for action, perception and learning. [14]

Comparative Evaluation of Levers & Theoretical Models

Section III · Historical Trajectory & Contested Frontiers

Evolution of the Field, Open Debates & Active Trials

Chronologically, the field evolved through key inflection points: in 1988, Measuring the accuracy of diagnostic systems. (Diagnostic systems of several kinds are used to distinguish between two classes of events, essentially "signals" and "noise"); in 2010, A consistent and accurate ab initio parametrization of density functional dispersion correction (DFT-D) for … (The method of dispersion correction as an add-on to standard Kohn-Sham density functional theory (DFT-D) has been refined regarding higher accuracy, broader range of applicability, and less empiricism); in 2010, The free-energy principle: a unified brain theory? (A free-energy principle has been proposed recently that accounts for action, perception and learning); in 2020, From What to How: An Initial Review of Publicly Available AI Ethics Tools, Methods and Research to Translate… (The debate about the ethical implications of Artificial Intelligence dates from the 1960s (Samuel in Science, 132(3429):741-742, 1960).

Section IV · Evidentiary Gaps & Research Frontiers
