Editorial Policy

LifeByLogic is an independent editorial publication of interactive decision tools across cognitive science, behavioral psychology, and life-direction. Every tool on the site begins with the same question: what does the peer-reviewed literature actually say, and how can we surface it in a way a person can use?

We do not invent measurements. We implement validated instruments published in peer-reviewed journals — PNAS, Nature Mental Health, Sleep, JAMA, and others — with full transparency on methodology and citations. When a tool's output is an interpretation rather than a direct measurement, we say so explicitly.

Every claim, framework, or numerical benchmark on a tool page must be traceable to a peer-reviewed academic source, an established government dataset, or a methodology paper from a recognized research institution. We prefer primary sources and link to the underlying research wherever possible.

We do not cite blog posts, popular-press articles, or non-peer-reviewed claims as the foundation of a tool's methodology. Where peer-reviewed data is unavailable, we either decline to build the tool or label the methodology as exploratory.

Citations appear on each tool's methodology page (or methodology section, for single-page tools), with full bibliographic information and DOIs where available.

LifeByLogic has no outside investors. The publication does not sell user data, does not run ad-targeting pixels, and does not accept payment from any party that could influence what tools we build, how we frame their methodology, or what conclusions we report.

The publication is sustained by a mix of: (1) modest affiliate relationships with privacy-respecting services that have been independently evaluated by the editor; (2) optional premium reports purchased by readers; and (3) occasional sponsorship from research-aligned institutions where the sponsorship does not influence editorial content.

Where any of these revenue sources touch a piece of content, the relationship is disclosed inline. Sponsored content is always clearly labeled.

Every tool on LifeByLogic is developed by Abiot Y. Derbie, PhD — a cognitive neuroscientist whose academic background spans psychology (BSc and MSc) and cognitive neuroscience (PhD, The Hong Kong Polytechnic University), with research experience in neuroimaging and predictive modeling of brain–behavior relationships.

The analytical modeling and results-analysis logic of every tool is independently reviewed by Eskezeia Y. Dessie, PhD, Research Fellow at Indiana University School of Medicine, who specializes in computational modeling, predictive analytics, and model validation. The reviewer validates that tool outputs faithfully implement the cited peer-reviewed methodology, tests edge cases, and confirms that results match the underlying mathematics.

Author and reviewer credentials are disclosed on the About page and surfaced in machine-readable form via Schema.org structured data on every page.

Every interactive tool on LifeByLogic publishes its complete methodology: the items measured, the scoring procedure, the reference data used for benchmarking, the limitations, and the citations to the underlying research.

We explicitly disclose what each tool does not measure and where its conclusions are most uncertain. We name the cohort populations the underlying research was conducted on, so users can judge how well the methodology applies to their own situation.

Tools are versioned. Significant methodology updates change the tool version and are logged.

LifeByLogic is not a clinical service, not a medical practice, not a financial advisor, and not a legal advisor. The tools are educational decision support, not professional advice.

Tools that touch health, mental health, or wellbeing surface signals from validated research instruments — they do not diagnose conditions, prescribe treatment, or substitute for evaluation by a licensed professional. Tools that touch life-direction (career, relationships, finances) model patterns — they do not prescribe choices or replace counsel from someone who knows your specific situation.

Where a topic falls outside our editorial competence, we either decline to build the tool, explicitly label it as outside our scope, or refer readers to a more appropriate resource.

Methodology corrections, source clarifications, factual disputes, and editorial concerns are all welcome and can be sent to hello@lifebylogic.com. We read every message and respond, typically within a week. Material errors are corrected per our Corrections Policy.
