How we research, write, fact-check, and update content on this site.
Neuroscience claims on this site link to peer-reviewed studies indexed on PubMed (U.S. National Library of Medicine). We prefer primary research over secondary commentary, recent over older studies for emerging fields, and replicated findings over single studies.
All content involving neuroscience claims is reviewed by Dr. Sarah Whitfield, PhD, a Cognitive Neuroscientist and Brainwave Research Specialist. Product evaluation content (user reviews, pricing, comparison) is researched against multiple independent sources and verified user-reviewed reports.
We cite PubMed IDs (PMIDs) for neuroscience claims, link to original sources, and avoid relying on press releases or marketing materials as primary sources.
This site earns affiliate commission when readers purchase The Brain Song through our links. This relationship is disclosed throughout the site. Affiliate revenue does not change our evaluation. We have published critical user reviews and identified real product limitations.
Editorial staff and reviewers do not receive direct compensation from the creator or company behind The Brain Song. Our only financial relationship is through standard ClickBank affiliate commissions on referred purchases.
Pricing and pricing-adjacent content is reviewed quarterly. Neuroscience content is reviewed annually or when significant new research emerges. The current version of this site was last comprehensively reviewed on May 12, 2026.
If we publish an error, we correct it publicly. Email editorial@brainsongthe.com with corrections; we will respond within 2 business days and publish corrections within 5 business days where warranted.
