About the site

Connections & disclosures

The site presents Jason Hreha’s perspective on behavioral science. Here are the books, products, and methods connected to that work.

Jason’s writing and methods

The Behavioral Scientist brings together educational references, guides, and Jason’s essays. His Substack contains additional writing. BehavioralStrategy.com describes his method for choosing suitable behaviors before designing ways to encourage them. The site distinguishes that practical framework from the research used to examine particular claims.

Books and products

Real Change is Jason’s book. Its companion worksheets are available here without a purchase. Twofold is the personality-assessment product he is building. You can use the learning path and worksheets without taking a test or buying a report.

Evidence and judgment

An explanation of a concept, a summary of a book, and an evidence assessment serve different purposes. A summary does not endorse every claim in its source. Where a practical recommendation goes beyond a study’s findings, that step should be clear. A publication date does not tell you when all of a page’s scientific claims were last checked.

Questions or corrections

If a connection is unclear or you find a claim that needs correction, send the page and the relevant details.
