Bo Bennett On Building Science Based Learning

## Episode Summary Bo Bennett returns to share how frustration with hype-driven language apps led him to build ScienceBasedLearning.com—a tool he uses himself every single day, eight months running. The conversation digs into the specific cognitive science behind the app, especially spaced repetition: how the system walks a word back down the retention ladder the moment you forget it, then climbs it back up. Bo also gets candid about the one challenge that has nothing to do with the science: he's a proven B2B marketer who now has to figure out direct-to-consumer. ## What You'll Learn - **Why spaced repetition works at the forgetting moment, not just the learning moment:** when you miss a word at the three-day mark, the app drops it back to the one-hour interval rather than discarding or repeating it randomly - **The 90–95% lifetime retention claim:** Bo explains that a word cycled through the full sequence—15 minutes, 1 hour, 1 day, 3 days, 1 week, 1 month—has a 90–95% chance of being remembered for life, versus the far lower baseline of traditional study - **How CEFR levels (A1–C2) are handled through self-reporting**, with users able to raise or lower their level mid-course if content feels too easy or too difficult - **Why AI-generated content avoids repetitiveness where it matters:** definitions stay stable for retention, but articles, stories, and freeform conversations are dynamically generated so no two are alike - **The consumer-vs-creator marketing gap Bo openly admits:** building for authors and businesses is familiar ground; reaching everyday Spanish or Japanese learners on their lunch break is a skill he says he still needs to develop ## Notable Quotes > "The brain doesn't process all information the same way—language learning is a very specific branch of cognitive science, and that's the part I really had to dig into." — Bo Bennett > "If a term goes through the full sequence—15 minutes, an hour, a day, a week, a month—the chances are 90 to 95% that you will remember it for the rest of your life." — Bo Bennett ## About the Guest Bo Bennett, PhD is the founder of Archieboy Holdings and the creator of ScienceBasedLearning.com. He describes himself as a social scientist with a background that crosses into cognitive science, and he built the language-learning app to solve his own problem while studying Spanish. He has been using the tool daily for eight months and is candid about the fact that, unlike his other products aimed at authors and businesses, this one required him to learn a new field—the cognitive science of language acquisition—from scratch. He is also the creator of other Archieboy properties discussed in previous episodes of this show. ## Topics Covered - Spaced Repetition Science - CEFR Level Self-Reporting - AI-Generated Language Content - Consumer vs. B2B Marketing - Professor Mode Feature - Long-Term Vocabulary Retention - Building Tools for Personal Use
