Is Your Brain Too Out of Shape to Make Your Biggest Decision? Cognitive Outsourcing & Retirement

What if the biggest threat to your retirement isn’t your portfolio but the fact that your brain has quietly stopped doing its own thinking? In this episode, Rachael Van Pelt, PhD unpacks cognitive outsourcing: the growing habit of letting devices, apps, and AI handle the mental tasks that keep your brain sharp. Drawing on landmark research, Rachael reveals how the Google Effect is restructuring your memory, how internet and AI searches inflate your illusion of knowledge, and how habitual GPS use is literally shrinking the part of your brain most vulnerable to Alzheimer’s. She shares the story of Diane and Mark, a couple who had every spreadsheet and calculator output they needed and still couldn’t pull the trigger. The missing piece wasn’t more data. It was practiced self-trust. Rachael introduces a Cognitive Fitness Framework (outsource your inputs, but never outsource your judgment) and explains why the difficulty of doing your own thinking is the point. 👉 Try her free virtual coaching tool Rightsizing Decision Coach at coach.rightsizeretirement.com to find out where your home is quietly working against your body, brain, bank, or base.   Chapters 00:00 The Pop Quiz: Three Questions That Reveal How Much Thinking You’ve Outsourced 01:41 What Is Cognitive Outsourcing — And Why It’s Not the Same as Doom-Scrolling 03:20 The Science: Google Effect, Illusion of Knowledge & GPS-Driven Brain Atrophy 07:46 Why Cognitive Outsourcing Gets More Dangerous in Your Go-Strong Years 10:10 Case Study: Diane & Mark — All the Data, None of the Confidence 11:43 The Cognitive Fitness Framework: Outsource Inputs, Never Outsource Judgment  ★★★★★★★★★★★★★★★★★★★★★★★★★★★★★   Rightsized Home & Health Review https://calendly.com/rachael-vanpelt/discovery Rachael Van Pelt, PhD is a healthspan scientist, Realtor and coach helping 55+ adults rightsize with confidence.
