"Isn't That Just Crutches?"

The honest answer is it depends, and the research is clear about how. Yes, if you offload a specific phone number, you'll remember that number less well. But the "weakening" is item-specific (that one fact), not a global decline in your thinking. And here's the part that flips it: offloading one load frees capacity for the next thing, in studies, saving one set of information actually improved people's memory for what they learned afterward. So externalizing doesn't drain you; it redeploys you. The clean rule: use a prosthesis where capacity is the real bottleneck (the stuff you'll always need help holding, appointments, bills, steps), and use it as a scaffold you can fade where you're genuinely trying to build a skill. A wheelchair isn't a moral failing for someone who can't walk the distance; neither is a reminder for a brain that doesn't hold time. You're not getting weaker. You're getting equipped.
