Behavior Gap Radio

In this episode of Behavior Gap Radio, Carl tackles the hype and fear swirling around the “Magnificent Seven” stocks and the temptation to either go all-in or get out entirely. He explains why a disciplined investor doesn’t chase hot names—or panic when a single stock grows to 7.5 percent of the S&P 500. Instead, they rebalance based on allocation, not predictions. If something grows beyond its intended weight, you trim it—not because you’re smart enough to call the top, but because it’s out of balance relative to your goals and values. A clear, grounded take on investing like an adult.

In this episode of Behavior Gap Radio, Carl revisits one of the most striking examples of the behavior gap: Peter Lynch’s legendary Magellan Fund. While the fund returned an extraordinary 29 percent, the average investor captured only a fraction of it—and some studies say many even lost money. Why? Because humans buy high, sell low, and chase what’s hot. Carl breaks down how this pattern shows up again and again, why even great investment processes fail if behavior doesn’t support them, and why the real challenge isn’t finding the best fund… it’s staying in it.

In this episode of Behavior Gap Radio, Carl returns to his roots and digs into the heart of investing: having a clear, defensible process. Whether you’re an advisor, a planner, or simply someone who invests, he challenges you to ask one simple question: Why are you invested the way you’re invested? Carl explains why relying on headlines, hype, or a single podcast won’t cut it—and why writing down your investment process, as if you had to defend it in a room full of smart people, might be the most important exercise you do before the next real test arrives.

In this short episode of Behavior Gap Radio, Carl reflects on how easy it is to drift into tracking the wrong metrics—the ones the world cares about, not the ones that actually matter to you. When your attention slips to measures that don’t align with your values, things get messy. The antidote is simple but essential: get clear on what matters, then measure only that.

In this episode of Behavior Gap Radio, Carl explores what he calls the discipline of more—or what he sometimes calls the bigger yes. Instead of fighting bad habits through willpower, he suggests crowding them out by filling life with things you love. From moving woodchips under a headlamp to swapping screen time for saunas and books, Carl shares how choosing a “bigger yes” creates space for what matters—and quietly leaves no room for what doesn’t.

In this episode of Behavior Gap Radio, Carl introduces a phrase he’s been searching for: ecological naïveté—the idea that our instincts were perfectly suited for a world that no longer exists. Using examples from nature and investing, he explains why our ancient wiring makes us want to run from market drops and chase safety, even when we know better. The takeaway? You’re not a bad investor—you’re just human. The work isn’t to fight those instincts, but to notice them with compassion and patience.

Carl reflects on how the scariest terrain to navigate isn’t out there—it’s in your own heart.
