In this episode, Ben, Cameron, and Dan are joined by Ted Cadsby, former executive at CIBC, author of The Power of Index Funds, Closing the Mind Gap, and Hard to Be Human. Ted brings a rare combination of experience in both finance and cognitive psychology, having helped introduce index investing to Canada before turning his attention to how human thinking itself often misleads us. Ted shares inside stories from his time at CIBC—how he tried to make the bank an indexing leader in the late 1990s, the pushback he faced, and why he still believes so deeply in indexing today. Then, the conversation turns to human cognition: why our brains evolved for simplicity, certainty, and emotion, and how those traits can sabotage both our portfolios and our peace of mind. From "greedy reductionism" and "certainty addiction" to emotional overreaction and competing selves, Ted unpacks the five cognitive design flaws that make it hard to be human—and how metacognition and mindfulness can help us overcome them.
