Are you ready to discover why building customer self-confidence is more crucial than ever in today's B2B sales landscape? Brent Adamson and Karl Schmidt join us today, the duo behind the upcoming book "The Framemaking Sale." These sales experts unravel the critical yet often overlooked aspect of buyer confidence. They shift the focus from traditional supplier-centric models to the empowering idea that true confidence comes from within the customers themselves. This perspective not only transforms how we view B2B sales, but also highlights the importance of nurturing decision confidence. Throughout our conversation, Brent and Karl introduce their innovative concept of framemaking, a strategy that aligns sales solutions with client priorities. This approach goes beyond typical sales tactics by fostering genuine, lasting relationships with clients, even when they choose competitors. Their ideas promise to shake up conventional sales methods. Topics covered during this episode include: Why buyer confidence should be supplier-agnostic and focus on customers' decision making abilities. How Brent and Karl met each other at Corporate Executive Board (now part of Gartner). Why nurturing customer decision confidence is crucial in B2B. How framemaking aligns sales solutions with client priorities to overcome decision complexity. Why the book emphasizes customer confidence over supplier trust for effective decision making. The impact of decision complexity, information overload, and outcome uncertainty. Why understanding clients' businesses deeply helps navigate obstacles and maintain deal momentum. How salespeople can anticipate and overcome potential deal barriers. Why gaining customer confidence involves addressing emotional and rational decision aspects. Listen now to learn how to revolutionize your B2B sales approach with innovative framemaking techniques that build lasting customer relationships.

The Illusion of Thinking: Do AI Models Really Reason? 13:40

9 days ago13:40

13:40

It looks incredibly impressive when a large language model explains its step-by-step thought process, giving us a window into its "mind." But what if that visible reasoning is a sophisticated illusion? This episode dives deep into a groundbreaking study on the new generation of "Large Reasoning Models" (LRMs)—AIs specifically designed to show their work. We explore the surprising and counterintuitive findings that challenge our assumptions about machine intelligence. Discover the three distinct performance regimes where these models can "overthink" simple problems, shine on moderately complex tasks, and then experience a complete "performance collapse" when things get too hard. We'll discuss the most shocking discoveries: why models paradoxically reduce their effort when problems get harder, and why their performance doesn't improve even when they're given the exact algorithm to solve a puzzle. Is AI's reasoning ability just advanced pattern matching, or are we on the path to true artificial thought? Reference: This discussion is based on the findings from the Apple Machine Learning Research paper, "The Illusion of Thinking: Understanding the Strengths and Limitations of Large Language Models with Pyramids of Thought." https://machinelearning.apple.com/research/illusion-of-thinking…

It sounds like science fiction, but researchers are grappling with the very real challenge of ensuring Artificial General Intelligence (AGI) is safe for humanity. Join us for a deep dive into the cutting edge of AI safety research, unpacking the technical hurdles and potential solutions. We explore the core risks – from intentional misalignment and misuse to unintentional mistakes – and the crucial assumptions guiding current research, like the pace of AI progress and the "approximate continuity" of its development. Learn about the key strategies being developed, including safer design patterns, robust control measures, and the concept of "informed oversight," as we navigate the complex balance between harnessing AGI's immense potential benefits and mitigating its profound risks.

This episode is your fast track through the fundamentals of machine learning, breaking down complex concepts into understandable nuggets. Drawing inspiration from Stanford course materials, we ditch the dense textbook approach and offer a clear, conversational deep dive into the core mechanics of AI learning. Join us as we explore: Linear Predictors: The versatile workhorses of early ML, from classifying spam to predicting prices. Feature Extraction: The art of turning raw data (like an email) into numbers the algorithm can understand. Weights & Scores: How AI weighs different information (like ingredients in a recipe) to make a prediction using the dot product. Loss Minimization & Margin: How do we measure when AI gets it wrong, and how does it use that feedback (like the concept of 'margin') to improve? Optimization Powerhouses: Unpacking Gradient Descent and its faster cousin, Stochastic Gradient Descent (SGD) – the engines that drive the learning process. Whether you're curious about AI or need a refresher on the basics, this episode provides a solid foundation, explaining how machines learn without needing an advanced degree.
