In this conversation, Judea Pearl, the godfather of modern causal inference, dives into the complexities of causal reasoning and artificial intelligence. He discusses the influence of human biases on AI's decision-making and the potential future of large language models in scientific experimentation. Pearl emphasizes the importance of bridging causal reasoning with statistical education, using malaria as a case study. He also shares insights on the challenges of implementing evidence-based frameworks in education, advocating for a unified understanding of causality across disciplines.
Judea Pearl emphasizes the importance of accurately formulating causal relationships to avoid misleading conclusions, as shown in historical examples like smallpox vaccination.
The discussion on AI highlights the need for integrating causal reasoning to improve machine learning models, distinguishing human thought processes from computational approaches.

The Growth of the Podcast and Gratitude
The podcast has experienced significant growth over its first season, with 23 episodes recorded in 13 different locations worldwide. It has garnered over 30,000 views and 1,300 subscribers on YouTube, alongside reaching 1,300 monthly downloads on various podcast platforms. This journey is celebrated by the host, who expresses heartfelt gratitude to the listeners for their support throughout the past ten months. The success highlights the engaging nature of the content and the connection formed with the audience.
Lessons from Historical Contexts
The conversation touches upon historical lessons regarding causality, illustrated through an anecdote about smallpox vaccinations in 1840s France. Despite initial misconceptions leading people to protest vaccination due to observed deaths, it was demonstrated that the vaccination was effective in reducing deaths from smallpox. This highlights the importance of applying logic correctly to avoid falling into misleading conclusions derived from data. It underlines the need for proper formulation of causal relationships to clear up the confusion surrounding cause and effect.
Causality and Artificial Intelligence
The discussion delves into the role of causality in artificial intelligence and the reasoning capabilities that differentiate human thought processes from machine learning models. While humans often employ shortcuts when making decisions, which can lead to biases, AI systems may have the computational power to delve deeper without these limitations. There's an exploration of how artificial intelligence can potentially utilize causal reasoning similar to humans, especially when models are constructed to represent human-like knowledge. Understanding these differences is crucial for enhancing AI's reasoning abilities.
Research Directions and Causal Discovery Challenges
The podcast highlights the ongoing debate in causal research regarding the limitations of observational data versus experimental data, especially in the context of large language models. It emphasizes that simply having extensive data is insufficient for establishing causality; the nature and structure of the data are critical. The conversation encourages researchers to focus on personalized medicine and decision-making frameworks that can leverage causal insights for practical applications. However, it also acknowledges existing barriers such as educational gaps and the need for greater communication among various disciplines within the causal community.
His work has pretty literally changed the course of my life and I am honored and incredibly grateful we could meet for this great conversation in his home in Los Angeles
To anybody who knows something about modern causal inference, he needs no introduction.
He loves history, philosophy and music, and I believe it's fair to say that he's the godfather of modern causality.
Ladies & gentlemen, please welcome, professor Judea Pearl.
About The Guest Judea Pearl is a computer scientist, and a creator of the Structural Causal Model (SCM) framework for causal inference. In 2011, he has been awarded the Turing Award, the highest distinction in computer science, for his pioneering works on Bayesian networks and graphical causal models and "fundamental contributions to artificial intelligence through the development of a calculus for probabilistic and causal reasoning".
