Simplifying Complexity
Do you have free will? - Part 2
Feb 17, 2025
In this engaging discussion, Kevin Mitchell, an Associate Professor of Genetics and Neuroscience at Trinity College Dublin, dives into the fascinating realm of metacognition—how we think about our thinking. He contrasts human decision-making with that of other species, exploring how our evolved brain structure influences belief evaluation and planning. The conversation delves into the complexities surrounding free will versus determinism, revealing the intertwined nature of genetics, consciousness, and our understanding of moral responsibility.

Evolution of Cognitive Complexity
Multicellular life forms have evolved to exhibit varying levels of cognitive complexity, largely influenced by their ecological niches and life strategies. While vertebrates possess advanced cognitive functions, other successful organisms like plants and invertebrates have thrived through different adaptations, such as gathering energy through photosynthesis or direct chemical sensing. Over evolutionary time, brain size in mammals, especially primates and humans, has increased, leading to enhanced cognitive abilities. This increased complexity has allowed organisms to explore new environments and develop more sophisticated decision-making processes, establishing a feedback loop between brain development and environmental adaptation.
