After a short break Sweetspot Safari returns with guest explorer Rob Bell. Rob is a talented broadcaster, podcaster and engineer and we explore a broad range of topics centering on the theme of ignorance vs knowledge. We talk about how the internet might be emphasising superficial knowledge at the expense of deeper understanding, the difference between general and specialist knowledge, the wisdom beneath the concept of beginner's mind, the fascinating Dunning-Kruger effect and much more. As usual the theme of critical thinking weaves through this conversation and we finish up by pondering whether more knowledge equates to more happiness.
