Third conversation between Nassim Nicholas Taleb & Yaneer Bar-Yam about uncertainty, certainty and what to do when there is a systemic risk; what not to do when a truck is headed your way. How acting early would have cost less? They also discuss:

  • Why we should make decisions without reliable data & use precautionary principles
  • How the costs would be so much smaller if we would have acted earlier.
