**The scariest part of the Known/Unknown Matrix** Unknown unknowns are what you should be afraid of. When you're taking on a task, project, or new responsibility - the unknown unknowns are what have the biggest chance of wrecking your chances of success (or even, your life). When it comes to overspending, taking too long, or producing a shoddy product - the culprit can be the result of [[Known Unknowns]]. But when you quintuple your budget, take years instead of months, or aim to produce a result that's impossible - it's almost always because of an unknown unknown. > [!tldr] ⚠️ Known Unknowns might cause overruns by several dozen percent, but unknown unknowns can cause overruns by several orders of magnitude. **** # More ## Source ## Related - [[Known Unknown Matrix]]
