The thing is, when we're faced with something we don't fully understand, it's easy to get intimidated or overwhelmed. But Black Box thinking says, "Hey, it's okay if you don't know all the details - just focus on what you can understand, and work from there." It's like trying to assemble a piece of furniture without reading the instructions - you might not know all the tiny details, but you can still figure it out by looking at the pictures and using your common sense.
For example, think about driving a car. You don't need to be a mechanic to drive one, right? You just need to know how to use the controls - the steering wheel, the pedals, and the gears. You don't need to know all about the engine or the transmission - that's all just "black box" stuff that you can ignore, unless you're really curious about it.
That's kind of what the book Inside The Black Box is all about. Written by Black and William in 1998, it explores the idea of Black Box thinking and how it can be applied to all sorts of areas of life - not just science and engineering, but also things like finance and politics.
