Sometimes, doing the right thing is just way too hard. So you have use the best approximate substitute available. When you can’t fly like a bird, you can aspire to be a frog that can jump really high, or a flying squirrel.
Decision-making is like that. There is, in my opinion, a “right way” to do decision-making in complex, dynamic environments (VUCA conditions — Volatility, Uncertainty, Complexity, Ambiguity), but most of the time, the right way is way too hard. So like most people, I use approximations tailored to current conditions (I am partial to the geeky joke that life isn’t just hard, it’s NP-hard).
To explain the right way and the approximate way, it helps to think in terms of high-speed maneuvering as a metaphor. Think of the dog-fighting in-an-asteroid-field scene in Star Wars. There are unpredictable moving obstacles and adversaries in the environment, and potential/kinetic energy considerations arising from the physics and energy levels of your own vehicle.
The “right” way to engage such a domain is with high situation awareness and calm mindfulness. Such a mental state allows you to maneuver smoothly and efficiently, with surgically precise moves that minimize entropy generation while achieving your objectives. This is the peak-flow-state, with your OODA-loop humming away at Enlightenment Level 42.
Unfortunately, if you’re like me, you’re in that state perhaps 1% of the time. What do you do at other times?
