Add a sensor

Make a consequential stock, flow, or outcome visible that the decision-maker currently cannot see.

You "sleep badly" but could not say how badly, or when, or what makes it worse. Wine some nights, late workouts others, stressful days: everything blurs together. You are adjusting bedtime, caffeine, and exercise while effectively blindfolded, steering a variable you have never once actually measured.

Add a sensor makes a consequential stock, flow, or outcome visible that the decision-maker currently cannot see. The cue: you keep making decisions that depend on a quantity you never observe, so every adjustment is a guess. Steps: name the invisible quantity your choices hinge on (actual sleep duration and timing, not felt grogginess); install the cheapest adequate instrument, a tracker or even a paper log of lights-out and wake time; then route the reading to the moment of decision, glancing at the week's log before deciding on that third coffee. What changes: patterns pop out within two weeks, wine nights cost you 40 minutes, late workouts cost nothing, and your adjustments start landing on real causes. Don't add sensors to everything, though; measurement has attention costs, and tracking a harmless variable can breed anxiety and fiddling. Sense what you will act on, nothing more.
