Yeah a direct inversion doesn't seem to work. I think you invert the idea but with the premise that you don't want to do it.
So instead of: How do I decrease adoption?
You think: How do I avoid decreasing adoption?
I think this works anyway. Another example:
Goal: Fly to Spain
Question: How do I fly to Spain?
The inverted question should not be "How do I not fly to Spain?" (answer: get put on a flying ban or don't buy a ticket) but "How do I avoid not flying to Spain?" (answer: pick a date and book tickets)
But that isn't really an inversion, more a double negative.
The example given is "how do I keep my pilots alive?" with the inversion "what could kill my pilots?". Your result would be "how do I avoid not keeping my pilots alive?", which is just the original question.
I have read about mathematician Abraham Wald's operational research for the US on WWII aircraft armor placement. Wald challenged the instincts and conventional wisdom of military commanders who thought that more armor should be added to the places on airplanes that had the most bullet holes upon returning from a mission.
Wald instead flipped it and recommended armor be added to the areas with less or no combat damage on returning airplanes because the shot-up areas were the parts of the plane that COULD withstand damage, since the plane had made it back.
> The example given is "how do I keep my pilots alive?" with the inversion "what could kill my pilots?".
Pretty much that, except in any long-standing industry, it's framed as "what does kill pilots?" and "Lets study the last few decades of pilot mortality data and identify causes". Safety standard improve one Air-crash Investigation at a time.
"The Field Guide to Understanding 'Human Error'" by Sidney Dekker is probably where to start with that field.
I imagine a single negation would increase the solution space so much that it wouldn't be useful anymore. A double negation will change the question format, so our (irrational) minds treat it differently, yet keep the solution space the same.
It might be irrational in some cases, but it also might have to do with the double negation of a statement not being practically equivalent to the statement, as in constructive mathematics.
In what situations do the answers to the inverse differ from the original? It seems to me it's just a rewording of the original question with a double negative.
Good point - the 'fly to Spain' example wasn't the best. Running through multiple things in my head.. it seems the most powerful thing is to have a good initial question so the inversion actually helps.
