I saw the statement, âWhich is the essential number?â
Numbers are clues to understanding the world, and collecting a lot of them helps us understand it better. Trying to âpick a sideâ is an act that leads away from understanding.
concrete example
-
The question of which is more essential, the ânumber of infectedâ or the ânumber of severely ill or deadâ in COVID19.
- There is also another âbasic reproduction numberâ and the topic of the basic reproduction number of Delta stock is high around 2
- The overall basic reproduction number continues to rise at about 1.2, and if this is due to âan increasing percentage of delta sharesâ it will rise to about 2 if left alone
- While the number of reproductions exceeds 1, the ânumber of infectedâ increases exponentially, and if the percentage of deaths among the infected is constant, the ânumber of deathsâ increases as well.
- In other words, there are a number of values that are interdependent, and there is a time delay before one value affects another.
- If we draw an arrow of influence, ânumber of deathsâ is downstream, so it changes late, and ânumber of reproductionsâ is upstream, so it changes early, so it is useful to focus on upstream indicators when predicting the future.

I collected this as an example of human bug, but I donât feel like giving feedback to the speaker on this matter.
relevance - systems thinking
