Question 3 of 3
3. Question
Which of these causal links seems consistent with your experience?
Correct
Answer: It seems to us that only (2) is reliably true, and even here you may have wondered. A good question to ask yourself is whether the causal relationship would hold true even “if all else were equal.” In other words, assume nothing else changed and costs to your business increased, would profits fall? Probably. For answer (1), when you become more tired, it is not typical that you would also become more productive all else being equal, so the relationship would be better represented by a ‘-‘. For answer (3), your might have said, “it depends.” For some people who have a choice about their access to energy they might choose to not have energy access so that they can relax, say by going for a walk in the woods. Generally, however, access to energy can improve quality of life and so would be indicated by a ‘+’ sign. It’s OK for it not to be absolutely one way or the other — remember a main purpose of causal diagrams is to get you thinking and having better conversations. There often isn’t one ‘right’ answer.
