Maybe not a representative sample
The Dominion Post asked motorists why they thought the road toll had climbed, and what should be done about it.
Interestingly, three of the five(middle-aged, white, male ,Wellington area) motorists attributed it to random variation. That’s actually possible: the evidence for a real change in risk nationally is pretty modest (and the Wellington region toll is down on last year).

I would love to know the wording of the question that was posed. I find it remarkable that 4 of the 5 men included the words “statistical”, “variation”, or “random” in their answers.

I would have thought, based on the headline, that they asked “Why do you think the road toll has climbed?” I agree it would be good to know for sure.

Comets [most not all] have traditionally been associated with bad luck and accidents.
Moons and lunacy have very strong correlation, possibly causation for some.
Drownings for this holiday period have also nearly doubled from last year, when the non specified Kariotahi Beach surfers drowning is included. At present the cause of death is not specified.
Much of the variance within statistics has reasons beyond the grasp of modern empirical thinking.
Look for ancient [or modern alternative]reasonings to explain baffling variance.
Alternative archaeology places vikings in america before columbus, and early celtic and possibly chaldean evidence in some ancient nz sites.
