Irregular Webcomic! #974

Okay, to fully get this one you need knowledge of:

Japanese cuisine. Fugu is a genus of puffer fish, regarded by many Japanese as a delicacy. Unfortunately, its liver and other organs contain lethal concentrations of the highly toxic tetrodotoxin. This is normally removed by the specially trained and licensed chefs who are the only ones allowed to prepare the fish for consumption. But sometimes mistakes are made, and some poison remains in the prepared dish. Diners eating it feel a tingling sensation, followed by paralysis, and death. There is no cure, and a few people die this way in Japan each year.
French language. Poisson is French for "fish".
Statistics. The Poisson distribution is a statistical distribution first described by Siméon-Denis Poisson, a French mathematician who lived from 1781 to 1840. The distribution describes the expected number of events of a fixed probability occurring within a fixed interval of time - such as the expected number of deaths due to fugu poisoning in Japan in a year.

Et voilà!

As pointed out by a reader, the graph shown on the screen in this strip is in fact not strictly a histogram, but a bar graph. The difference is that the bars in a histogram always abut each other without any gap in between. Dealing with histograms for my work on frequent occasions, I should certainly have not confused them. I think I in fact tried to make a histogram, but was defeated by good old Microsoft Excel's stupid graph formatting functions.

2014-12-09 Rerun commentary: Working at a workplace with several Japanese people, and also several non-Japanese people who are Japanese food enthusiasts, the question occasionally arises of whether anyone has tried fugu. Or indeed would be willing to try fugu.

One associate told me he likes fugu, and the faint numbing sensation it leaves on the lips when properly prepared.

I, on the other hand, have never tried it, and will not do so willingly. I understand the risks are small, and I probably accept a similar level of risk every time I cross a street. But still, there's something about the faint possibility of dying horribly just because I tried eating something which I could easily have said no to which puts me off.

Risk assessment is a thing we humans do very poorly, and it is coloured by personal experiences and gut instincts more than a logical analysis. There's no easy way around it, unless you happen to be a Vulcan.
