Explain xkcd: It's 'cause you're dumb.
The chart shows that things toward the right are scary, while things toward the top sound scary, without necessarily being scary.
This humorously explores the how things are often named colloquially and without regard to accuracy in correlating actual scariness with apparent scariness. It is interesting to note how people react to the items near the bottom right of the chart "scary things with not-very-scary names" when compared to how they may react to items in the upper left "not-very-scary things with scary names". Some of the entries on the chart are especially interesting examples considering that portions of the names that are associated with significant historical or cultural events and themes. IE: Chernobyl Packet, Demon Core.
The table below list the entries from least to most scary (including the entry mentioned in the title text). The assigned percentage values assumes a linear scale and assigns flesh eating bacteria with the point (100%, 100%). As there is no mention of the scale this is simply the easiest way to list the entries. As is clear from the title text there are things more scary than 100%!
|| True Scariness
||A network packet that induces a broadcast storm or network meltdown.
||A device for measuring heat of combustion of a reaction in a pressure vessel.
||A chemical warfare agent which causes blisters and severe irritation on skin and lung tissue.
||A hypothetical scenario where low Earth orbit objects collide, creating space debris which increases the risk of more collisions, leading to a cascade effect which could severely hinder space exploration and satellite technologies for many years.
||A phenomenon where wet soil loses its strength, leading to potholes, road and terrain damage, and even building collapses, especially after earthquakes or torrential rains. Liquefaction can cause landslides; landslides can cause more liquefaction.
||A hypothetical end-of-world scenario where self-replicating nanobots consume all matter.
||An illness caused by strains of influenza adapted for birds, which is generally very deadly in humans. Should the virus adapt for human to human transmission, a pandemic can quickly result. Since birds can travel great distances quickly, it is generally already widespread and difficult to contain.
||A subcritical mass of plutonium that was involved in two separate fatal incidents at Los Alamos laboratory in 1945 and 1946. In both cases, the core was accidentally placed into a configuration where it went supercritical and exposed an experimenter to fatal doses of radiation. The second is more notable, where Louis Slotin held two halves of a beryllium neutron reflector apart with a flat head screwdriver which slipped, suddenly causing the contained plutonium core to become supercritical and delivering a fatal dose of radiation.
||An uncontrolled nuclear reaction. This occurs when a system running at exact criticality experiences an increase of one dollar of criticality (a term devised by Louis Slotin, as seen above).
||Antibiotic resistant bacteria. The growing use of antibiotics has caused some bacteria to evolve to become resistant to the antibiotics. A superbug refers to a scenario where a bacteria evolves to become resistant to all antibiotics, for example, MRSA.
||An aluminum Zero Halliburton briefcase which is used by the President of the United States to authorize nuclear attack. A military aide carrying the football is always near the president.
||As the name suggests, bacteria that eats (or more accurately, releases toxins that destroy) your skin and muscle.
||This scenario is also in the title text of 683: Science Montage: "...We have a Helvetica scenario!". The scenario is a fictional experiment, presented in Switzerland (Helvetica), which assumes that removing only the nucleus (the center of an atom) of a calcium molecule in one's skin, but still leaving the electron shell at its position, would cause a massive reaction ending up in heavy mutations.2 The Helvetica scenario was made up by the BBC comedy show Look Around You in the pilot episode, which can be seen here (at 6:29). The fact that the term Helvetica is more commonly known as referring to a very-commonly-used modern typeface makes the name sound like it should refer to a much less serious situation.

- [A scatterplot, with the y-axis labeled "scariness of name" and the x-axis labeled "scariness of thing name refers to.
- At the top-left is "chernobyl packet".
- Slightly right and downwards of that is "bomb calorimeter".
- Towards the middle-top is "kessler syndrome".
- Towards the middle-bottom is "soil liquefaction".
- Towards the center is "mustard gas".
- Along the bottom, two-thirds of the way to the right, is "grey goo".
- Slightly up and to the right from that is "criticality incident".
- About midway up from there is "bird flu".
- Further up, not quite at the top, is "demon core".
- Back towards the middle vertically, but slightly farther to the right, is "superbug".
- Almost all the way to the right but still near the middle vertically is "nuclear football".
- At the far top-right is "flesh-eating bacteria".]
- Zero Halliburton
What is "A Zero Halliburton briefcase"? 126.96.36.199 13:24, 24 July 2013 (UTC)
- Zero Halliburton is a luggage brand name, with a line of aluminum attache cases. Not connected to the big company Halliburton, associated with former US Vice President Cheney and the war in Iraq. Wrybred (talk) 13:57, 24 July 2013 (UTC)wrybred
- The history of Zero Halliburton luggage does intersect with the founder of Halliburton Company, Erle P. Halliburton. He needed rugged cases, so he started a company to produce them. He sold it to Zero Corporation. . — tbc (talk) 14:26, 24 July 2013 (UTC)
- Military Aide/Secret Service Agent
Isn't the nuclear football carried by a military aide, not a Secret Service agent? 188.8.131.52 14:18, 24 July 2013 (UTC)
- Probably. I don't really know what I'm talking about. If you think you can improve on what I wrote, go for it! RouterIncident (talk) 14:24, 24 July 2013 (UTC)
- Yes. "Cheney noted that the president is accompanied at all times by a military aide carrying a 'football' that contains launch codes for nuclear weapons.  — tbc (talk) 14:26, 24 July 2013 (UTC)
- I assume it's called 'football' because in the USA footballs are usually carried by hand. --Chtz (talk) 15:16, 24 July 2013 (UTC)
- Early plans for nuclear war against the Soviets were codenamed "Dropkick". 184.108.40.206 16:23, 24 July 2013 (UTC)
- Helvetica Scenario
I think the "Helvetica Scenario" explanation is wrong, but I don't know enough about it to feel comfortable editing. Here's an article I found that makes more sense. http://enigmauniversity.wikia.com/wiki/Helvetica_Scenario (I didn't watch the Youtube clip since I'm at work, so maybe that's what the clip refers to. It should be explained in the article instead.) Trek7553 (talk) 14:45, 24 July 2013 (UTC)
- To the best of my knowledge, the page you linked to is a work of fiction on a role-playing wiki. The references to calcium imply that it is based off of the Look Around You segment, but with its own added elements for the sake of role-playing. RouterIncident (talk) 14:53, 24 July 2013 (UTC)
- I changed this section. The video is correct, but the horror scene is just showing a possible result of the Helvetica experiment.--Dgbrt (talk) 16:19, 25 July 2013 (UTC)
- That sounds much better now. RouterIncident (talk) 18:06, 25 July 2013 (UTC)
- I know what you mean but I like the statement "...the page you linked to is a work of fiction..." - the Helvetica Scenario is a work of fiction! But yes, that is a derivative work, the original source being Look Around You.
- Having just looked at the edits, Dgbrt is getting seriously confused. The Helvetica Scenario is not real, and is completely made up by the TV program Look Around You. Urban dictionary is entirely based on the original invention by L.A.Y. It is not a real thing!
- Arbitrary Scariness Formatting
I have a slight issue with the artificial percentage scale given for entries in the chart. First of all it assumes a linear chart that is measured in percentages. Secondly, it assumes Flesh-eating Bacteria is 100% scariest thing and scariest-sounding thing existant. Just because it's the highest on the chart doesn't make it "100%" (again, percentage seems like an arbitrary scale to assign) TheHYPO (talk) 16:22, 24 July 2013 (UTC)
- I disagree on your second point. The explanation expresses the scariness of something as a percentage of Flesh-eating Bacteria BECAUSE it is an arbitrary scale. It doesn't imply that the bacteria is the scariest possible thing. I think this is the best way; it's better than saying "Grey goo isn't as scary sounding, but is scarier than..." for all possible combinations of every item.
Also on your first point, it doesn't assume the chart is measured in percentages (although it does assume linearity). 220.127.116.11 12:30, 25 July 2013 (UTC)
- How about we just give the pixel coordinates and point out that the scale is arbitrary (or not defined by the comic). Percentage would suggest that the scale is in some way linear, which you actually cannot conclude from the graph. --Chtz (talk) 13:08, 25 July 2013 (UTC)
- Initially I had written out "Not very scary", "Somewhat scary", "Fairly scary", etc. but it seemed simpler and much easier to read and sort to simply use arbitrary percentages. RouterIncident (talk) 14:55, 25 July 2013 (UTC)
- As there are no values or units listed, Randall's dots are fairly arbitrary, probably plotted relative to each other and to a roughly-equal apparent-to-actual-scariness line. So isn't it a little silly to argue about the listing of an arbitrary scale for these arbitrary values? 18.104.22.168 15:57, 25 July 2013 (UTC)
- In my opinion the percentages are over interpreting the comic. But since it is here it should be explained as position on the graph relative to zero.--Dgbrt (talk) 16:19, 25 July 2013 (UTC)
- The percentages are perfectly fine. They just need to be interpreted as what they are: percentages of scary, relative to flesh eating bacteria. Flesh eating bacteria = 1 unit of scary. In this situation 110% isn't just a metaphor. If the bacteria was the scariest thing nothing would be off the chart. db (talk) 06:11, 17 November 2013 (UTC)
Really I think the point of the comic is how superficial perception and reality fail to correlate. That's what is so notable about flesh eating bacteria. It lives up to it's name. A rare thing indeed. db (talk) 06:11, 17 November 2013 (UTC)
What is missing about the transcript? It describes the comic panel perfectly. there is no dialogue to include. could you please be more specific about what you feel is missing from the transcript? @dgbrt Mrarch (talk) 00:37, 3 December 2013 (UTC)
- A transcript should not contain a sentence like: "Items within the scatter plot are listed in the table above." --Dgbrt (talk) 11:02, 3 December 2013 (UTC)
