# Talk:925: Cell Phones

On first read I thought the joke is that the cell phone graph shape (somewhat) closely mimics the shape of the cancer graph, including the part where it begins to level off - implying that one linearly correlates with the other, with a 20 year delay (a typical time it takes for cancer to manifest, except in this case it's backwards). ultramage 14:17, 22 December 2012 (UTC)

That and the fact the graph is out by a scale factor of 1000 is always a fun way to screw over how the statistics look. 82.16.27.115 (talk) (please sign your comments with ~~~~)

The real problem with the graph is that it makes it look like cancer rates have increased from near-zero levels to way higher since 1970, until you actually read the Y axis and see that it's gone from about 400 (per 100,000) to about 475. This is an increase of only 18.75%, as opposed to the visual appearance of a 300% increase. Hats off to Black Hat!! 108.28.72.186 01:18, 7 August 2013 (UTC)
Among the many things wrong with the graph is the lack of context. Much of the increase in cancer incidence in the 80s was the availability of pre-clinical testing for prostate cancer[1]. The other is the improvements in control of infectious disease, and more recently heart disease, resulting in an enlarged elderly population who are more at risk of cancer. 141.101.98.99 (talk) (please sign your comments with ~~~~)

I thought the laptop joke was that some people believe not to put it on your lap because it messes with your reproductive organs! ~JFreund

But you know now you are wrong, correct? 108.162.219.223 06:59, 21 January 2014 (UTC)
If your laptop starts messing with your reproductive organs, you may want to either tell an adult, or stop taking drugs (or possibly take more drugs). 108.162.237.218 06:45, 3 May 2014 (UTC)

I originally thought that the graph was supposed to show that an increase in cellphone use caused a decrease in cancer. I'm not sure why Randell didn't go with that conclusion, as it seems way more obvious to make when you look at tha graph, and it's humorously the opposite of what people are saying. Still very silly, of course :p Maplestrip (talk) 08:37, 31 October 2014 (UTC)

For all the fun publicity this gets, I agree -- the graph doesn't really make it look like cancer causes cell phones, but rather that the leveling off in the growth in cancer rates causes an increase in cell phone use. Not as funny stated that way, for sure, so I get why XKCD didn't go that way. 173.245.54.133 13:27, 24 July 2015 (UTC)

Why does the title text explanation refer to panel 2? From what I can see the title text either refers to a) you should not hold your laptop by its screen as it may damage it (in panel 2) or b) you should not not rest your laptop on your lap as it may overheat and damage you (in panel 4). I think a) makes more sense since the comic refers to how black hat "holds" the laptop, but I can also see that b) references the subject of the comic. 141.101.98.177 10:19, 22 November 2014 (UTC)

When brash well educated young men from good homes start using dolls as good luck fetishes the sergeants in charge of their ground crew should have a word with their squadron leaders about such people suffering stress.

Unfortunately there was a shortage of pilots and there was no medical help for anyone who Lacked Moral Fibre. Plus the Air Ministry was, in a large measure, responsible for the aggressive attack of the disease initially.

OTOH of course, it was all a long time ago and most of them are dead by now.

(Might have stopped some using IFF over enemy territory though. (Pity, that.))

Whoever included the socks comment in the explanation, I just laughed harder at that than at the actual comment. Props Bbruzzo (talk) 00:30, 15 August 2015 (UTC)

I think it's worth noting that Black Hat says "Just to be safe, until I see more data, I'm going to assume cancer causes cell phones." When I first read the strip, I thought it was a play on how empirically, one wants to assume that there is zero correlation whatsoever. Instead of being safe by assuming there is no correlation, Black Hat assumes that the correlation is there (albeit backwards compared to the norm). However, in retrospect, Black Hat may consider cell phones to be an ailment and wishes to prevent or avoid them, just as someone who believed cell phones cause cancer might stay away from cell phones, "Just to be safe". Makes sense to anyone? Viperzer0 (talk) 07:41, 18 March 2017 (UTC)
