903: Extended Mind

2022-05-12T13:08:46Z

Coderchris842: Added a link to the extended mind Wikipedia page

{{comic
| number = 903
| date = May 25, 2011
| title = Extended Mind
| image = extended mind.png
| titletext = Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at "Philosophy".
}}

==Explanation==
This comic refers to the fact that the narrator has become so dependent on Wikipedia as a source of information that although it gives him the great advantage that he appears learned on any topic with a remarkable degree of specificity, the downside is that whenever Wikipedia goes offline, the limitations of his actual knowledge are revealed.

The title, {{w|Extended_mind_thesis|"Extended Mind"}}, refers to a theory proposed by philosophers Andy Clark and David Chalmers, which postulates that the mind not only includes what can be found in the skull, but also incorporates external things, like Wikipedia.

The title text refers to an observed phenomenon that many of Wikipedia's page links eventually lead to the {{w|Philosophy}} page. This may be due to the fact that the first few links in any article tend to reference more general or abstract ideas, which eventually gravitate towards philosophy. This is not actually true, though. It works for the spark plug page and countless others but not for all. The comment section below has some examples, but many of them are not working anymore, because Wikipedia references change in time, as just about anyone can just log in and add/remove links, or just adjust their position in an article. Most instances of this not working are because of endless loops (page A to page B back to page A, or anything like that).

More info on this bizarre characteristic of the encyclopedia can be found {{w|Wikipedia:Getting to Philosophy|on their page about it}} or on [http://matpalm.com/blog/2011/08/13/wikipedia-philosophy/ this blog].

==Transcript==
:[An IM window is open over a Chrome window with tabs for Spark Plug, Feeler Gauge, and Wikipedia.]
:Message with Mike1979
:Mike1979: I replaced my spark plugs and now my car is running weird.
:Me: The spark gap might be off.
:Me: You can check with a feeler gauge.
:Mike1979: What should the gap be?
:Me: Usually between 0.035" and 0.070".
:Me: But it depends on the engine.

:[An IM window is open over a Chrome window with a single Wikipedia tab, marked ERROR. The page says: "Wikipedia has a problem. Try waiting a few minutes and reloading (can't contact the database server: unknown error (10.0.0.242))]
:Message with Mike1979
:Mike1979: I replaced my spark plugs and now my car is running weird.
:Me: What is a spark plug??
:Me: Help
:Me: What is a car??

:When Wikipedia has a server outage, my apparent IQ drops by 30 points.

==Trivia==
*The error code shown in the right panel (10.0.0.242) caused a [https://lists.archive.carbon60.com/wiki/wikitech/236027 bit of a discussion] from the wiki techs. Randall replied with:
::Randall: "I drew it based on an older error message where the IP was 10.0.0.243. I changed it to 242 (a) because I try not to get too specific with those things, and didn't want people poking the actual machine at .243 (if it was still there) - I actually considered putting .276 and seeing how many people noticed, but figured they'd just think I made a dumb mistake. and (b) as part of this ancient inside joke involving the number 242 ..."

*For a few weeks after this comic came out, following the links as explained in the title text would actually lead only to the Science page, due to someone/someones altering the links. The alterations could have been coincidental, good-faith edits, but were much more likely to be vandalism to break this trick. The edits were eventually reverted, and, as of July 2016, all first links lead to the ocean. Er, Philosophy. At least, when they're not stuck in endless loops.

231: Cat Proximity

2022-05-12T13:00:33Z

Coderchris842: Added to the trivia page

{{comic
| number =231
| date =March 5, 2007
| title =Cat Proximity
| image =cat_proximity.png
| titletext =Yes you are! And you're sitting there! Hi, kitty!
}}

==Explanation==
This comic refers to the use of "{{w|baby talk}}" when speaking to pets, especially {{w|cats}}. A person's voice becomes {{w|falsetto}} and {{Wiktionary|cooing}}, vocabulary becomes simplified, and phrases are repeated, such as "Here, kitty, kitty, kitty."

The chart shows that a person's apparent intelligence decreases, and that the {{Wiktionary|inanity}} (i.e. uselessness or emptiness) of their statements increases, the closer they get to a cat.
Most people act like this when they're playing with cats or trying to call them over to them.
Thankfully, being close to a cat doesn't actually cause any decrease of intelligence in normal circumstances; the graph technically refers to ''demonstrated'' intelligence rather than actual IQ levels.{{Citation needed}}

The title text continues [[Cueball|Cueball's]] obvious statement (and thus inane/useless point made) from below the graph.

In [[1535: Words for Pets]], [[Randall]] again mentions how people often talk strangely to their pets.

==Transcript==
:[A graph with the x-axis labeled, and the scale indicated from left to right:]
:Far
:Human proximity to cat
:Near
:[Two curves are drawn and labeled, first the one starting on top, which then veers downwards and crosses the other as that curve veers upwards.]
:Intelligence
:Inanity of statements

:[Below the graph, Cueball is seen standing at three distances from a cat that is drawn to the far right. The two first Cueballs are just standing, one below far, the other in the middle, and the last is standing close to the cat (below near) with his hands up, and he is speaking.]
:Cueball: You're a kitty!

==Trivia==
*This comic is available as a signed print in the [https://store.xkcd.com/products/signed-prints xkcd store].
*If you type cat in [[UniXKCD]] it will print You're a kitty, a reference to Cueball's line in the comic.

2618: Selection Bias

2022-05-12T12:55:00Z

Coderchris842:

{{comic
| number = 2618
| date = May 11, 2022
| title = Selection Bias
| image = selection_bias.png
| titletext = We carefully sampled the general population and found that most people are familiar with acquiescence bias.
}}

==Explanation==
{{incomplete|Created by a DOUSE THAT ROLLS NUMBERS LIKELY TO RESULT IN MORE ROLLS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Blondie]] is [[:Category:Public speaking|giving a talk]] at the conference "Statistics Conference 2022." By show of hands she and the audience learns that most of the listeners are familiar with {{w|selection bias}}. She uses this to conclude that it's a term most people know.

The joke is that she is thus falling for the very thing she's trying to explain. A statistics conference is likely to have an audience consisting of professional statisticians, or at least people interested in the subject, and it is expected that most of them would thus be familiar with any mainstream statistical term, like selection bias. Had she asked a random sample of people in the street, many of them would likely not be sure what selection bias is. This effect is also the subject in [[2357: Polls vs the Street]].

This joke also ties into how statistics as a whole can be highly counter-intuitive and sometimes almost paradoxical, where things like the {{w|Monty Hall problem}} and {{w|survivorship bias}} lead people into thinking the answer to a problem is definitely in a place it's not. That Blondie, presumably a statistician herself, made this kind of mistake is professionally embarrassing but not unprecedented.

The title text refers to {{w|Acquiescence bias}}, which is the tendency of people to respond positively to positive questions, for example "Are you familiar with the famous webcomic {{xkcd}}?" is more likely to generate the answer yes than "Are you familiar with that webcomic for engineers that nobody else understands until they go to [[Main_Page|Explain xkcd]]?" the reason that the general public seemed to know about Acquiescence bias may be because the surveyor themself fell victim to Acquiescence bias.

==Transcript==
:[Blondie is standing on a podium behind a lectern with a microphone. She is standing under a hanging sign with large text. In front of the podium is an audience of five seated persons all with their hands raised above their heads. The audience includes two guys that look like Cueball, Hairbun and two other persons with dark and blonde hair.]
