Ponytail: Our research shows that compared to the overall population, people who agree to participate in scientific studies are less likely to call the police to rescue them from our lab.

The selection effect is a bias in the results of a study because the study participants are not a random sample of the general population. For example, a study performed on college students may be biased toward better-educated people, or a study on social interaction may be affected by how many participants have the same first language as the investigators.

One more comic until we hit 2000! Which means on July 11th, the comic number will finally match up with the date (and will certainly be the only time ever). Like an eclipse! Some Commenter (talk) 12:23, 28 May 2018 (UTC)
- Just 49 to go until a big round-number milestone! (and just 1 until a big round number kilometerstone) --172.68.54.4 21:54, 28 May 2018 (UTC)
- Well, arguably only two more to go, as there was no comic for #404 (Found this out on accident a few minutes ago looking for something unrelated.) But that means the 1000th comic was the 999th too.Linker (talk) 12:47, 29 May 2018 (UTC)
There was no comic #404 because Randall intended the "Page Not Found" error as comic #404. The Dining Logician (talk) 20:18, 29 May 2018 (UTC)
As I recall Mr Munroe's 404th comic was something that he created to mess with us: I remember being surprised by it, looking at the source code of the page and deciding that it was not an error.

I don't think escaping from MRI is that easy. There is reason why it's known to be problem for claustrophobic people. -- Hkmaly (talk) 22:46, 28 May 2018 (UTC)
- It it not that it is hard to escape from an MRI, unless you are somehow restrained or disabled. It is just that it feels that way because your head is in a tunnel. 141.101.88.220 13:31, 29 May 2018 (UTC)
- Is it dangerous to leave an MRI mid-scan? 172.68.189.115 18:57, 29 May 2018 (UTC)
It could be if your escape attempt brings something metallic into the MRI field. The Dining Logician (talk) 19:37, 29 May 2018 (UTC)
Should we mention trivia of comics using the same platform? https://xkcd.com/1781/ 172.68.65.252 16:58, 29 May 2018 (UTC)
https://xkcd.com/1453/ is a simliar, meta-research thing comic. There seems to be several of these now, perhaps a category or at least a mention should be appropriate? 172.69.186.28 08:03, 30 May 2018 (UTC)
