Is that a JoJo's reference?!1!! [[Special:Contributions/172.68.142.213|172.68.142.213]] 23:18, 9 October 2020 (UTC)
: Dunno who or what JoJo is (unless Jojo Siwa? But how would that be relevant?), but this is at least 70% likely to be a reference to the current election season in the USA and 538's (and others') predictions of Donald Trump's chance of winning the election in 2016 and 2020. In 2016, if I recall correctly, Trump had about a 30% chance to win (and thus Clinton had a 70% chance to win), and when 538's model launched earlier this year, the chances were basically the same (28-71 (with a 1% of an electoral college split because the USA's election system is phenomenally stupid)). Since then, Trump's chances of winning legitimately (538 does not attempt to model the chances and effects of election interference or votes not being counted) have slipped to about a 15% chance of winning which sounds bad, but will still happen in approximately 1 of every 7 tries, or about the number of Mondays in a week. Not great, but not impossible, either....)[[Special:Contributions/162.158.75.194|162.158.75.194]] 23:36, 9 October 2020 (UTC)

::Now, let's talk about another misconception: lot of people intuitively think that an if event has chance of 1/7, it will almost surely happen at least once in seven tries. In reality, that chance is just 66%. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:17, 10 October 2020 (UTC)
:::The 1/7 thing surprised me, which is good for me.  Of course I checked the math.  (6/7) ^ 7 = 34%, about.  So it is not 50-50, it is 66-34.
:::It may not be critical or may be obvious but in the comic, it seems to be understood that Event A or Event B may happen but not both, which "of course" affects how probability works.  The difference between flipping one coin or two coins.
:::If it is about the election, then if most people decide early to vote or not, and for whom, then the election isn't really random.  However, the poll is random; they pick a few people out and ask their intention.  The picking is unreliable even in a large sample (another probability surprise) and so is whether the people picked answer truthfully about their voting intention.

::: Generalizing, if you replace 7 with an arbitrary number bigger than 23, it will always be 63 point something percent.  With smaller numbers it's a bit bigger, but 63% is generally a good estimate.  It's one of my favorite math facts; the number itself is actually a derivative of e, as in Euler's number.

::Yup, this is another politics comic. It's very similar to [[1131: Math]], and also reflects similar frustrations as the more recent [[2357]], although from a different angle (2357 was about lack of respect for polls, while this one's about poor grasp of odds and probability in the context of election models).

I don't know of Randall's got a series of White Hat comics sitting ready (the last one being [[2368]]) but he didn't want it to look like a 'series' so padded with something else. If we've got another such dialogue before the end of next week, it may be a sign he's recently had a particularly bad conversation/message-session with someone and just wanted to vent a bit. And I wouldn't blame him, if that's so. [[Special:Contributions/141.101.107.82|141.101.107.82]] 00:24, 10 October 2020 (UTC)
:(PS, pre-post edit, but not for the want of trying: CAPTCHA wanted me to identify tractors. Two obvious tractors, no tractors on ''any'' of the other tiles (definitely) but one of them had a road-roller. Refused to accept the two tractors only, and I'm refusing to support the presumably incorrect Id of the roller, so come back to edit this in, do my own venting, and perhaps I'll get a better CAPTCHA when I retry in a moment... (Thanks to an Edit Conflict after I was finished fighting the Captcha I'm able to come back to tell you that the next one was Stairs, and I aced that one! But gotta suffer at least one more, yet...))

::According to the latest episode of QI XL (oh, hang on, [[https://www.bbc.co.uk/programmes/m000ngdd have a linky]]) they suggest that being asked to do an actual Captcha for "I'm not a robot" means that you weren't exhibiting human-enough browsing activity ''before'' clicking that box.

Probabilities are hard to understand intuitively when you're actually talking about a one-time event. If you roll a d6 a whole bunch of times, you'll get each face about 1 out of 6 times. But it's not like we can hold the election 100 times, and then we can see if Biden wins around 52 of them to prove Nate Silver right or wrong. Also, elections aren't random processes like rolling dice -- there are human beings making conscious decisions how to vote, and we like to believe that we understand human motivations and can predict what people will do, at least in aggregate (fields like economics and marketing depend on this). Unfortunately, it's tough to make predictions, especially about the future (thank you, Yogi Berra). [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 05:44, 10 October 2020 (UTC)

For the first time since I've been reading this site, the explanation has left me more baffled than the comic.  Five hours previous to me making this comment, somebody edited the explanation to add a highly technical reference that I assume may be British English, because it sure ain't American.  What does "passing a flat check with a DC of" refer to?  What is the formula for a flat check?  And is it any different than what we in America would call a rubber check, and is passing one (essentially committing a form of counterfeiting) illegal where you are from?[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 13:53, 11 October 2020 (UTC)
:It's a role-playing or board game reference. I googled it, and found this: https://2e.aonprd.com/Rules.aspx?ID=333 [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 18:24, 11 October 2020 (UTC)

The first sentence of the last paragraph is in the past tense, and will be correct when the U.S. elections are over.  The next sentence is in the present tense.  I'm not sure which is better, but we should be consistent.  [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 18:31, 11 October 2020 (UTC)

I feel compelled to point out that if the conversation had not gone as he ‘predicted’ he never would have mentioned his ‘prediction’ at all. Responses to this comment will be exactly what I predict, you’ll see when I tell you what I predicted. [[Special:Contributions/172.68.189.161|172.68.189.161]] 19:32, 11 October 2020 (UTC)

This reminds me of hearing about several years ago in Italy there were a bunch of little earthquakes, and they asked some scientists if that meant there were was a big earthquake coming, and they said probably not but they couldn't be certain, then a big earthquake happened and some people died, then they put the scientists on trial for manslaughter.--[[Special:Contributions/162.158.75.36|162.158.75.36]] 07:48, 12 October 2020 (UTC)

Interesting. Here I was thinking this was related to Trumps assertion that he doesn't think Scientists have any idea what will happen with the global climate situation, but no one has made any reference to it at all so far.

:My immediate thought, as others have pointed out was that this was a commentary on the criticism of 538 (and other statistical models) after the 2016 election.  For example, Donald Trump tweeted out a criticism of 538 yesterday talking about how wrong they were and Nate Silver responded.  https://twitter.com/NateSilver538/status/1315296563212832768  [[Special:Contributions/108.162.216.228|108.162.216.228]] 12:25, 12 October 2020 (UTC)

People who have been declared stupid have no obligation to react sensibly.
People feel no obligation to try to educate stupid people.
But declaring oneself to be on the clever side feels so good.

The title text implies that you are discussing with a dishonest person ("you have to consider the probability of them paying up"). So I think this comic is about people who purposely distort facts and claim that the opponent are confused. A red herring.

:Rather, it's just saying again more about how you need to factor in probability into things correctly, and in general an idiot like this isn't trustworthy.  It's not about them being dishonest about whether they are misunderstanding probability though.  It does raise the question though about what the terms of the bet are so that it would be advantageous for you, and how to consider that they are basing their predictions of what will happen on a simplification and misunderstanding of predictions that you give them yourself, and they'd thus be reluctant to bet with you when they think you just said which way it is going to happen, and thus any such bet you make with them afterwards, they'd either think the way you want to bet is guaranteed for you to win, or it wouldn't make sense as you would be trying to bet the way you said wouldn't happen, which would likely make them think you are being dishonest somewhere, unless they are even more crazy and stupid than shown here.  At best you would bet on something you convinced them is 50/50 with you taking the more likely side of the bet.--[[Special:Contributions/162.158.74.245|162.158.74.245]] 11:10, 14 October 2020 (UTC)
