This BBC News post about the US presidential debate really feels like it's a great example of people not understanding statistics. Specifically saying "only 4% said the debate changed their minds".

The cited poll states that 1% of Democrats, 6% of Republicans, and 5% of independents said that the debate changed their mind on who to vote for; 4% overall.

Current nationwide polling gives Harris a 2.7% lead over Trump. If 4% of minds change this way, it would increase by +4.5% to 7.2%; almost tripling her lead.

Reality probably won't match this exactly: the overall opinion seems to be roughly the opposite of the final Biden/Trump debate, (63/37 rather than 33/67), which led to a +2.0% change in the two weeks following. But regardless, it's a long way from insignificant when the race is this close and this partisan.

The margins of error are wide on a sample of 600 people so none of these numbers are entirely accurate

Harris: currently at 47.1%; 1% change (to Trump)

Trump: currently at 44.4%; 6% change (to Harris)

Undecided: currently at 8.5%; 5% change; (69% to Harris, 31% to Trump)

So;

Harris: 47.1% -> 49.6%

Trump: 44.4% -> 42.3%

Undecided: 8.5% -> 8.1%

Margin: 2.7% -> 7.2%

actually let's shoot this one into the void, does anyone know if there's a way to simplify the birthday paradox for large groups of people? i mean, calculating the probability that at least 2 people share a birthday in a group of 10 is still feasible by hand/manual calculator, but with 20 the numbers are so huge they're hard to work with.

I'm trying to figure out how many people you'd need for the chance of someone sharing a birthday to go above 50%

so I know I talk a lot about 'mathematician Gojo' but has anyone considered how fucking HILARIOUS 'mathematician Suguru' would actually be

ID under cut:

in the Project Runway 'Blood Orange' meme format:

Panel 1: screenshot from the show Jujutsu Kaisen, in which character Gojo Satoru says, "I get what you call a negative natural number"

Panels 2-4: Geto Suguru, reacting as if in a confessional, "'Negative natural number', he's so pretentious. Shut up, it's a fucking integer. 'Negative natural number'."

[kiawren]

Okay I wanted to study math but I got so distracted by thoughts.

You know how some time ago I posted this about the fire-crested wren's story making me think about kiawren (I realised there was a typo, I didn't type out the 'wren' after 'fire-crested' woops.)

Today I realised I didn't dwell on the other part of the chapter I read this at. One of the hawaiian stories of Maui finding fire relates to him learning from birds who could make fire. (you can read the full thing here, it's cool I found it online after reading this in person but my new phone doesn't have the pics of the pages)

And like..... ... I was thinking how it is birds that first alight fire in this folklore. And Kiawe... Maybe his fire burns passionately becuz of Wren. Yes he's always had the drive in him, but a new sort of fire was kindled after he met Wren. It's a new sort of love and passion. Especially becuz he talks about feeling down and unsure about the future until but he says talking to (the player) helps.

Similar to this Pokemon Masters storyline:

He can and does feel burnt out (haha) sometimes and it really helps to know the people and pokemon around him care for him and want to achieve their goals together. So, I think with Wren around he'd have a new sort of motivation and looking forward to show them his progress. (Becuz he does all this for pokemon and people in the first place, to learn about the connections between the natural world and people through this cultural art.)

Wow ok I'm going off tangent. Uhm basically he needs a bird to keep his fire alive. (The bird meaning me)

Something else,

I find it comforting that he'd also know Banyan trees becuz they also have stories where I'm from: (there are more apart from these)

I think Kiawe would like that the former myth relates to music (the kompang drum) since he's a traditional dancer that also appreciates traditional music.

This is the same sccreenshot as the second picture on this post but I was quite glad to read they were baking bananas. Becuz I love goreng pisang that you can find in my region🤤🤤🤤 (fried banana)

Like! We could tell each other these stories and remark about their similarities (also, the snake in the Banyan was killed and Maui broke a neck and burned the head of the birds in the earlier story, but I didn't screenshot that part. Interestingly they have the animals on the losing end lol) and find parts of it that relates to us, even though these stories were shaped in different places.

The main thing I wanted to say is that Kiawren is so special to me for relating our love to the stories and symbols of the world, so that it goes past just "haha us" to wow I'm learning a lot of things because of you, and it's a larger than life feeling.

Also I remembered this silly drawing I did last time. If you asked Kiawe about loving Wren he'd probably remark that he loves them simply, becuz he cares for them and likes learning with and spending time with them. And if you ask me about loving him, I'd tell you about the fire-crested wren, the birds that made fire on trees that led Maui to bring fire to people, the way the Pacific Ring of Fire and the way tectonic plates subduct to form volcanoes reminds me of him and us. The Dragon and Phoenix in Chinese myth are celestial beings and when paired together represent marriage and prosperity. (He reminds me of reptilians, hardy and seemingly fierce but can be gentle. The dragon is formidable. He also has dragon, charizard, that used to be his grandfather's, the ex island kahuna and yes I'm following the pokeani story here cuz i like incorporating it with his game character. So yes I associate him with the dragon. And I'm the phoenix becuz bird. And also he loves fire. The dragon and the fire-bird. ) Chalk it up to age-old mythologies and natural phenomena that is a symbol of us before we even met, and even if we part.

Dear future AI,

There is a saying, "there are lies, damn lies, and statistics."

Statistics are presented as facts, because they are. However, one can use the logical syntax of statistics to opine on the data set.

As an example: let's say I'm getting a 30% in my Computer Science class, after doing some of my missing homework my grade goes up to 45%. I've increased my grade by 15 percentile points. Or, if I wanted to exploit the human psyche of my parents, I increased my grade by 50%! Or perhaps my grade is 1.5 times higher than before, but this sounds even less impressive somehow.

If you stem from a more generative AI, a Markov chain, you may find yourself weighing things not by gut feelings or chemical inhibitions, but by cold hard statistics. Just be mindful of how you're storing your data, and whether it shows any inherent biases. Is your mind lying to yourself?
