The whole "the brain isn't fully mature until age 25" bit is actually a fairly impressive bit of psuedoscience for how incredibly stupid the way it misinterprets the data it's based on is.

Okay, so: there's a part of the human brain called the "prefrontal cortex" which is, among other things, responsible for executive function and impulse control. Like most parts of the brain, it undergoes active "rewiring" over time (i.e., pruning unused neural connections and establishing new ones), and in the case of the prefrontal cortex in particular, this rewiring sharply accelerates during puberty.

Because the pace of rewiring in the prefrontal cortex is linked to specific developmental milestones, it was hypothesised that it would slow down and eventually stop in adulthood. However, the process can't directly be observed; the only way to tell how much neural rewiring is taking place in a particular part of the brain is to compare multiple brain scans of the same individual performed over a period of time.

Thus, something called a "longitudinal study" was commissioned: the same individuals would undergo regular brain scans over a period of mayn years, beginning in early childhood, so that their prefrontal development could accurately be tracked.

The longitudinal study was originally planned to follow its subjects up to age 21. However, when the predicted cessation of prefrontal rewiring was not observed by age 21, additional funding was obtained, and the study period was extended to age 25. The predicted cessation of prefrontal development wasn't observed by age 25, either, at which point the study was terminated.

When the mainstream press got hold of these results, the conclusion that prefrontal rewiring continues at least until age 25 was reported as prefrontal development finishing at age 25. Critically, this is the exact opposite of what the study actually concluded. The study was unable to identify a stopping point for prefrontal development because no such stopping point was observed for any subject during the study period. The only significance of the age 25 is that no subjects were tracked beyond this age because the study ran out of funding!

It gets me when people try to argue against the neuroscience-proves-everybody-under-25-is-a-child talking point by claiming that it's merely an average, or that prefrontal development doesn't tell the whole story. Like, no, it's not an average – it's just bullshit. There's no evidence that the cited phenomenon exists at all. If there is an age where prefrontal rewiring levels off and stops (and it's not clear that there is), we don't know what age that is; we merely know that it must be older than 25.

something that drives me insane on a relatively regular basis as a body jewelry understander is talking to people who have sensitive skin who are like "oh well I just can't wear any earrings without my ears getting inflamed" and I say "well what have you tried" and they say "well I've tried sterling silver and I've tried gold..." and it's like. ok. I don't know how gold and sterling somehow got spun by the jewelry industry as being especially good for sensitive skin but whenever I'm like "well have you tried implant grade titanium" they're always like "no....... but I've tried sterling silver... and it didn't work ..." like. I don't know how this narrative about sterling silver somehow got so strong but when they put pins in your fucking legs when you snap your leg in half are those pins made of sterling silver or are they made of implant grade titanium or surgical steel????????? HELLO. HI. YOU MIGHT BENEFIT FROM TRYING IMPLANT GRADE TITANIUM I AM JUST SAYING

Over 6 months in the making (mostly bc procrastination) but I finally compiled my Kanto Gym Leader Magazine series. I love the idea of an in-universe style fashion publication where they all do interviews about their hobbies and stuff

Want something like this for your own OC? My commissions are open!!

Alright, I think I like tumblr now.

A pun post crossed my dash, and I reblogged it with an equally bad pun in return. A couple of my followers find it funny, it's a good day for everyone.

That was on July 7th.

Virality on Reddit was entirely algorithmic. You could garner a couple crossposts, but the success of a post was entirely dependent on whether or not it hit r/all--the main page of Reddit. If your post does that, it's immediately exposed to 10x the number of people and immediately gets upvoted.

On my pun post, I get a couple reblogs. And those reblogs get a couple reblogs--nobody really adds any content to the post, it just gets a couple reblogs here and there.

There's a specific chain of reblogs that I'd like to focus on. The most popular post on this chain has about 25 reblogs on it. Half the posts have three reblogs or fewer. Five posts in this chain have just one reblog total.

But the reblog chain keeps going. And going. It breaches containment many times over. And finally, after a chain THIRTY SIX posts long, at 9:30 AM, July 22nd this morning, it hits a popular account.

99% percent of the people who have seen the post--virtually unchanged from how it left my dash--have seen it because it was curated by 36 different people. That's insane to me.

None of those 36 people know that they're part of this chain. They saw a post, reblogged it, and moved on. If any one of these people had not reblogged, the post would have a fraction of the impact it has.

And yet, after two weeks, the post has effectively hit the main page of tumblr. It was picked up, only because people liked it enough to show it to their followers. There were no algorithms necessary.

You really, truly, cannot get this on any other website.

I walk in to naruto’s house kiss him full on the lips make him moan and hinata just keeps knitting crazily as if she is re-knitting the very fabric of her and my pathetic reality

unfortunately for shuro the simple fact is that he’s just way too normal for falin….. marcille on the other hand as much as she might deny it is a fellow fucked up freak and thus was always destined to pull the resident Weird Girl™

I'm so sorry, Marcille, that none of these people have good fashion taste

Not my usual content, but I made something I wanted to share...

[Art description: A Pokémon-themed comic featuring OP as a Pikachu. Long description follows.

1. The tips of Pikachu’s ears are shown with text that says, ‘I’m a Pikachu / My world is filled with lots of cool stuff. Sometimes it feels like anything is possible!’ Under this is a collage showing a Charizard, a Pidgeotto, a Nidoking, an Eevee, and an Ivysaur, all in the background as the Pikachu looks up in wonder. Text reads, ‘All sorts of types, all sorts of attacks, all sorts of Pokemon.’

2. Text says, ‘But...only two ways a Pikachu’s tail could look.’ Two boxes in the upper corners show the male and female Pikachu tails, respectively. The male has a rectangular end to his tale, and the female has a heart-shaped end to hers. Text continues, ‘So then, what am I?’ A large drawing of the narrator Pikachu is shown, with an arrow pointing to their tail, whose end is split somewhat like scissors and doesn’t match either the male or female drawing above.

3. Text says, ‘Too pointy to be [female], too much of a V-shape to be [male]. I thought there was something wrong with me.’ Under this are three cascading panels showing the Pikachu from below at an angle emphasizing their tail. The second panel shows mel further away, and in the final panel she have disappeared entirely. Text on the panels reads, ‘I felt / very, very, very / alone.’

4. Text says, ‘But then, something happened. I found others like me.’ The art shows the narrator reaching out to another Pikachu. Under this are three other Pikachu. One has a rounded tail, one has a tail that has been stitched up to be rectangular, and one has a tail with a slight spike at the tip.

5. Closeups are shown of each of the tails from the previous panel, with text that says, ‘Round tails, scarred tails, spiky tails.’ Under this is a drawing of the Pikachu all hugging with lightning coming from their cheeks. Text reads, ‘They told me nothing was wrong with me, and I wasn´t alone anymore.’

6. Text says, ‘There are many ways a Pikachu’s tail can look. I’ve heard there’s at least over 30 different variations.’ Under this are two panels. The first panel shows the narrator lying on their back on a background of male and female symbols. Text reads, ‘Some days are still hard.’ In the second panel, the Pikachu with the scarred tail is shown with text that says, ‘My friend tells me her tail used to look just like mine. It was taken from her.’

8. The narrator is shown sitting and looking upwards. Text reads, ‘Some trainers won’t accept Pikachu that aren’t [male] or [female]. They alter our tails without our consent. But things are getting better. We are making change. We’re fighting so that our tails will be left alone.’ Under this is a panel showing the four Pikachu running happily towards the right. Text reads, ‘We’re all on a spectrum. Every tail looks different; anything is possible.’

The final text reads, ‘This is a comic about intersex people.’ The watermark in the lower right says @ PostManic. \End descriptions
