If you think people under 25 shouldn't make important decisions or be held responsible for things because their brains aren't fully functional “according to science”… I've got bad news for you

Counterpoint: No, there isn't

But sure, let's randomly assign incredibly loaded clinical diagnoses onto individuals who may have many valid reasons for not wanting to engage in-person with people, particularly ones who make damning evidence-free judgements of others and share them in a newspaper

Here's how gambling can change your brain

Why is gambling such a problematic addiction, when it doesn't involve any chemical intake?

I explain this, and more, for BBC Science Focus Magazine

The only 'Blue Monday' article you'll ever need

It's #BlueMonday again. And this is all you'll ever need to read to know the 'truth' about it

Which is that it's a ridiculous marketing stunt that got way out of hand and impacted me more than most people

Having my snarky writing efforts earn the public approval of ACTUAL BLOODY IRVINE 'AUTHOR OF TRAINSPOTTING' WELSH is *not* how I saw today going...

Even if i didn't think it was BS, I'm not being lectured on 'masculinity' by a sentient toilet brush that got rich by inventing online stalking

FWIW, a teen/adolescent may not have a 'fully mature' brain (insofar as that means anything) but that does NOT mean they have an 'unfinished' or 'deficient' brain

It's like how a 25m tall Giant Redwood is technically only "half" grown, but only an utter fool would say "that's not a proper tree!"

Is doom scrolling really rotting our brains? The evidence is getting harder to ignore

Many have asked for my take on this. So, is it another example of "I have concluded that my gut feelings are correct and I'm cherry picking 'evidence' to support it"?

Yes, yes it is
1/21

Article starts by citing one, ONE, artefact of modern online culture (Skibidi Toilet) as irrefutable evidence that human intellect is in terminal decline.

Because before the internet and smartphones, wider culture never once embraced anything objectively *dumb*. Not once.

*cough*
2/21

Apropos of nothing, consider the 'pet rock'. A very popular 'toy' of the 1970s, with an enduring cultural legacy, as so many people bought it the 'inventor' became a millionaire

Unlike Skibidi Toilet, people had to LEAVE THE HOUSE AND PAY MONEY TO EXPERIENCE THIS.
3/21

If you asked me to say which behaviour was the greater sign of low intellect, "Looking at a surreal animation for 11 seconds" or "Investing time and money into owning a rock", I'd have to go with the latter.

But that happened pre-internet, so it's apparently enlightenment-level cognition.
4/21

Then there's this point. I should flag up that few people are aware of "technology is literally rotting our brains, and compulsive internet use is destroying our grey matter", because that isn't happening.

5/21

Translation: when you increase the cognitive load a person has to deal with (as emails did), they have fewer cognitive resources to go around, even when compared to having just consumed a relaxing drug! Woah, mind blown!

Snark aside, there are some WILD extrapolations going on here.
6/21

Also, based on little information I can find about this 'study' (which isn't linked to, conveniently), it's based on a self-reported survey. Not sure how they arrived at 'a 10 point drop in IQ' from the information that provided. If IQ were even a useful metric here. Which it likely isn't.
7/21

I won't go into all the studies cited here, but the main point is this

Even leaving aside the small sample sizes and ambiguities, NONE of them shows any conclusive evidence that internet and phone use CAUSES changes/loss in brain structure or substance.

As ever "correlation =/= causation"
8/21

A more logical explanation is that "those who have alternative brain structures or deficits are more likely to show 'problematic' device/internet use, as they depend on it more, or are less able to regulate online behaviour etc."

Which is a whole other thing. And not necessarily a bad one.
9/21

The article is clearly convinced otherwise. I suspect the reporter has read the studies saying that problematic internet use is linked to *reduced* grey matter, or similar, and hasn't realised it means reduced *when compared to typical brains*, not *since the person started using the internet*
10/21

When you think about it, it's incredibly difficult to determine how an *individual* brain is affected by internet use etc. Because you'd have to do detailed scans of their brains BEFORE AND AFTER they developed problematic use. And how would you know in advance?
