The average American attention span has fallen from 150 seconds in 2004 to 75 seconds in 2012 to 47 seconds in 2023 – a 5-6% annual rate of decline.

How does this compare to these blog posts?
In 2013, the average reader dwelled on this site for 47 seconds.
Today, it’s 33 seconds, a 3.6% decline – which is a bit better ! but probably within the realm of statistical noise ¡

Over the past decade, the average word count per post on this site has fallen 40% from approximately 560 at the peak to approximately 350 today.

So the deflation is consistent. We could argue the posts themselves are shorter, which reduces dwell time – but it’s the other way around.
Content on the internet has compressed : YouTube shorts & tweets come to mind. They provide a faster time to value/dopamine. Authors, rewarded for shorter content, mirror the rest of the web.
So, in ten years, when I update this data, expect it to be in a haiku like this one:

Attention span drops,
From one fifty to forty-seven,
Web’s brief dance evolves.

In the realm of blogs,
Seconds tick from forty-seven,
To thirty-three, soft fall.

Words on screen shrink too,
From five-sixty to three-fifty,
Echoes of the quick pulse.
