The [average American attention span has fallen](https://www.apa.org/news/podcasts/speaking-of-psychology/attention-spans) from 150 seconds in 2004 to 75 seconds in 2012 to 47 seconds in 2023 - a 5-6% annual rate of decline.

| Year | Avg American Attention Span (sec) | CAGR | 
|------|-------------------------------------------:| ---: |
| 2004 | 150                                      | -  | 
| 2012 | 75                                       | -6% |  
| 2023 | 47                                      | -5%  | 

How does this compare to these blog posts? 

In 2013, the average reader [dwelled on this site for 47 seconds.](https://tomtunguz.com/this-message-will-destruct-in-48-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. 

| Metric | Annual CAGR | 
| --- | ---: | 
| Attention Span Change | -5% |
| Blog Dwell Time Change | -4% | 
| Word Count Change  | -4% | 

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.    

Who said poetry is dead?
