Your Kids Aren't Lazy; They're Just Smarter Than You

There's a recurring theme in the media, and in conversations with members of older generations, and it goes something like this:

"Kids these days have no concentration span. They're always Twittering or texting or instant messaging, and they're always playing these loud, flashy computer games instead of settling down to listen to the radio or read a good book. Computer games and the internet are ruining our kids minds! Won't someone think of the children?"

Oddly enough, these criticisms are often associated with complaints that "kids will spend all hours of the day on the bloody internet or playing these damned games, instead of going outside and climbing trees or riding their bikes", although nobody seems to see the inherent contradiction there.

In a nutshell it's this: surely if these kids really had poor attention spans they'd get bored of the game in short order and move onto something else? And if they lacked the ability for delayed gratification how would they manage to spend hours unlocking every achievement in Soul Calibur or grinding for loot on World of Warcraft?

I've been thinking for a while that much of the perceived "reduction in attention span" is merely kids getting bored with an activity that has inadequate input bandwidth to satisfy them.

For example, my grandparents could sit and listen to the radio with their eyes shut for hours on end, but the pathetically slow drip... drip... drip of information through the radio would rapidly drive me to distraction. Even my parents have trouble doing this - they usually listen to the radio while also doing other things, like household chores or driving.

Likewise, my parents can sit and watch TV for hours on end, but even this eventually bores me - being forced into passively watching and waiting for programmes to get to the point or adverts to finish leaves my brain with too much spare capacity - I either start to over-analyse the content of the show and get annoyed by the perceived agenda, or I start to get fidgety and end up picking up a book or going and doing something more engaging.

Conversely I can browse the web, program or play computer games for hours on end, and observation of most younger people will bear out that this is the norm, rather than the exception. The problem here is clearly not attention-span, or I'd rapidly get bored of surfing or gaming just as I get bored of the radio or TV.

The problem here is that with radio and TV the rate information comes to me is slower, and is determined by an external source - the broadcaster.

Conversely, when I'm playing a game or surfing the web the information-flow is limited only by my ability to absorb it. Result: my attention is fully engaged, I don't get fidgety or bored, and I'm happy indefinitely.

Books are another telling case: personally I love reading, and most "short attention span" kids I know who have a good reading-speed can still sit and read books (surely the least instantly-gratifying and most boring-looking of all media) indefinitely. Their reading-speed matches or exceeds their information-absorption rate, so they're happy.

On the other hand, even "normal" kids I know who have a slow reading-speed get bored and restless after only minutes of reading - even though their information-absorption rate is low, it's still higher than their reading-speed can provide, so they get bored.

I've noticed this in my grandparents, parents and myself, and I'm just past 30. I'd be frankly gob-smacked if this didn't apply to kids who'd only grown up in a world of globally-networked computers, millions of channels, the web at their fingertips and ever-increasing amounts of data to sift through.

It also raises questions about the sudden and questionable upsurge in diagnoses of low-grade ADHD and related disorders in young people over the last few years. Although in the more serious cases these are undoubtedly very real disorders, it's entirely possible that at the lower end much of what the older generation (and psycho-pharmaceuticals industry) perceive as pathological behaviour is simply plain old frustrated boredom in minds adapted to faster and better information-processing than they're capable of.

In summary, I suspect this phenomenon has little to do with "short attention spans", and everything to do with old media (still largely aimed at the older generations) appearing frustratingly slow and boring to ever-more-agile minds raised in our ever-more-information-rich society.

If this is true, this phenomenon could actually be a good thing - our brains are getting faster and better at information-processing, so things which seemed fun to our slower, less-capable ancestors now seem un-stimulating, or no better than momentary diversions.

However, generations who found crocheting or games of "tag" or charades the most amazingly fun experience in their lives now have to watch kids try their cherished childhood hobbies before discarding them as boring, trivial or simplistic.

It's therefore understandable that they find it a lot more comforting to automatically decide there's something wrong with kids today (a refrain that echoes down through the generations)... rather than realise that their own brains are by comparison so poor at information-processing that activities that were stimulating to them as children are just too simple for kids these days.

What's wrong with TV?

Why do people who watch TV typically watch so much of it, and why do people who stop watching TV do so? And why do people who don't watch TV often instinctively have such a poor opinion of it? After all, they usually used to watch it too, didn't they?

For the purpose of explaining my theory, I'm going to start with the conclusion I reached and work back from there there:

People dislike TV because it's an inherently sensationalist, emotive and passive medium. It positively discourages critical thought and subtly but definitely encourages a receptive, passive, uncritical mindset.

Constrained input frequency

Television drip-feeds you information without any activity on your part - indeed, you're better off not moving or doing anything else, as any activity on your part will only distract from the medium. Unlike reading (where you can read as fast as you feel comfortable), the speed of information-flow is limited by the television. This encourages a passive, receptive mindset, as there's literally nothing you can do to affect the incoming information flow without degrading it (e.g., by fast-forwarding).

Water, water everywhere...

The (often largely irrelevant) moving visual image also means that though there's a lot of information to take in at any one time, precious little of this is useful data.

Compare the amount of time and raw information in the written sentence

"The man walked twenty metres down the road."

compared with a video imparting exactly the same thing. Also compare the amount of useful, important data in the written sentence versus the sheer volume of unimportant information you have to assimilate from a video to get the same amount of data[1].

Nevertheless, with TV you still have to sift through all this unimportant information to select out the important parts, and this extra cognitive workload impairs and discourages any other thoughts you may be having. Additionally, having to handle such a comparatively large amount of input in real-time at least reduces the amount of attention you have to consider, analyse and critically evaluate what you're receiving.

Compared to other media

Reading, in contrast, is like accessing pre-filtered meaning - very little written text doesn't relate data essential to the communication, and text which does break this rule quickly becomes dull, windy and boring. Text is low-bandwidth (lower even than radio) and isn't inherently interesting to look at, so since the form won't hold your interest the content is required to be more interesting. Written text typically has a higher ratio of data-to-information - analogous to the idea of the signal:noise ratio in electronics.

Likewise, while radio has many of the same faults as TV (no random access, constrained input frequency) its lower bandwidth (audio compared to video) also communicates meaning much more efficiently than television - again, it has a higher data:information ratio.

Poor at communicating meaning

TV therefore communicates surprisingly inefficiently, in terms of the amount of raw information you have to sift through to extract meaning. This means that while it typically requires a large amount of attention to parse out the incoming information, it imparts relatively little actual data or knowledge... and what data it does impart is drip-fed to you at a rate much slower than you could typically assimilate it if it were presented in a more condensed or refined form.

Finally, its imposed (and slow) rhythm, high-bandwidth but data-poor input and a complete lack of interactivity (indeed, a disincentive to any activity at all) means no matter what you're watching, the medium itself acts to cultivate a more passive, receptive and uncritical mindset than you would otherwise experience.

Don't get me wrong - obviously there are plenty of situations where information could only sensibly be transmitted in a video medium (sports events, any communication where movement and visual change over time are important aspects, etc), and in any one particular instance these effects are typically very small[2]. However, when you compare the very nature of the medium of TV to other media (books, the web... arguably even computer games) it's hard not to come to the conclusion that it's the least interactive, least efficient and most unchallenging of all the mainstream media we typically use.


Footnotes

[1] Finally, if any extra detail is required or desired by the receiver (What man? How old was he? Was he wearing a hat? What colour?), compare the amount of mental exercise required be the receiver to imagine all these things compared to merely observing them.

[2] But the rather more worrying question is: are they cumulative? If one gets used to regularly existing in a passive, receptive, uncritical mindset does that make it easier (and more common) to to experience it in future? Obviously I'm not trying to claim TV turns people into mooing idiots or anything so excessive... nevertheless, at the very least it raises interesting questions...
