I'm glad you made the distinction in your subject line that the article's author does not: data, in itself, is not necessarily information, i.e. it doesn't necessarily inform us of anything. Some of it is totally useless, and more of it requires some astute analysis to turn it into actual information. Our brains on data are quite different than our brains on information. As I see it, this is one of the major roles of tech educators (as well as traditional school librarians): help kids to understand the difference and keep their sanity (or reasonable facsimile thereof).

Reclaim your brain
By Brian Wheeler
BBC News Online Magazine
More information has been produced and stored in the past five years,
than at any time in human history. E-mails, text messages, mobile phone
calls, TV, websites. We are drowning in the stuff. But how much of it
has added to the sum of human knowledge? And has anyone thought what it
is doing to our brains?
Researchers from the University of California estimate that 800MB of
new information is produced and stored each year for every member of
the human race.
What's in your 800MB?
92% is information stored on magnetic media. The vast
majority is held on computer hard drives as well as audio
and video tapes
7.75% is photographs and films
0.03% is on paper, including books, newspapers and magazines
- this has increased by 36% since 1999, largely due to people
printing computer documents
0.001% Optical storage media such as CDs and DVDs
That is double the amount produced just three years ago - and is the
equivalent of two floppy disks per day for every man, woman and child
on the planet.
This massive explosion in information has arguably empowered millions,
transforming them from passive consumers of culture into active
participants in a 24 hour global debate.
But others claim that when the fog of new data has cleared we will be
left with very little in the way of new knowledge or understanding.
"I think you are going to see more rapid production of further
information," says Keith Kendrick, head of neuroscience at the Babraham
I don't think creativity will disappear entirely, but it has become a
world of expertise
"What you might not necessarily see is the answers to the really big
In science, Professor Kendrick says, the vast amounts of information
researchers now have to wade through means they are focusing on
ever-smaller areas of expertise.
As a result, there are fewer "big thinkers". It has become harder to
see the bigger picture, because it has simply become too big.
And, he argues, if your ideas are constantly reviewed against everyone
else's, there is arguably less room for idiosyncratic and original
"I don't think creativity will disappear entirely, but it has become a
world of expertise in a more limited field.
"The big thinkers who try to make sense of a whole area of science are
The marketing industry is often blamed for the increase in cultural
background noise and unwanted information.
Opinion is divided as to how many commercial messages a person is
exposed in a single day. Recent research in the US said it could be as
many as 2,500.
"We have absolutely no idea what this constant advertising babble is
doing to us," Kalle Lasn, founder of anti-commercial group Adbusters
"The situation is similar to what we were experiencing at the start of
the environmental movement 40 years ago, when people just didn't want
to believe that three parts per billion of some chemical in the air or
water could be toxic and have all kinds of unforeseen consequences down
"Today we are repeating that same mistake in our mental environment."
Adbusters, which is best known for its sophisticated spoofs, such as
its Joe Chemo - a swipe at Camel cigarettes - campaigns against what it
calls the "corporate colonisation of the mind".
It encourages "culture jamming", small acts of defiance against
encroaching commercialism, such as asking for the home phone number of
telesales callers or returning faxed or e-mailed ads to their senders.
Valuable brain space
The group also holds an annual Turn-off TV Week, although it claims a
15 second "uncommercial" for the event was rejected by most of the
country's television networks.
Other groups, such as Commercial Alert, are campaigning for a ban on
selling naming rights to public spaces and the commercialisation of
health care, education and culture.
But Professor Kendrick casts doubt on the idea that all the extra
information in the world is using up valuable brain space.
Apart from anything else, the brain does not necessarily have a finite
"The potential for the brain to memorise is enormous. No one wants to
put a final limit on it," he says.
The mind does not store information in a cold, clinical way like a
computer. Memory is strongly linked to emotion.
So although we are bombarded with information all the time, we are
unlikely to remember much of it.
The problem is not the amount of information you take in, but what
your brain does with it, Professor Kendrick says.
"Trying to take in lots of information and organising it in such a way
that you can bring it back in the right way, at the right time, is
quite a problem.
"We have got so much information now that you are likely to overload
your own personal capacity."
People have had to learn how to cut through the "noise", selecting
what is relevant and what is not.
"You have to be able to gloss over information extremely fast, instead
of dealing with everything in phenomenal detail."
The effort that used to be involved in researching a subject,
Professor Kendrick argues, meant strong emotions were associated with
it, making it stick in the mind.
"If you find it hard to get information it sticks. Before the internet
came along, just the achievement of finding out something was an
emotional euphoria all by itself."
It's a sobering thought. But will you remember it tomorrow?

There has been an enormous amount of information available for
centuries, increasing vastly in the last 150 years. Admittedly this has
not been in an electronic format but in the form of newsprint, books,
photographs, radio, TV. And up until now no one's brain has exploded as
we're well adapted to ignoring the huge amount of useless information
that we're surrounded by every day.

I can just see it, 50 years from now, emblazoned across the sky in
mile high lettering (Arial, 50,000,000 pt) "Today's sunset was brought
to you by BIGCORP plc and the weather was controlled by WEATHERCORP inc
- we hope you tune in to EARTH.COM tomorrow for some pleasant afternoon
sunshine followed by a light shower". I've recently ditched my mobile
phone in an effort to 'get away' from information overload - I don't
want to be contactable 24x7 and I certainly DON'T want mobile spam.
Simon Mills, UK
The massive increase of information we have to process is a problem.
However the real damage is being done to children who are growing up
pre-programmed into certain brands and ideals. Their information
filters are not as sophisticated as adults. We live in a time where
everything has a dollar sign attached to it by ad-men and marketing
consultants. We now spend so much time processing adverts and thinking
what we want, we are forgetting others.
How a brain that evolved on the plains of Africa copes with the
increasing sophistication of verbal and written perceptions of our
world has yet to be seen. Happiness indexes constantly show we are no
more happier than 50 years ago, so this data doesn't seem to be
improving our lives. We need to be taught how to filter this
information, using emotional tools to remember the stuff that really
matters, moral ways to live and the like, not what the recent 2 for 1
offer down the supermarket is.
Like stress, there is a good level information - that is, enough to
allow us to function proactively, make quick rational decisions, and
support a level of multi-tasking. Too much information is increasingly
detrimental to our effectiveness and a reactive or passive behaviour
results. I worry for my children who risk having their individuality
and creativity suppressed at an early age. I can still remember making
my own entertainment - for them a natural reaction to a lull in life
will be to turn-on whatever, log-in to something, switch into receive
The point that "Memory is strongly linked to emotion" is interesting -
advertisers know this and this is exactly why they increasingly resort
to shock tactics. They're competing to shriek above their own racket
like noisy schoolchildren. What possible good does all-pervading
"ambient" advertising do for society? If I want information, I'll get
it myself, thanks.
I think one of the most vital talents or skills a human being can have
in the modern world is being able to sift out what is important from
what is not from the sea of facts and figures we have before us. Can
this ability be taught? I think it can and that we should start
teaching it to kids now.
