Are we addicted to information? Is there something hardwired into our beings that makes us unable to resist compulsive Twittering? Every other day there's a news article or radio story on how studies show that... well, really, not much more than scientists like to publish things.
The Mind Hacks folks do a good job of demolishing the "studies show" myth with respect to information-seeking behaviour here. If you've ever nodded to one of those articles going on and on about how we're natural information addicts, then go read this one. Now. GOOGLE COMMANDS IT.
In case it's not obvious, I think those theories are, like a lot of the rest of pop psychology, bullshit. Yet we techie types eat them up like coffee ice cream or something. If you'll excuse me, I have some bark to examine now.
