Signal
Once upon a time, Gutenberg invented the printing press. Books were expensive to produce and distribute, and literacy was a luxury only the privileged could afford. But the printing press started an inexorable trend. Since its invention in the 1400s, the technology for information distribution has progressed rapidly.
Newspapers, then radio, then television, the internet are major milestones on the path to the present. Information has become ubiquitous, available instantly to anyone who wants it.
When information was scarce, it was easier to absorb it, digest it, and make decisions regarding its importance and relevance. Now, we face an entirely different problem. The signal to noise ratio has eroded dramatically in the past decade, making it increasingly difficult to find information of value.
One problem is a shift in mainstream media away from news and towards entertainment. For example, a popular Calgary radio station has three celebrity gossip segments every weekday morning. I’d much rather hear a traffic report, local news, weather, or heck, maybe even some music, but this is what mainstream media provides.
Of course, they wouldn’t devote three segments during the peak morning listening hours if people didn’t want to listen. This is an interesting comment on our society by itself, but it has the effect of reducing the amount of airtime that can be given to a topic like local news.
The news has also gotten shallower. A typical story on the radio or television has been reduced to a couple of sound bites chosen for maximum impact / entertainment value rather than their value as information. Someone seeking more depth to a given story has to do a lot of digging to find it and frequently needs to look beyond mainstream media. I don’t know how many people make this effort.
A second problem is created by the rise of social networking sites like Twitter and Facebook. In and of themselves, they’re great ways to keep in touch with people and find out about events and news of interest, but there is an awful lot of noise there as well. Unfortunately, these sites only provide one really effective way to deal with the noise: ignoring someone entirely. This means you throw out some of the signal along with the noise.
I don’t think there’s an easy solution to this one – we’re already at the saturation point for information and the trend shows no signs of slowing down. I firmly believe that information availability is a good thing relative to the alternatives, but what do we do when such a large amount of the information available has so little value? What do we do when mainstream media does not provide an appropriate level of depth? How do we improve the signal to noise ratio?
