I’ve been interested for the past few years in the inference that can be done using publicly available information. The web means that people nowadays give quite a bit of information away freely in their public profiles. There are now a number of tools which automatically attempt to link peoples user accounts together based on profile information provided and there is a lot of other information that is picked up through the routes and links that people click through and make determinations about the type of person, sometimes referred to as social graph privacy.
I found the article “Eight Friends Are Enough” from a group of researchers at Cambridge interesting because, using data provided from Facebook, it seems to support the claims that much can be inferred by the information provided by the person and by their peers (friends). I’ve seen various media articles using this research to make bigger claims for example there was an article in last week’s Sunday Times about how governments are using this type of information for political gain, removing dissident factions and controlling populations. Our own government for example is conspicuously scanning email traffic looking for terrorist threats.
It will be interesting to see how things pan out in the future. I already know that for example I have spent money buying things that were brought to my attention through services designed to target advertising to me based on my previous preferences. That’s a small and some would say innocuous example of how information is used. Humans are influenced by others, the ‘wisdom of crowds’ can sometimes mean that large numbers follow a direction because they see ‘trending’ on Twitter or highlighted on Facebook. Is this any different from reading it in print? – I think the difference is that if you think enough of your friends have liked something you may give it extra gravitas. So the more of the social network we engage in the more our individualism may get polluted? – Or perhaps it no different from going to the pub and agreeing with people just to keep them happy?
Certainly the web opens opportunities for social influence marketing, and consequently for other uses of that information.
Here’s an interesting video on YouTube by Nicholas Christakis: The hidden influence of social networks
Hmm. Ripples in the pond.
