You changed the way you kissed me - what can data really tell us?

Loving listing to the Example this morning - 'Changed The Way You Kiss Me' (Official Video)

But it makes me think…. I have this idea that your digital footprint (data) can tell me everything about you (and me), well eventually.  If all your yummy digital data is captured and we have the algorithm it could predict what is going on and even what will happen. 

So this song raises an interesting question; When you Change The Way You Kiss someone – did you know, do they know, does the matrix know or was I able to predict it? 

Behavioural economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we're not as rational as we think when we make decisions and therefore maybe we can – but does this idea take away some aspect of us being human?
