Today’s invention is really just a simple extension of the idea of personal feedback on eBay.
Anyone who wanted to be involved, could equip themselves with a wifi device: effectively a badge working in peer-to-peer mode with a deliberately restricted range. When two people meet, or have any kind of interaction, either can choose to rate the various aspects of that exchange (there would be no way to block someone’s attempt to leave you feedback -once you decide to wear the badge, you would be committed to being judged by your peers). The rating would be multidimensional in order to allow people a chance to describe your behaviour, character, temperament and attitude.
The interface design would be crucial -probably consisting of twenty or so ‘sliders’ one for each dimension of the interactions. Feedback would have to be given when within the restricted wifi range, so I’d imagine that leaving a rating would have to be via some subtle tactile device hidden in a pocket or up a sleeve.
Updates to someone’s badge would would be visible to them only after the interaction, in order to minimise any conflicts but the source of the new rating would be indicated: anonymous peer review is evil.
If one person is constanty saying how nice a meeting with you was, then you might choose either to downgrade the score you give her for honesty or call her up for a date. Similarly, if lots of people seem to have the wrong idea about you, then this gives you a chance to think about the messages you are giving out and possibly modify your behaviour. Either way, maybe it offers an opportunity for decent folk to be both judged by their actions and easily identifiable.
People could thus gain a greater insight into others, if they were prepared to put their own true colours on show.
