To be honest, most of these are surface level traits of an individual. There are deeper traits which go much more personal, and have even been touched on in popular culture in recent times, like in the new James Bond movie (think gait recognition). But even gait, although highly individual, is still touching the surface. I was thinking of &#x27;trimming the bloom filter&#x27; to such a degree that we can recognize not only a person on sight, but by cue words, and individual dictionaries alone.<p>It is no secret that our world is divided by language alone, so then as analysts we can attach certain words to certain behaviors, and this has been proven countless times to expose a person. If I speak English I probably respond in the same way to &#x27;pizza&#x27;. Pizza means food, and therefore pizza emotes a pleasure response. But &#x27;bomb&#x27; and other words must decide a different response then?<p>Marketers have copped this early on and frequently use talismanic phrases to elicit positive responses to products, so why not Facebook, and any other tech harvester of data such as Google, et al? Last time I checked it is not a crime to elicit responses using personal, and individualized key-phrases.
