So, Facebook has added “questions” in a new format. I’d like to warn everybody that Facebook makes vast cash from categorizing users… using technologies developed in Marketing theory. A particularly devastating aspect of this is referred to as “Psychographic Profiling”.

Those seemingly ‘friendly’ questions that Facebook is now baiting you to answer actually produce effective psychographic profiling data. If you don’t care if you’re profiled, answer away. But be aware that the real purpose isn’t to help people get to know you better. It’s to help machines determine what you can be sold and how to more directly manipulate your mind.

Because social media is at present largely toxic, it is damaging our minds and lives. Be aware of the actual motivations of cute-seeming bait that grants your social network structure to apps that use or sell it for nefarious purposes. And ignore this new “getting to know you” bait from your enemies at Facebook.
