Rather than calling it human behavior and psychology I prefer to call it human weakness.

Human weakness, bias, ignorance etc are like software bugs in systems that mostly can't be patched.

We have got so good at detecting and exploiting these bugs at speed and scale that all I see happening is another Greenspan type moment, where a future Google\Facebook CEO is sitting before a committee wondering how everything imploded.

I mean Google\Facebook\Twitter etc benefit from the traffic Porn, Trump and ISIS pay for and generate much more than anyone else does. It's ridiculous.
