I think the rise of lies has little to do with humans being hardwired to resolve questions using emotions over reason. We prefer lies because we want a complex world to be simple, predictable, and manageable. Obviously it's not, so the only way that powerless people can believe their lives aren't spinning out of control is for authority figures to tell them what they want to hear: 1) every problem is simple and 2) a simplistic solution will fix any problem and return their world to the perfect Eden they believe it can and should be.
Happy fantasies are sustained only by lies. That's why we prefer lies.
