You can use these technologies to control the minds of your people and alien rivals, as long as they're not wearing tin foil hats.  The improvements give some big bonuses to influence and cultural resistance, and there's a trade good that increases Diplomacy by 50%.

You must have evil alignment to research these techs (Demonic alignment for some of them).

Put both of these files in your Mods\Data folder and you're ready to go.
