Most fundamental changes in human societies happen due to technological advances.

The next big change in human psychology will come from inexpensive, very sensitive brain scans.

These scans will show millions people in real-time how their brains are actually behaving and reacting. Presently unnoticed or concealed twinges of emotion will become conspicuously visible on a screen or within a hologram that surrounds our heads.

People will be able to use this technology in the company of a computer program or with a human partner. A good AI program will use brain-scan information to reveal much about us. We will learn stuff about how we actually function that very few are aware of today.

Having this knowledge will change the way we understand ourselves and our interactions with others. Rather than work almost exclusively with the vague stories we tell ourselves, we will be able to see how our brains (and bodies) actually function in real time.

The difference between our stories and how we actually function is very great. Great enough to completely change the landscape of what we now think of as human psychology.

There already exist inexpensive EEG rigs that are sort of good at measuring moods and honesty. There are also expensive ones with more capacity. Within a decade or two, these devices will be much better. An accurate lie-detector will surely be included in the consumer package.

This technology will rewrite our understanding of human psychology and remake the ways we think of human society today. If you want to get a head start on the future, learn how to do FIML now.
