Honestly you shouldn't require psychological science lessons just to successfully have business (Or non business related) meetings. This is one of the negative impacts from this technological age. What I mean by that is our continued reliance not just on utilizing these technologies constantly for information requests, but utilizing them for social interaction (Like social media sites) plus text messaging basically creates a world where there is almost no real need to meet people in real life.
Kids who grow up in the world today have almost no real social skills that can be applied in real life due to spending so much time either gaming or communicating with others on social media platforms, or better yet, communicating with others on their online games. These kids grow up and get jobs and have no ability to cope with constructive criticism and especially not some formal meeting where their livelihood and financial situation can hinge on the results of said meetings.
I feel like perhaps everyone needs to just take the time to occasionally either disconnect from it all, or go out of their way to spend real time with other humans. Otherwise articles like the one above where people require extensive psychological training just to meet with other people is going to become more common.
