Why we don’t understand as much as we think we do

I tried the ted miro player today and this is the first talk I watched. As usual I was inspired. The concept here is about teaching people properly by getting the message right. As fascinating a talk as it is obvious. the speaker is Johnathan Drori. Watch it then see how it changes your perception.
