Listen now (19 mins) | Sorry about the delay in sending this out. Humans are social creatures and we spend much of our lives perceiving, assessing and judging others. For example, most of us can easily recognize faces. But, surprisingly, some people struggle with it. These individuals are termed "Prosopagnosics" or "face blind." It's more common than we thought; about 1 in 50 people have this difficulty. On the other hand, some are exceptional at recognizing faces and are termed "super recognizers".
