What's My Line?

In the 1950's there was a popular TV show in the US called "What's My Line?". The panel, composed of minor celebrities, would hear a brief description of the interest job or accomplishments of an otherwise little known person. then 3 individuals would appear, each claiming to be the person whose bio had just been read. The panelists would ask them questions for 10 minutes to try to determine which of the 3 was the real person and which 2 were imposters. The panelists would succeed about 2/3 of the time. The lesson for the real world is that we are not so good at detecting fraud as we might like to think. We are easily misled by appearances and our prejudices and preconceptions.
