There is this funny comedian named Anjelah Johnson, my wife and I really enjoy her shows. In one of her shows she mentions how she takes medical advice from anyone wearing scrubs. Scrubs are a type of overalls doctors and nurses wear however anyone can buy and wear scrubs some daycare teachers wear scrubs to daycare.
In 1916 Nathan Handwerker was looking for a way on Conney Island to sell his hot dogs. Nathan understood the respect that doctors garnered on Conney Island and used this to his company, Nathans Famous Hotdogs”, benefit. Nathan hired folks to eat his hotdogs while wearing white coats. Doctors and lab technicians wear these white lab coats quite often. Nathan never really made a statement that doctors endorsed his hotdogs but allowed everyone to assume it. Like scrubs, lab coats can be purchased by anyone. At a factory I used to work out the employees on the floor wore lab coats when they dealt with insulation.

It can be tempting to trust people that we believe have authority however how we authenticate this is very important. a uniform does not make someone an expert their actions and knowledge does though.
Sometimes it is ok to be like someone from the state of Missouri and ask someone to show you how and why they are an expert.
