Whatsapp forwards are in their own universe. Some of them are totally bizzarre, but some are half right with a twist given to them that makes them dangerous. Most of the so-called scientific forwards use enough jargon to make them sound real. People believe them and children are going to grow up learning science from Whatsapp forwards.
The more dangerous ones are of course the hate messages, rumours etc.

experts

After listening to many people talk in recent times, I have come to one conclusion.

I am a Chemist. It took me many years of hard work to acquire a moderate level of proficiency in Chemistry. Therefore, I am very sure I am not proficient in Mathematics since I have not put in any work in that area. I would straight away refer to a mathematician if I ever needed to solve a mathematical problem in any of my endeavours. Similarly for Biology or Economics or any other field.
But people who have not put in that kind of work in any one area, feel that experts are just people who talk a lot and do not know much more than they themselves do. They feel they can be as proficient as the experts in any field they care to think about. We get people who think they are environmentalists, economists, historians ....They truly believe they have the expertise. This is because they do not know how the real experts have acquired their expertise; how much work they had to do in order to acquire it.
It is quite fine when this attitude is limited to shouting at Sachin Tendulkar in the TV on how he should have hit that last delivery, but not when it come to serious matters that impact other's lives.
