Advertising adds value to a product by changing our perception, rather than the product itself. Rory Sutherland makes the daring assertion that a change in perceived value can be just as satisfying as what we consider “real” value -- and his conclusion has interesting consequences for how we look at life.

That video was recorded in 19th July 2009, translated into 32 languages and has 3ml displays. It is called 'Life lessons from an ad man' by Rory Sutherland. 

Rory Sutherland stands at the center of an advertising revolution in brand identities, designing cutting-edge, interactive campaigns that blur the line between ad and entertainment.

The main idea which he was talking about is how to use marketings hooks also he is kinda ironic. He said that the point of education didn't actually work by teaching you things. It actually works by giving you the impression that you've had a very good education, which gives you an insane sense of unwarranted self-confidence, which then makes you very successful in future life.  

The funniest thing that breakfast cereals are main example. How possible is to do something really silly and convince society to their rights. They did nothing actually, they just said that square cereals now are diamonds. How it is possible that people have started prefer the new products, still the same in reality. It is called strength of belief.
