How do they use bias to sell their products ?

Well, I'm not sure who's doing the selling but many companies will use a bias to sell their products. Think about commericals, you rarely, if ever, see negative feedback on the product itsself.  This is because they want people to buy the product BECAUSE someone else said it was great.
