Framing a debate can help you to get people to see an issue from a different point of view. Politicians are great framers. One of the reasons Republicans in the U.S. did well in the past was that they used the power of framing to get media and opinion leaders view an issue from their desired point of view. So 'global warming' was referred to as relatively harmless 'climate change'. 'Quantitative easing' was used to refer to something which was essentially the government electronically creating more money.
How you frame a discussion can also help you in persuading people and selling your ideas and products effectively. Good marketeers do it all the time. In the early 90s, The Ecomomic Times (a leading business daily in India) drastically reduced its cover price and called it 'Invitation Price'. Recent tourists visiting Egypt find savvy salesmen offering them 'Revolution Prices'. In both these cases, by not following the normal practice of using the term 'discounted price' or 'special price', they were able to make consumers give their products purchase consideration leading to purchase decisions. Thats the power of framing.
