In one of my tweets (see here), I referred to 'priming' and used the simpler Wikipedia definition. I had blogged about priming previously too: here.
Here's is another striking experiment I picked from Think Twice by Mauboussin ...
In this test, the researchers placed the French and German wine next to each other, along with small national flags. Over two weeks, the scientists alternated playing French accordion and German Bierkeller pieces and watched the results. When French music played, French wines represented 77 percent of the sales. When German music played, consumers selected German wines 73 percent of the time.
Amazing, isn't it?
I am assuming, the shoppers were able to make out French music from the German music.
If I were to carry out the experiment, I would do this experiment by alternating French, German and some distinctly non-German, non-French music, say Indian music. Just to see the impact on the sales when Indian music played out.
