Music Manipulation
A market in England displayed French and German wine. They alternated playing French and German music. With French music on, they sold 40 bottles of French wine and 8 German. With German music playing, they sold 22 bottles of German and 12 French. Surveys revealed shoppers had no idea of the influence the music had on them. (Tom Stafford in “Music, Wine, and Will.)
What does that say? Well, lots. But it definitely means that if you’re playing music in the background, it’s more important / meaningful / powerful than you realize.
And if you’re not playing music, that also may have more of an impact that you realize.
