This New York Times article is selling ZMET for some reason, but it's definitely not unusual to blend psychology with marketing. All of the pros do it. Edward Bernays, the godfather of the PR industry, was Freud's nephew. He used his uncle's discoveries to help sell everything from World War I to cigarettes. I'm fascinated by Bernays because he's shaped much of our modern consumer culture but isn't widely recognized for doing so. And that's the way he wanted it.
Check out this somewhat eerie chapter about Bernays from the excellent book PR! by Stuart Ewen.
"The greatest thing a human soul ever does in this world is to see something, and tell what it saw in a plain way...To see clearly is poetry, prophecy, and religionall in one." - John Ruskin
