Begin with Jesus Christ Superstar (about 45 seconds in) to get the concept and the groove.

Buzz is a new name for an old concept called word of mouth. When people you know say something to you about another product, service, person, event, issue, and on and on, that is word of mouth or buzz. It is an interpersonal, face to face persuasive message delivered without obvious benefit to the source.
If you read the scientific research literature of the pop press, most notably the NYT, Malcolm Gladwell or other such FauxItAlls, you know that Buzz is a preferred Cool Table Nudge, the gentle push behind your friend’s voice cooing in your ear, “ooohh, iGizmo, baby.” Thus, the Cool Table guys never talk to new potential customers, converts, or suckers, but rather the Cool Table Nudges Buzzers who will then talk to you. Hollywood shows this in those conspiracy movies that feature a CIA agent overthrowing a government. Hey, you don’t actually man the tank yourself, you just tell someone else who then tells another someone else and voila, you’ve got a revolution and another bad Matt Damon movie.
There’s no doubt that when a lot of people are Buzzing, there’s a lot of change in the neighborhood. But, is this Buzz truly causal and persuasive or is it merely correlative and not? It’s possible that after people have actually changed due to some other persuasive cause, they then start Buzzing and if you don’t know about that earlier and genuine persuasive cause, you’ve just fooled yourself on Buzz.
Now, here’s a novel idea: Let’s start with the real research literature rather than the latest pseudoscience from guys trying to sell ads. Get to a good social science search engine like PsychNet or EbscoHost and search on key terms like “wom” or “word of mouth” or “buzz” and see what you get.
My search turned up 100 hits for the various combinations of search terms going back to 1983. When you tighten your focus to publications that are “quantitative” and “peer review” the number drops to around 50. There are only a couple of “review” or “meta analysis” publications. (Here’s a pdf of the meta for you gear heads: WOM Meta) Now, 100 references over nearly 30 years is not much work. Over the same time period there are over 400 hits for “elaboration likelihood model” as a comparison. “Cognitive dissonance” turns up over 2,500 hits. “Credibility” delivers over 5,000 hits. There’s actually not that much good scientific information out there compared to other persuasion concepts.
What else is interesting is that most of the “wom” hits are in the last 10 years. Why? I’d guess we’re seeing the Cool Table at work here and that simply because we have networked computers, it’s just a lot easier to do a WOM study. Back in the day, you’d have to have a lot of confederates buzzing which takes time and money. Today you can buzz on a computer. Of course, one might ask if WOM is different when it arrives in the form of an email versus an actual person actually talking to you, but apparently that distinction is unimportant to the Cool Table. Buzz is Buzz even when it is mediated . . . if you sit at the Cool Table . . . otherwise?
Now, as I scan the various WOM studies one factor screams at me. Buzz functions differently across the studies. Sure, they all feature people talking to people about something else – the basic element of the Buzz – but what that Buzz accomplishes varies across studies.
This is not surprising if you’ve read modern persuasion theory. Any persuasion variable can function in a variety of ways. For example, across the Cascade, Buzz can affect Reception, Processing, or Response. Within the dual process models like the ELM or HSM, any persuasion variable can function as a WATTage switch, an Argument, or a Cue. Let’s consider Buzz in the many facets.
1. Buzz with Argument. The content of any buzz can contain information that bears directly on the central merits of the attitude object in question, whether a person, event, product, yada-yada. If the information in the Buzz is favorable we call it a strong Argument. If it is unfavorable, we call it a weak Argument. When people tell us this crucial information we are directly exposed to Argument quality and if we are High WATT, we engage that Long Conversation in the Head and Elaborate our thoughts to the Argument and change our attitude accordingly moving along the Central Route to create resistant, persistent, and predictive change.
2. Buzz as Cue. If we are Low WATT when we get the Buzz, we won’t engage that costly Central Route process, but we can make a simple Cue: If Other People Are Doing It, You Should, Too. Thus, through Comparison, we can create change as we hear people Buzz and follow the crowd. It helps, too, if we have affection for the Buzzer; we then get the Liking Cue piggybacking along with Comparison. Of course, this Peripheral Route change is less resistant, persistent, and predictive than the Central Route, but in the short term, it is real change.
3. Buzz as WATTage switch. “Gee whiz, this is the second time today one of my buddies has Buzzed on the New New Thing. I’d better look into this!” You don’t actually pay that much heed to the Arguments you hear and you’re not Cue-ing along the Peripheral Route, but at your earliest opportunity, you seek out your own information on the New New Thing and change accordingly. The Buzz flips the switch on your willingness and ability to think and motivates your drive on the Central Route.
4. Buzz as Reception. In the Cascade, the first step to ultimate downstream behavior change is Reception or just getting the message. Buzz thus becomes a form of advertising that appears all around you giving you opportunities to realize that there’s a New New Thing out there. No Arguments, Cues, or Switches, just pure awareness of the New New Thing. Thus, Buzz can break through the clutter and noise and make your New New Thing stand out as worthy of further attention.
5. Buzz as Response. Simply because people are Buzzing, some folks will form a positive response based not on the Cue, the Switch, or even the Arguments in the Buzz, but just from the pure presence of Buzz. Those are the Cool Table folks who value Buzz for itself and will hook onto the New New Thing merely because it is new. Thus, Buzz attracts like minded souls who dress, drive, read, eat, sleep, reproduce, and think like the Cool Table.
6. Buzz as Nothing But Chatter. You should never overlook the possibility that all that chatter is not Buzz, but just chatter, just people talking to while away the day with family, friends, and coworkers. It’s just the stuff of socializing, hanging out, killing time, just being there. Yeah, they used the New New Thing and they are talking about It, but more to talk with you than to talk about It. Not to be a Buzz Kill, but . . .
Now, when you realize how multi-functional Buzz is, it should dawn on you that a Buzz is not a Buzz is not a Buzz. It depends on how the Buzz functions if you want to understand how it works. Those self educated FauxItAlls at the Cool Table who don’t need no stinkin’ peer review science will simply see that Buzz can work, but will have no idea why it works in some instances, but not in others. They will focus on the mere fact of some success and groove on with it.
Instead, you’ve got a really good theory and you can think properly with it, so you realize that Buzz does work, but its effect will always depend on how you use it.
Finally, the practical part: How do you make Buzz?
Realize that Buzz is primarily Comparison or If Other People Are Doing It, You Should, Too. Typically Comparison is a Cue, except when the house is on fire, you don’t know it, and you see everyone else running, then Comparison is an Argument. Jokes aside, keep your eye on the persuasion ball. Buzz is Comparison.
The easiest way to generate Comparison is to buy people and pay them to Buzz. If you read the Comparison section in CLARCCS Cues, you’ll see many different ways to do this. My favorite goes back to a History of Theatre textbook about how play producers used to pay shills to hit the streets before a play and Buzz about it, then sit in the audience during performances and Buzz when the star entered and Buzz on the laugh lines and Buzz on the tear-jerker scenes and in general communicate positive Buzz on cue (nice irony there, huh, a Cue on cue.)
A nice variation on this strategy is to employ the Two Step Flow wherein you buy Buzzers who are Opinion Leaders in a targeted network. Those Opinion Leaders pour information into the network about your New New Thing creating a two step operation of You to Opinion Leader, then Opinion Leader to the Other Guys. (This is the basic process behind those large corporate type meetings where you assemble a bunch of fellow travelers on some topic, let them stand up in public and say cool things, then while serving them a fabulous lunch, you show them your New New Thing and how it connects to their Cool Table work. They then leave the room and Say It For You which means, Buzz, baby. This is why NIH will never suffer a budget cut. Take a lesson – some of those Feds are really dangerous people.)
Of course, the Buzz better front strong Arguments because once the Other Guy gets your New New Thing and discovers that it is cheap, lame, broken, stinky, rancid, expensive, and useless, your Buzz just bought you a customer base of Angst, Anger, and Hate. Buzz is one of those Be Careful What You Wish For admonitions.
Finally, don’t look to Steve Jobs and Apple as Buzz Mavens. They create desirable products that satisfy a large and rabid population. Jobs is shooting Buzz in a barrel because he’s got really strong Arguments with his iGizmos. Jobs may play some of the other tricks, too, but it all begins with those fabulous toys.
