Near the beginning of "The Hidden Persuaders" (1957), Vance Packard quoted  from Advertising Age magazine the first principle of the new science of  motivation research: "In very few instances do people really know what they  want, even when they say they do." Fifty years later, this astounding revelation  has begun to penetrate mainstream economic theory. Better late than  never.
 American political ideology since around 1980 can pretty much be summed up  in four words: markets good, government bad. Unregulated competition, in this  view, is optimally efficient; governments need only enforce contracts, tend to  national security, and then step out of the way. Neoclassical economics  demonstrates with mathematical elegance that, if not interfered with, supply and  demand, production and consumption, will glide smoothly toward a stable  equilibrium.
 But any proof is only as good as the assumptions it rests on. According to  conventional economics and political science, consumers and voters can be  counted on to make rational choices. "The assumption that we are rational,"  writes MIT economics professor Dan Ariely, "implies that in everyday life, we  compute the value of all the options we face and then follow the best possible  path." It also implies that we have sufficient information to make a wise  decision, and that the context in which we decide doesn't matter - deciders are  always calm and objective. It implies, as incoming Harvard law professor Cass  Sunstein and University of Chicago economist Richard Thaler put it, that we are  "Econs" rather than "Humans."
 We're not, of course, as wise humans (and wily advertisers) have always  known. A new sub-discipline called "behavioral economics" has begun to quantify  this perennial intuition and assess its implications. Two engaging, enlightening  new books divide these tasks. "Predictably Irrational" describes some of the  research leading economists to modify many standard assumptions. "Nudge" turns  these insights to account, suggesting improved strategies for individual  decision-making and public policy.
Kansas, Or A  Seattle Suburb?  At Mercer High School, two teachers -- Val Foubert and Jim Wichterman --  generated regular parental thunderstorms by teaching their students to challenge  societal norms and question all manner of authority.  Foubert, who died  recently, taught English.  His texts were cutting edge: "Atlas Shrugged,"  "The Organization Man," "The Hidden Persuaders," "1984" and the acerbic writings  of H.L. Mencken.
With  the right spin-meister the most rotten of us can smell like a  rose  R whistle-blower David Michie is an expert in corporate spin, having worked  in PR in London for more than a decade before writing The Invisible Persuaders,  an insider's account of how British spin doctors manipulate the media. When not  writing books, he still represents a few clients from his home in Perth. 
 
He too believes it's no longer possible for corporate players to get by  without the hottest spin doctor in town. "Without question the importance of  good marketing has increased dramatically. I don't know about celebrities, but  spin is particularly vital for companies, especially listed companies. Journos  wield enormous power, and have to be engaged with professionally. 
 
"High-level executives often lose objectivity about how a company is  perceived. If you don't have good taste, it's sensible to hire an interior  designer. Similarly, entrenched executives need to hire external communication  advisers." 
  U.S. advertisers spent nearly $500 per American last year. But what makes  one ad persuasive and another a dud? Two Bay Area firms have adapted brain  scanning technology to gain insight into the science of spending.
 
"We can't read your mind, I assure you," said A.K. Pradeep, chief  executive of NeuroFocus. But his Berkeley firm can do the next best thing - scan  your brain to map the electrochemical spikes thought to signify attention,  emotion and memory.
 
"This is the next generation in market research," said Hans Lee, chief  technology officer for EmSense Corp. The San Francisco startup also is using  electro encephalograph, or EEG, technology to correlate brain activity with  physiological cues such as skin temperature or eye movement to gauge how people  react to ads, computer games, even presidential candidates.
 
EmSense and NeuroFocus are leaders in neuro-marketing, a field that  aspires to create objective measures of the effectiveness of the $149 billion  that U.S. firms spent last year on advertising, according to TNS Media  Intelligence, to reach 300 million Americans.
 
UC Berkeley neuroscientist Robert Knight, a scientific adviser to  NeuroFocus, said neuro-marketing has arisen at the confluence of three trends: a  better understanding of the regions of the brain; precise sensors to measure  when, say, the memory center is active; and software to infer from these  telltale signs whether a given message resonated with men or women of different  ages.
 
"Neuroscience today is where physics was at the turn of the last  century," Knight said. "We've had the groundbreaking thoughts and theories. Now  we are measuring and testing."
 Science laid the foundation for neuro-marketing by studying conditions  such as attention deficit disorder, which taught researchers how to recognize  the electrical signals of alertness, and Alzheimer's disease, which required an  understanding of how we form memories. Such studies have revealed which areas of  the brain become active when we see a tiger leap across a screen or watch a baby  smile - signals captured using instruments such as sensitive EEGs.  
Mall  of the mind  Anderson quotes comedian Carl Reiner early in the first show: "A brilliant  mind in panic is a wonderful thing to see." And Anderson's job is that of  provocateur as much as announcer and facilitator. He is the punter surrounded by  the industry, asking the questions we would if we knew the tricks its new  psycho-persuaders like to pull these days. 
 
He understands that the unique contribution of TV to advertising is its  prodigious ability to communicate not simply information about a product but  also fantasies about consumers and how they choose to live. It's where so much  of his comedy comes from, after all.
