"The difficulty with marketplace investigate is that people do not regard how they feel, they do not say what they regard and they do not do what they say."
So mentioned the late promotion enclose David Ogilvy, and his difference obtain to the heart of what is still a of the greatest challenges in business: How can you discuss it if people unequivocally similar to what you are perplexing to sell them?
Technology offers an answer to the subject that Ogilvy, who died in 1999, probably never envisaged.
Market researchers are already experimenting with desktop and smartphone applications that guarantee to exhibit the subliminal layers of a consumer's brain.
What's more, since this technology can work automatically and in real-time, it could potentially be used to weigh the romantic responses of millions of people before any product is released.
And, with a tiny caveat, this power could renovate marketplace investigate and truly the entire world of business forever.
(Oh yes, the "small caveat": to go along with this, you must be ready to believe that computers can interpret the intricacies of human emotion.)
Market disaster
Old-fashioned marketplace investigate is candid and unemotional: you obtain a representation of product testers and inquire them what they regard of a specific concept, product or brand.
But surveys and concentration groups pretence that people know what is going on inside their own heads - and that is a dangerous assumption.
"80% of new products brought to marketplace fail, mostly due to failures in normal techniques", says Rob Stevens, co-founder of UK marketplace investigate firm Bunnyfoot.
"I can't regard of any other area of business where such a disaster rate would be deliberate acceptable, nonetheless somehow, in marketplace research, it is."
Lie to me
Mr Stevens likes to explain his firm as a real-life chronicle of The Lightman Group - the illusory group in the TV array Lie to me starring Tim Roth.
Like Roth's character, Bunnyfoot's staff are lerned to mark clues in the facial expressions of product testers, that misuse their middle feelings - a routine well known as "facial coding".
They moreover use eye-tracking technology to guard precisely where a person looks during a product test.
Though comparatively aged and low-tech (facial coding goes back to Charles Darwin), these techniques are able of agreeable business insights.
"When you inquire a product tester if they speckled a specific underline on a webpage, they frequently discuss it you they did," says Mark Batty of online wardrobe tradesman Boden.
"But when you look at the eye-tracking, you uncover that they never saw it all."
Boden is in the middle of a usability study of its website, and as its e-commerce manager, Mark Batty has schooled not to put ample conviction in testers' pithy responses.
"Often their outcome of the entire site depends on whatever charge they did at the finish of the test," he adds.
"If they enjoyed the last charge they would be full of commendation about the site, even if their facial expressions suggested that they had struggled with it at the beginning."
Look in to my phone
The complaint with handbook techniques similar to facial coding is that they require a assistant professor to lay by hours of slow suit video, logging every mind-numbing scowl and every monotonous transformation of the pupils.
This means that studies are indispensably paltry to a tiny representation of testers.
Boden's usability study, for example, had a representation of only 30 people opposite 3 countries.
But this barrier could shortly be removed, by permitting computers to do many of the donkey work.
"Facial expressions may be read by a P.C. - it's only the transformation of pixels in a square of video," says Dr Roberto Valenti of the University of Amsterdam.
Dr Valenti and his coworker Dr Theo Gevers are so assured of computerised tension approval that they set up a offshoot firm called ThirdSight to money in on it.
"A assistant professor gets tired, they must be paid, they must be trained."
"But the program never gets sleepy and it can break down into parts thousands and thousands of faces at the same time."
ThirdSight's ultimate success is to obtain automatic facial coding program running on a smartphone, using the phone's inbuilt camera to record a product tester's expressions.
Machine learning
Of course, all of this hinges on the accurateness of the software.
And so far, Thirdsight's claims of accurateness are comparatively humble.
They admit that you still need a human assistant professor to manage the software, since it is unaware to context or dark meanings - it will provide both a cheerful grin and a baffled grin as "positive".
But other scientists are reduction conservative.
"We can routinely discuss it between not similar emotions with flattering high accuracy," says Professor Peter Robinson of the Computer Laboratory at Cambridge University.
"Our computers can obtain an accurateness of two-thirds or improved - that is about together with many people can do it."
Prof Robinson's team is perplexing to giveaway up tension approval program from elementary rules, such as grin = happy.
Instead, they're programming it to digest many variety of human countenance - facial and eye movements, palm and body gestures, the tinge of the voice.
Through a technique called "statistical appurtenance learning", the program then trains itself to recognize that indicators are critical and that are not.
If this type of power and accurateness could be incorporated in to a ThirdSight-style smartphone or internet app, then potentially millions of people's emotions could be fairly decoded.
"If you do an examination on Facebook, you've got half a billion people in your sample," says Prof Robinson.
"That means the census data turn rsther than bizarre, actually, since you are sampling roughly an entire race to obtain a result."
So, conceptually at least, the day may advance when no product is cursed to disappointment - since businesses will have access to roughly full certainty about their market.
