This is just a haphazard sampling, but with an Effect Size this Stupendous, even a focus group will demonstrate it. Start with a recent article about the Obama re-election effort.
CHICAGO — With a “chief scientist” specializing in consumer behavior, an “analytics department” monitoring voter trends, and a squad of dozens huddled at computer screens editing video or writing code, the sprawling office complex inside One Prudential Plaza looks like a corporate research and development lab — Ping-Pong table and all.
Now, the popularity of hiring statisticians in business.
Arcane statistical analysis, the business of making sense of our growing data mountains, has become high tech’s hottest calling. There are billions of bytes generated daily, not just from the Internet but also from sciences like genetics and astronomy. Companies like Google and Facebook, as well as product marketers, risk analysts, spies, natural philosophers and gamblers are all scouring the info, desperate to find a new angle on what makes us and the world tick. Computing has become cheap and available enough to process any number of formulas.
Finally, a scientific breakthrough for data mining.
Are there subtle patterns lurking in data that can foretell of a coming financial-system crash? What can explain the variations in sports-star salaries? How about the complex relationship between genes and certain diseases? Scientists in various fields have been searching for better ways to analyze large piles of data for such patterns, but the difficulty has always been that they need to know what they’re looking for in order to find. A new software program, described in the latest issue of Science, is designed to find the patterns in data that scientists don’t know to look for.
You’ve read variations on the Big Numbers theme. There’s Truth in them thar Hills of Data and if you know how to Mine Them, you can Change the Other Guys, win elections, earn trillions, and sit at the Cool Table. Particularly among aspiring persuasion mavens, Big Numbers with Big Data and Big Statistics is the New New Thing. Since everyone is living in Web 2.0 everyone has torrents, tides, and tsunamis of information about Other Guys which has got to lead to Change. Right?
While there’s a ton of nuance in the answer to that question, the First Nuance for me is:
Numbers without Theory is just a million Monkeys at the Abacus.

Just as those monkeys at the typewriter won’t produce Shakespeare, neither will these monkeys at the abacus produce Fishbein and Aizen or Petty and Cacioppo or, to be more famous about it, Kahneman and Tversky. Yet, the New New Thing rush to Big Numbers pretends you can drop the theorist and as long as you have monkeys with degrees from Stanford or Carnegie Mellon armed with quantum computers, you can discover like Einstein.
You see my bias. I’m a theory guy and that reflects both my nature and nurture. Without a schematic, a blueprint, scribbles on a paper cocktail paper, you will not find Truth whether for elections, business, or science. Theory is the One Ring that binds all other Rings. And the better your Theory, the better everything else about your persuasion.
Sure, If You Can’t Count It, You Can’t Change It. But remember.
Just Because You Can Count It, Doesn’t Mean You Can Change It.
