OKCupid Founder Unleashes “Dataclysm”

Dataclysm by OkCupid found Christian Rudder

One of the founders of the dating site “OK Cupid” just released a new book — and it reveals some stunning insights about how people live today. (And Amazon’s discounting the Kindle edition to just $6.99.) After 10 years of running OKCupid, Christian Rudder has crunched the data to uncover some surprisingly clear patterns about what people really want. The title of his book? Dataclysm: Who We Are (When We Think No One’s Looking)

“Tonight, some thirty thousand couples will have their first date because of OkCupid,” Rudder writes in the book’s introduction. “Roughly three thousand of them will end up together long-term. Two hundred of those will get married, and many of them, of course, will have kids.” It seems like just one out of every 150 dates will end in marriage, I thought at first. But then I realized: that’s happening every night — so 73,000 marriages each year are beginning with OKCupid dates!

“There are children alive and pouting today,” jokes the site’s founder, “grouchy little humans refusing to put their shoes on right now, who would never have existed but for the whims of our HTML.” And Rudder used to maintain a blog on their dating site that was called “OKTrends” — interesting observations about what patterns they were observing — according to Wikipedia. Rudder only stopped writing the blog in order to collect the same kind of information into this book. And according to one reviewer at Amazon, “This book may be to Data Science…what Freakonomics was to Economics…”

So what did he learn? Rudder revealed one fascinating experiment in July. OKCupid tried blatantly lying about the compatability of online dates, telling customers they’d discovered someone who matched 90% of their dating criteria…when they’d actually only matched 30%. (And to test the opposite, OKCupid told some customers that they’d also found people matching a mere 30% of their criteria — when, secretly, those people were actually a 90% match!) The results? Users sent more messages –at least “a conversation” of four — when they believed there was compatibility. Their own interactions weren’t always enough to convince them to keep those conversations going….and they put more faith in the numbers from the web site!

And surprisingly, people were much more likely to take a chance on e-mailing a person when there were no pictures available to judge how attractive they were….

Christian Rudder graduated from Harvard with a degree in math, according to The New York Times, calling Rudder the “Unblushing Analyst of Attraction” for OKCupid. And there is a stunningly geeky frankness in the infographics he’s released in advance of the book. For example, Rudder reports that the most sexually-aggressive states in America are Montana, North Dakota, Oregon, Vermont, and Wyoming. Meanwhile, Ohio and New Hampshire are the states least interested in sex and most interested in finding love…

Of course, there’s also a startling confession in Rudder’s book. “I’ve never been on an online date in my life and neither have any of the other founders…” So he’s not trying to push people to their web site, “and if it’s not for you, believe me, I get that.

“Tech evangelism is one of my least favorite things!”

Amazon Discounts “Best Books of November”

Cover of Steve Jobs biography by Walter Isaacson

Amazon’s created another fun web page to “lure” customers into buying more new Kindle ebooks. They’ve announced their “Best Books of the Month” — their editors personal picks — which will all be available at a 40% discount for the whole month of November. And Amazon’s also found a fun new use for their “Amazon Books” page on Facebook. To attract interest in these newly-discounted books, they’ve also started posting “Great Sentences from our Best Books of November.”

So what’s on the list? Their “Spotlight Selection” is Steve Jobs, a new biography by Walter Isaacson (a former managing editor at Time magazine). It became Amazon’s #1 best-selling book the week
that Jobs died before it was even released (based on pre-order sales) — and it’s still Amazon’s #1 best-selling book. Now it’s available as a Kindle ebook for just $16.99 (though the print edition usually retails for $35.00) — and it’s received the ultimate review from my friend Wendy. She told me her three-year-old son requested that she read the biography to him as a bedtime story. “We mostly concentrated on the photos and captions,” she told me today, “but he fell asleep very quickly.” But it still made her geeky husband very proud.

Amazon’s also selected the best fiction books for November — including the first collection of short stories ever by author Don DeLillo. “From one of the greatest writers of our time…” Amazon explains in their product description, “written between 1979 and 2011, chronicling – and foretelling – three decades of American life.” In the title story, two nuns in the south Bronx see the ghost of a child named Esmerelda. And there’s also an intriguing story called “Human Moments in World War III,” where two orbiting astronauts start picking up an American radio broadcast — from 50 years ago!

The book is called The Angel Esmerelda, and it won’t be shipped until November 15th — a week from next Tuesday. But Amazon’s already begun sharing some quotes on Facebook. It must be fun to be the editor at Amazon who gets to decide which “great sentence” to share. They’ve chosen two from The Angel Esmerelda — though it’s not clear what story they’re from.


“Vollmer has never said a stupid thing in my presence. It is just his voice that is stupid, a grave and naked bass, a voice without inflection or breath.”

“He spoke of distances in meters and kilometers and it took me a while to understand that this was not an affectation so much as a driving need to convert units of measurement more or less instantaneously.”

And there’s quotes from other books on the Facebook page for “Amazon Books” — including this intriguing sentence from an exploration of American oddballs that’s called Pulphead.


“He had touched death, or death had touched him, but he seemed to find life no less interesting for having done so.”

But one true crime book actually came from long interviews with “mafia royalty” over three years — the man who helped the Medellin Cartel smuggled cocaine into America. “As Wright’s tape recorder whirred and Roberts unburdened himself of hundreds of jaw-dropping tales, it became clear that perhaps no one in history had broken so many laws with such willful abandon,” reads the book’s description on Amazon.
At one point the criminal “became so powerful that he attracted the attention of the Republican Party’s leadership, was wooed by them, and even was co-opted by the CIA for which he carried out its secret agenda.” The title of the book? American Desperado: My Life–From Mafia Soldier to Cocaine Cowboy to Secret Government Asset. And Amazon’s identified some of the books most tantalizing quotes which they’re sharing on Facebook.


“They say crime doesn’t pay. What a farce.”

“The Medellin cartel was beyond evil. They were like Walmart.”

There’s also a book by a Nobel Prize winner — Daniel Kahneman, who won the Economic Sciences award for challenging the rationality of decision-making, and has finally collected his thoughts together
into a single book. He identifies “fast” thinking — our intuitive emotional responses, which have extraordinary power, but which also influences our more logical “slow” thinking. The book’s title is Thinking, Fast and Slow — and it’s hard to resist the idea of a book which could challenge the way we view our own thoughts!

I remember an aging author who once said we like to read because, just for that moment, there’s an order and a pattern to our experiences, giving a clear “dramatic structure” to life, which is otherwise messy with chaos. I thought of that line when I read Amazon’s “Great Sentence” from Daniel Kahneman’s new book — and it made me crave the security of books that much more. He wrote:


“The world makes much less sense than you think.”

But further down their Facebook page, Amazon also seemed to offering a “counter-quote” from the same book — which shows just how rich a reading experience can be.


“Experts are just humans … They are dazzled by their own brilliance and hate to be wrong.”

To bring this all back around — to me that sounds a lot like Steve Jobs!
