The SEARCH Engine of Love: How Long Do You Need to Spot True Love?

How long does it take to know that you’ve found The One—or someone who you might want to see for a second date?


I found the answer to this and other existential questions in the Sky Mall catalog on a flight home, sandwiched amid ads for Big Foot garden statuary and anxiety-reduction blankets for cats.

 The answer is 20 minutes. At least this is the answer provided by the largest percentage (45%) of participants in a survey sponsored by the dating service, It’s Just Lunch.

 They asked, “How much time do you need” on a first date to decide if you have interest in the person? The runner-up answer, at 33%, was “about an hour.” A ruthless 12% said “5 minutes,” and only 7% said “over an hour.”  If I were single, I’d rush into the bold, recklessly inefficient arms of the last 3% of participants, who responded, “I always agree to see someone else again.”

 The distribution of answers, which keeps the required amount of time within the standard lunch hour, suits the needs of It’s Just Lunch, since their premise is that dating is more convenient and less awkward when you can confine it to a casual lunch hour, rather than having to make the scary commitment to a dinner (and I do know at least two people who have used this service and found partners through it).

“Speed dating” makes It’s Just Lunch look like an arduous long-term relationship, however. Here, you get six minutes to prove your human value and charm.

You probably know how speed dating works. When I was working on my book I went to a trendy bar to observe it. The host organization, founded in 2000, graciously allowed me to watch without having to participate and subject myself to dating market forces.

On the first floor of the bar was the bustling, tipsy romantic melting pot of a happy hour. On the second floor was the speed dating event. Nine mostly 30-something women sat, alone and silent, at small tables. They each had a number. The exuberant scene downstairs had been rationalized into makeshift cubicles, like an office. Their would-be partners sat alone and silent at other corners of the bar, as the official event hadn't begun. When the whistle blew (literally) the men progressed to the first station. They spent six minutes chatting, then each filled out a score card on the other, and moved to the next station.

It didn’t look like anyone made a love match that night. The event made me melancholy. These people must have come dreaming of some romantic epiphany. But their lives boiled down to a few mutually listless minutes. It seemed cruel to me, in the same way that I find agri-business to be cruel. Speed dating is to the bar scene as agri-business is to a family-run farm. It rationalizes the natural romantic chaos. You have your stall/table, and you are on the clock.  It’s a rotten thing to do to a tender heart—but that’s only my view, because speed dating remains popular, and it’s appreciated as a less harmful, efficient way to meet people.

 A lunch hour isn’t much time; six minutes even less. But you can get vastly more efficient than that, and shave minutes off of your judgments and decisions.

 AnswerLab does “neuromarketing” and is a leader in “interactive gaze technology.” They conducted a “field-based eye-tracking study” of online dating habits. They took their eye-tracking devices to a San Francisco café and had participants view different profiles from Match.com and eHarmony. Their technology allowed them to measure gaze patterns precisely, and to determine how much time each subject-consumer spent viewing different elements of each profile.

 AnswerLab discovered that women are more “careful consumers” of other humans as potential mates. Women spent nearly 50% more time than men to assess whether someone’s profile might be a match.

 But look at how much time these leisurely women spent: an average of 84 seconds. Men spent 58 seconds.

 20 minutes. Six minutes. 58 seconds. Don’t fence me in to an entire hour.

Love’s window of opportunity is shrinking. Our idea of a reasonable period of romantic exploration is metered in seconds.

It may be that we’re all just that good at appraising potential lovers, intuitively. It could be true. Or it may be that when you look for six seconds, you can find only what you expect to find, with potentially seductive quirks and depths of character remaining submerged under surface presentation.

 The mood is Tayloristic, a time-and-motion study, where efficiency is prized. There is a “getting it over with” spirit to mate selection in the new, hyper-accelerated modes.

 Love is a search. Think about the other SEARCH engines and functions in our lives. 

My WINDOWS “search” function can find an obscure phrase in a word file for me in well under a minute. That’s a sluggish pace compared to Google and other search engines.  Google quietly boasts that it found my 3,250,000 mostly irrelevant results for “plum pudding” in precisely 0.21 seconds; my inquiry about the Plevna Delay in the Russo-Turkish war found 640,000 results in 0.28 seconds.  You can’t stump Google. “What is Love” yields 3,720,000,000 results in 0.24 seconds.

 When we search for things, it takes so very little time to find them. The gap between desire, action, and gratification is so tiny. It is measured in a fraction of a second. The space between a question and its resolution is infinitesimal.

 If this is true for plum pudding recipes, it may also be true for love. The concept of the “search” and the quest have perhaps been globally and indiscriminately accelerated by the new technologies. The pacing and plotting of life has changed, and that change isn’t easily quarantined to the office.

 I don’t want to draw the point too finely, between the fast-paced, impatient judgments of humans in romance, and the speed we’ve come to expect in other, more prosaic searches of life.

Then again, these are the algorithms of our lives. Seek and ye shall find—efficiently, and in under half a second. We can’t expect that the new means of production, and life, won’t infiltrate our hearts in unintended ways, just as the wondrous new “machine age” of the 1800s and the assembly line of the early 1900s accelerated the tempo of our lives. They made life jazzier, gave it a faster beat, and focused on ever-more minute units of time, from which efficiency and yet faster production could occur.

 The technology of our age will surely do the same, in ways that we can’t always see or appreciate when they’re happening.

Quantum computing is on the way

Ready your Schrödinger's Cat Jokes.

Quantum entanglement. Conceptual artwork of a pair of entangled quantum particles or events (left and right) interacting at a distance. Quantum entanglement is one of the consequences of quantum theory. Two particles will appear to be linked across space and time, with changes to one of the particles (such as an observation or measurement) affecting the other one. This instantaneous effect appears to be independent of both space and time, meaning that, in the quantum realm, effect may precede cause.
Technology & Innovation
  • For a time, quantum computing was more theory than fact.
  • That's starting to change.
  • New quantum computer designs look like they might be scalable.

Quantum computing has existed in theory since the 1980's. It's slowly making its way into fact, the latest of which can be seen in a paper published in Nature called, "Deterministic teleportation of a quantum gate between two logical qubits."

To ensure that we're all familiar with a few basic terms: in electronics, a 'logic gate' is something that takes in one or more than one binary inputs and produces a single binary output. To put it in reductive terms: if you produce information that goes into a chip in your computer as a '0,' the logic gate is what sends it out the other side as a '1.'

A quantum gate means that the '1' in question here can — roughly speaking — go back through the gate and become a '0' once again. But that's not quite the whole of it.

A qubit is a single unit of quantum information. To continue with our simple analogy: you don't have to think about computers producing a string of information that is either a zero or a one. A quantum computer can do both, simultaneously. But that can only happen if you build a functional quantum gate.

That's why the results of the study from the folks at The Yale Quantum Institute saying that they were able to create a quantum gate with a "process fidelity" of 79% is so striking. It could very well spell the beginning of the pathway towards realistic quantum computing.

The team went about doing this through using a superconducting microwave cavity to create a data qubit — that is, they used a device that operates a bit like a organ pipe or a music box but for microwave frequencies. They paired that data qubit with a transmon — that is, a superconducting qubit that isn't as sensitive to quantum noise as it otherwise could be, which is a good thing, because noise can destroy information stored in a quantum state. The two are then connected through a process called a 'quantum bus.'



That process translates into a quantum property being able to be sent from one location to the other without any interaction between the two through something called a teleported CNOT gate, which is the 'official' name for a quantum gate. Single qubits made the leap from one side of the gate to the other with a high degree of accuracy.

Above: encoded qubits and 'CNOT Truth table,' i.e., the read-out.

The team then entangled these bits of information as a way of further proving that they were literally transporting the qubit from one place to somewhere else. They then analyzed the space between the quantum points to determine that something that doesn't follow the classical definition of physics occurred.


They conclude by noting that "... the teleported gate … uses relatively modest elements, all of which are part of the standard toolbox for quantum computation in general. Therefore ... progress to improve any of the elements will directly increase gate performance."

In other words: they did something simple and did it well. And that the only forward here is up. And down. At the same time.

Why Japan's hikikomori isolate themselves from others for years

These modern-day hermits can sometimes spend decades without ever leaving their apartments.

700,000 Japanese people are thought to be hikikomori, modern-day hermits who never leave their apartments (BEHROUZ MEHRI/AFP/Getty Images).
Mind & Brain
  • A hikikomori is a type of person in Japan who locks themselves away in their bedrooms, sometimes for years.
  • This is a relatively new phenomenon in Japan, likely due to rigid social customs and high expectations for academic and business success.
  • Many believe hikikomori to be a result of how Japan interprets and handles mental health issues.

Scientists discover what caused the worst mass extinction ever

How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.

Surprising Science

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
