Use of scripts:âMastering Lifeâs Decisions Through Algorithms
Imagine youâre hunting for an apartment in one of the toughest cities to find a place, like San Francisco. You only have a limited time to look, and as each new apartment comes onto the market, you either have to commit immediately or let it go forever. This was exactly the situation a friend of mine found himself in not too long ago, and as the days went by, he grew more anxious. He visited apartment after apartment, each one a little better or a little worse than the last, and every time, he left thinking, âIs this the best Iâm going to find, or should I keep looking?â
What he didnât know was that his problem had a clear solution, and itâs something computers use every day: the 37% rule. According to this rule, you should spend the first 37% of your time gathering data without committing. Once youâve hit that mark, take the first option that is better than what youâve seen so far. Itâs a surprisingly efficient strategy that applies not only to apartment hunting but to any decision where you have to stop at the right moment, like hiring an employee, choosing a parking spot, or even picking a life partner. My friend didnât know this at the time, but once he hit the 37% mark of his month-long search, he committed to the next great apartmentâand, as it turned out, it was the best choice he couldâve made.
Now, itâs not always easy to know when to stop looking, especially when the stakes are high, but this rule gives us a way to balance looking and leaping. Itâs about knowing when youâve gathered enough information to make a confident decision without endlessly second-guessing yourself. As the 37% rule suggests, making informed decisions doesnât mean chasing perfection. It means timing your commitment just right.
Speaking of timing, letâs talk about the everyday struggle of finding a parking space. Donald Shoup, an urban planner who has spent decades studying parking, believes that drivers spend far too much time circling blocks, searching for that perfect parking spot close to their destination. I know a friend who once spent nearly 20 minutes circling the block, passing by open spaces again and again, each time thinking, âMaybe thereâs something closer.â By the time he finally settled for a spot far from where he needed to be, he was exhausted, frustrated, and late.
What Shoupâs research shows us is that parking, too, is an optimal stopping problem. The secret is knowing when to stop searching and take the next available spot. The longer you search, the more likely you are to waste time and fuel. Shoup argues that cities should reduce the occupancy rate of parking spaces by adjusting prices, aiming for an 85% occupancy rate rather than the nearly 100% we often see. That 15% availability would mean fewer cars cruising endlessly, reducing traffic and pollution. My friend could have saved himself time and stress had he known about the Look-Then-Leap strategy. The takeaway here is simple: sometimes, the âgood enoughâ option is the best one.
This brings us to one of the most fascinating applications of the 37% rule: finding love. Letâs take Michael, a mathematician who applied this strategy to his own dating life. He had calculated, based on his age, that he would probably meet a certain number of women in his lifetime, and he decided to wait until he had dated 37% of that number before committing to the next woman who seemed better than all the others. The math was solid. He dated a number of women, hit his 37% mark, and then found someone who, by all measures, seemed perfect. So, naturally, he proposed.
But hereâs the twistâshe said no.
It turns out that while algorithms can help you make optimal decisions, they canât predict human emotions. Michaelâs story reminds us that love, like parking or apartment hunting, is about timingâbut itâs also about being flexible when life doesnât follow the numbers. And yet, Michael didnât give up. Later, he met someone else, fell in love, and, following his gut this time, made a commitment that worked out beautifully. While the 37% rule can guide us in timing when to stop, we must also be willing to adapt when the human heart throws a curveball.
Each of these stories brings us back to the same essential truth: life is full of decisions where we must balance the desire to explore new options with the need to exploit the ones weâve already found. Whether itâs finding an apartment, choosing a parking spot, or searching for love, the 37% rule gives us a framework for knowing when to act. However, as we see with Michaelâs story, life doesnât always fit neatly into a formula. While algorithms can guide our choices, they canât control everything, and sometimes, we must trust our instincts and be prepared for the unexpected.
As weâve seen, decisions are rarely about finding the perfect solution; theyâre about finding the best possible solution given the circumstances. The 37% rule teaches us that perfection is elusive, and itâs more productive to make decisions based on timing and the information we have than to endlessly search for a perfect outcome. Whether you're circling the block for a parking spot or looking for the love of your life, at some point, you have to commit.â
