Mathematicians have racked their brains and abacuses, for the good of society, in order to help us all choose wisely the person who shares our king-size. According to New Scientist, the law of diminishing returns has long been thought to be a marvelous indicator of when to stick, rather than turn another card…

However, then along came John Gilbert and Frederick Mosteller of Harvard University. I do not believe they were married. However, they came upon the idea that the magic number is, in fact, 37. Yes, you should stop after 37 candidates and choose the next best one. This number was apparently derived by taking the number 100 and dividing by e, the base of the natural logarithms (around 2.72). And it apparently increases your chances of the best choice to 37 percent.

Here’s the real beauty of this calculation, though. You don’t have to limit yourself to 100. This optimization works for any population. So if you have a world of 26 potential life partners, simply divide by 2.72 and choose the next best one.
