Huffpo quantifies the meaning of a romantic relationship:

When you choose a life partner, you’re choosing a lot of things, including your parenting partner and someone who will deeply influence your children, your eating companion for about 20,000 meals, your travel companion for about 100 vacations, your primary leisure time and retirement friend, your career therapist, and someone whose day you’ll hear about 18,000 times.

Intense shit.

So given that this is by far the most important thing in life to get right, how is it possible that so many good, smart, otherwise-logical people end up choosing a life partnership that leaves them dissatisfied and unhappy?

Instead of doing serious research, most of us do our search haphazardly, falling prey to the availability heuristic:

In a study on what governs our dating choices more, our preferences or our current opportunities, opportunities wins hands down — our dating choices are “98 percent a response… to market conditions and just 2 percent immutable desires. Proposals to date tall, short, fat, thin, professional, clerical, educated, uneducated people are all more than nine-tenths governed by what’s on offer that night.”

In other words, people end up picking from whatever pool of options they have, no matter how poorly matched they might to be to those candidates. The obvious conclusion to draw here is that outside of serious socialites, everyone looking for a life partner should be doing a lot of online dating, speed dating, and other systems created to broaden the candidate pool in an intelligent way.
