Why do we love? Is it part of human evolution? What in our biology makes us strive for love and intimacy? And how do we make it last? This week we welcome Dr. Helen Fisher, TED talk all-start and author of Anatomy of Love - A Natural History of Mating, Marriage and Why We Stray. In this episode we dive head first into how long-term partnerships fit into what makes us human - along with some thoughts about breaking up, serial monogamy, and what makes love last. Helen Fisher is the Chief Scientific Advisor to Match.com as well as a Senior Research Fellow at the Kinsey Institute. You’ll appreciate how her knowledge of the science of love can give us the roadmap to long-lasting happiness in relationship. We are built to fall in love. Is the quest for long-term thriving monogamy futile? History, biology, and evolution show us that we are, in fact, built to create pair bonds. We are built to fall in love. Our brains are wired to feel intense feelings of romantic love and attachment. While there is biology to support attachment structures, there is also biology to support the drive to wander, and to cheat. To reconcile these concepts it is important to know that pair bonding is different than monogamy. Every individual, couple, and culture needs to figure out how to navigate what attachment in the context of romantic love means. Serial monogamy? In hunting and gathering societies serial monogamy was not necessarily the golden standard or expectation for coupling. However, women and men tended to have 2-3 spouses during the course of their lives. We have most likely evolved to have a series of partnerships throughout our lives. While culture plays a major role in how this is expressed, we see it happening more and more in people in their 20s and 30s.  Before tying the knot.  Research shows that over 50% of single Americans have had a one night stand or friends with benefits. This is not reckless, in fact, it very well might be helping establish healthier marriages. There is a current trend in the United States in which the pre-commitment stage of relationships is being extended. 67% of people who live with their significant other say they have not married yet because they are worried about divorce. That said, 81% of people who married later say they would marry the same person again if they had a second chance. The longer you are together pre-marriage, the more likely you are to try to stick together, and this results in a sharp decrease in divorce rates. This is true because the time spent together gives you the chance to really know who you are marrying, and give the relationship time to work itself out, or not.  4 year itch- Data shows that most people will divorce around 3-4 years of marriage. This is likely no coincidence. It takes 3-4 years to raise a child through infancy, and it seems evolutionarily beneficial to have evolved a predisposition for serial pair bonding linked with having one child at a time, and then to seek another partner as an adaptive strategy evolutionarily to have kids with different partners, creating genetic variety. Rebuilding local community- We may be putting too much pressure and improbably expectations on our partnerships due to the fact that we have lost local community. It used to be that marriages were surrounded by family and community and could depend on help from others to help raise children. The loss of local community is a very serious issue facing contemporary marriages, and it is very important that we focus on rebuilding these social networks. Find, create, nurture, and invest in your friendship circles as an extension of and protection for, your primary relationship. Happiness in the brain: Research results from the study of people in long term self-reported happy marriages shows an increase in activity in 3 brain regions. These three areas serve to facilitate the function of 1) empathy, 2) controlling our emotions, and 3) increasing our ability to overlook what we do not like about our
