The Science Of Relationships: What Draws Us Together?

When it comes to relationships, there are a lot of different factors that come into play. What attracts two people together is a complex question that scientists have studied for many years. And as it turns out, the answer is not simple—there’s no universal formula for a successful relationship. However, some elements of the science of relationships are worth exploring, and that is exactly what this article aims to do! In it, you will learn about the different factors that can influence relationships, from biology to personality traits.

What Makes Relationships So Unique?


Relationships have a special and unique quality to them from a scientific point of view. Studies have shown that when people are close to someone, their levels of oxytocin, also known as the ‘hormone of love’, increase significantly and help marriages and friendships stay strong. Intimate relationships also cause dopamine levels to spike – the chemical responsible for happiness!

Even more interesting is that scientists have determined that these hormonal changes can be felt in both parties of a relationship at once, indicating an inherent biological connection between two people who consider each other “special”. This further reinforces what many believe to be true about relationships: whatever humans experience with their loved ones is far more profound than surface-level interactions.

The Elements The Effect The Science Of Relationships

As most people know, explaining what brings two people together can be challenging. Despite this, scientists have been able to identify a few key elements that are necessary for successful relationships. Here are a few essential factors to consider when thinking about relationships:



The science of relationships takes a lot of its cues from biology. From the moment people meet, their biologies come into play, shaping their connection. Hormones such as oxytocin are released in your body when you bond with another person, creating a positive visceral reaction towards them. You also experience biological responses to rejection, such as the loss of serotonin or spikes in cortisol which can make it difficult for you to cope with feelings of loss or abandonment.

Understanding biology’s role in relationships should allow you to comprehend better how love and interpersonal connection work. Biology doesn’t just influence how you build relationships but also how you process emotions within them. This can be seen in studies where couples who are feeling overwhelmed emotionally show an increase in fatalistic thought patterns or self-destructive behaviors that could lead to even more tension within their partnership.



The use of pheromones to help explain the science behind relationships is a concept that has generated a great deal of debate among scientists. At its core, pheromones are chemicals secreted to alter another organism’s behavior or physiology. The idea that these secreted chemicals can be used to make someone more attractive has been studied by researchers for many years. To truly understand the potential effect pheromones have on humans, it is important to look more closely at their role in mating behavior and how they can be used to build relationships.

Studies have shown that although humans secrete fewer odors than other animals, pheromones still significantly influence people’s behavior and emotions. For example, studies have observed increased arousal levels among male participants when exposed to specific female-produced pheromones and increased trust between people who identify with similar compounds. Intriguingly, even before conscious knowledge or attraction is present, relationships may be formed through the recognition between shared scents and hormones.

Physical Traits


Physical traits can play an essential role in the science of relationships, with particular body language or facial expressions being created almost unconsciously. While physical attraction is not the primary basis for a strong relationship, physical characteristics still significantly impact how both partners feel about one another and how secure they are in the relationship. Body language conveys messages like verbal communication does, revealing even more information than most people realize.

How two people stand close to each other, how they make eye contact, and the inflections of their voices, for example, all reveal important cues about their relationship and connection. Additionally, having similar physical features may increase feelings of closeness between two people – perhaps them feeling a stronger sense of ‘having something in common’. Therefore, whether consciously or not, physical traits affect the science of relationships in many ways.

Personality Traits


The science of relationships has been the focus of study for years, and the notion of personality traits affecting them is at the center of this field. How an individual behaves in relationships could depend heavily on their preferences, needs, and temperament. Understanding how these personal characteristics manifest in different reactions is vital to creating successful relationships that thrive and grow.

Personality traits can drive decisions like which individuals will be attracted or repelled by each other, how they respond to obstacles or disagreements, and what kinds of communication styles they might gravitate towards. Therefore, dealing with certain personalities can directly inform how effective any relationship can be over the long term. Keeping a mindful eye on these factors helps to safeguard the bonds people create with each other.



Evolution has also significantly impacted the science of relationships, leading to a better understanding of the different factors influencing them. By studying prehistoric correlations between survival strategies and modern-day behaviors, experts gain valuable insights regarding what motivates people’s relationships and how they can be improved. Through evolutionary psychology, theorists can look at biological imperatives, such as mate selection and attachment styles, which impact your connections with others.

From examining how social norms have changed over time to creating models that assess the effectiveness of communication between partners, evolution provides critical pieces to the puzzle in helping scientists to better understand what makes relationships successful. In turn, this knowledge can be invaluable to individuals, who can apply it in their own lives.



Neuroscience, the scientific study of the nervous system and its functions, has played an increasingly important role in understanding the science of relationships in recent years. Researchers can now use various tools, such as Functional Magnetic Resonance Imaging (fMRI) and Electroencephalography (EEG), to explore how people process emotions, interpret social cues and interact with others. In addition to these studies of how the brain works, neuroscience research also reveals important insights about how behavior and interaction affect cognition.

This new knowledge sheds light on why some relationships can be strong and healthy while others become mired in misunderstandings or mistrust. As science continues to reveal the intricate inner workings of relationships, individuals can use this valuable information to discover more effective ways to build meaningful connections with others.

The Science Of Relationships Can Be Life-Changing!

The science of relationships is complex, with many different aspects studied for years. These elements combine to provide scientists with deep insight into creating meaningful relationships. By understanding how these factors interact in your life and relationship, you can build stronger, more successful connections with those around you.
