Evolution of A Good Cry

A study by an evolutionary biologist provides confirmation that crying, an activity that can signal physiological pain, is also a highly evolved emotional behavior.

The analysis by Dr. Oren Hasson of Tel Aviv University reviews experiential evidence showing that tears have emotional benefits and can make interpersonal relationships stronger.

“Crying is a highly evolved behavior,” explains Dr. Hasson.

“Tears give clues and reliable information about submission, needs and social attachments between one another. My research is trying to answer what the evolutionary reasons are for having emotional tears.

“My analysis suggests that by blurring vision, tears lower defenses and reliably function as signals of submission, a cry for help, and even in a mutual display of attachment and as a group display of cohesion,” he reports.

Hasson’s research, which is published in Evolutionary Psychology, reviews the different kinds of tears we shed — tears of joy, sadness and grief — as well as the authenticity or sincerity of the tears.

Crying, Dr. Hasson says, has unique benefits among friends and others in our various communities.

Approaching the topic with the deductive tools of an evolutionary biologist, Dr. Hasson investigated the use of tears in various emotional and social circumstances.

Tears are used to elicit mercy from an antagonistic enemy, he claims. They are also useful in eliciting the sympathy — and perhaps more importantly the strategic assistance — of people who were not part of the enemy group.

“This is strictly human,” reasons Dr. Hasson. “Emotional tears also signal appeasement, a need for attachment in times of grief, and a validation of emotions among family, friends and members of a group.”

Crying enhances attachments and friendships, says Dr. Hasson, but taboos still exist in certain cases.

In some cultures, societies or circumstances, the expression of emotions is received as a weakness and the production of tears is suppressed. For example, it is rarely acceptable to cry in front of your boss at work — especially if you are a man, he says.

Multiple studies across cultures show that crying helps us bond with our families, loved ones and allies, Dr. Hasson says. By blurring vision, tears reliably signal your vulnerability and that you love someone, a good evolutionary strategy to emotionally bind people closer to you.

“Of course,” Dr. Hasson adds, “the efficacy of this evolutionary behavior always depends on who you’re with when you cry those buckets of tears, and it probably won’t be effective in places, like at work, when emotions should be hidden.”

Dr. Hasson, a marriage therapist, uses his conclusions in his clinic. “It is important to legitimize emotional tears in relationships,” he says.

“Too often, women who cry feel ashamed, silly or weak, when in reality they are simply connected with their feelings, and want sympathy and hugs from their partners.”
