Does science recognize love?

Every society has a romantic tradition, and the desire to form a long and (hopefully) lasting love with another human being is apparently an intrinsic part of being human. But while monogamy seems to be the ideal for most people, attaining that ideal is easier said than done. Like it or not, humans aren't likely to stay with one romantic partner for their entire lives. No matter how a society chooses to define marriage, nearly half of all such partnerships end in divorce.

Science cannot prove that your spouse loves you. When asked why so-and-so loves you, you may cite precedent (times when their behavior demonstrates their love for you) but this is a particular type of historical truth. There is no scientific test that can confirm a lifetime of experience of knowing a person.

Rubin (1970) introduced and validated a social-psychological construct of romantic love. Sternberg (1986) also came up with another theory called the Triangular Theory of Love.

In marketing, we also have a construct called Brand love. Based on the pioneering work of Rubin as well as that of other researchers, Carroll and Ahuvia (2006) proposed the brand love scale. This scale assesses satisfied consumers' passionate emotional attachment to particular brands and is is measured using 10 items or statements.

Can it be observed? Yes.  Can it be studied? Yes.  Can it be measured? Well, things about it can be measured: physiological reactions, emotional self-reports, long-term health effects.

Yes, science believes in love, because it can be demonstrated, observed, and tested.  There are some horrific experiments on primates about depriving them of parental love.  The results were so dramatic and horrible that they changed regulations on animal experimentation.

We can demonstrate love in MRIs, in skin galvanic response and heart rate, in both long-term and short-term hormonal responses.  We can do longitudinal epidemiological studies about the positive and negative effects of different forms of relationships.

We can show affection and love relationships in social animals as diverse as crows and rats.  We can observe cross-species altruistic behavior.

Science recognizes many different forms of love.

Fabulous question! I need a minute to enjoy it! Thank you very much for asking it.

YES. It is measurable scientifically. My knowledge is very limited on the science itself. Kinetic energy of the human body is measurable and I they are able to measure intimate love energy, and if memory serves me, measuring compassionate love was a challenge but again, I'm ignorant about the science itself. But I know the answer is Yes. Absolutely is scientifically detectable and measurable. At what levels, how, etc... Find out, and share it with everyone. Would be good to know more about it. Thank you for such a great question.

There is scientific research on love. There are even pop-science books summarizing the research every once in a while, such as: Falling in Love: Why We Choose the Lovers We Choose (9780415951876): Ayala Malach Pines: Books

But there isn't a definitive scientific measure for "being in love", if that's what you mean by "recognizing love". They measure self-reported interest in a partner, or call-back rates, or pulse and sweating.

yes, even science believe that..

The Science of Love

  • There are three phases to falling in love and different hormones are involved at each stage.
  • Events occurring in the brain when we are in love have similarities with mental illness.
  • When we are attracted to somebody, it could be because subconsciously we like their genes.
  • Smell could be as important as looks when it comes to the fanciability factor. We like the look and smell of people who are most like our parents.

How does advertising work in Saudi Arabia? What is the most convenient way to reach out to the public?

It largely depends on the product you are selling. Having lived in Saudi Arabia for over 15 years, I have witnessed several successful and failed advertising campaigns. And one common aspect of most successful campaigns is the presence of a 'personal touch'.A vast majority of Saudi people simply

Why do people get constipated from drinking too much coffee?

In a TCM (traditional chinese medicine) perspective, they consider food to have various effects on the body. Food has been strategically categorized by their respective "taste" and "temperature" such as sweet, salty, sour, bitter, hot, cold, etc. Coffee is most definitely considered to be a bitter and hot food in the TCM world. All bitter foods are known

Why did Red Lobster end its Endless Shrimp deal?

It never really ends as it is an annual promotion that runs from September to early November. We can't afford to run it year long because of the cost of labor needed to run the front of house (servers, hosts) and the back of house (kitchen). At our store, we have to
