I want to somehow know the feelings of the opposite sex that I am interested in. Do you like yourself or don't think of it at all?
A research group at the University of Granada in Spain has published findings that it is (to some extent) scientifically measurable whether a person is in love. If you measure your body temperature with a thermography, it seems that the person's feelings are crazy.
The survey was conducted on 60 men and women between the ages of 24 and 47 who had just started dating within a few weeks. The survey method is to have the subject sit naked in the room, show the image displayed on the computer screen, and record the change in body temperature at that time by thermography. Half of the people surveyed were shown images of their dating lover, and the other half were shown images of their family and friends.
As a result, the body temperature of the subject who was shown the image of his lover increased by 1 to 2 degrees around the cheeks, hands, chest, mouth, and genitals. On the other hand, it seems that there was no change in the body temperature of the subjects who were shown images of family and friends.
The drawback of this survey is that it cannot be easily reproduced. It's hard to create a situation where you ask the person you care about to sit naked and measure with thermography. But you can see the changes in color of the cheeks, hands, and mouth. And even with that alone, it seems that the feelings of the other party can be guessed with a high probability.
You're good at persuading both men and women, aren't you? If you ask them, they will generally know if they will fall before they argue. Perhaps such people are naturally sensitive to changes in their partner's temperature.
People's "mind and behavior" and "body temperature" are closely related. For example, many people say that when they lie, the temperature at the tip of their nose changes. This phenomenon is called the "Pinocchio effect", and a research group at the University of Granada is also using thermography to study this Pinocchio effect.
When you lie, your nose grows ... but the temperature changes. It may be useful to be able to identify this as well. For example, his or her affair may be detected by just looking at his nose.
Recently, "Google Glass" has completely faded. But if you add a function that tells you if he or she likes you, it will be popular at once. If you install a function to detect cheating, it may sell even more. There will be many people who are in trouble, but if there is an app that gives a number such as "Favorability from this person: XX%" just by looking at the other person's face, I feel like trying it once.
