Show Me Your Hand II

By Truth About Deception

Previous research shows that men, whose ring finger is longer than their index finger (on their right hand), experienced a surge of testosterone while in their mother’s womb.

A lot of masculine traits such as risk taking, aggression, and athletic skills have been linked to such differences in finger length (also called 2D:4D digit ratio).

New research shows that men with longer ring fingers compared to their index fingers are also more likely to confront a romantic rival when jealous.

Modern day palm reading?  Not really.  Just science exploring how heighten levels of testosterone influence physiological traits as well as aggressive behavior.


Netflix Adultery

By Truth About Deception

Lying never goes out of style.  People make promises to their partners and then find new ways to betray them.

The latest twist on this? Promising to watch a TV show with your partner, but then secretly viewing it by yourself – Netflix Adultery.  It is estimated that over fifty percent of people betray their partner’s expectations about watching TV shows together.  A key quote summarizing the findings:

“Of those who cheated, 66 percent did so “at home by themselves on the main TV.” A shocking 21 percent confessed to watching in bed while their significant other slept… Forty-one percent of cheaters refrained from revealing spoilers; 12 percent would rewatch and “fake it” in their reactions; 14 percent felt so guilty they confessed to cheating.”


Not Just a Dream

By Truth About Deception

New research shows that the content of one’s dreams has an impact on a romantic relationship.

Individuals, who dreamt that their partner’s were cheating on them, actually treated their partner’s differently when they awoke. If you dreamt that your partner was cheating, you were more likely to pick a fight and act distant the next day.

The most likely explanation – our dreams trigger (or prime) emotional reactions, upon which we subsequently act.

Even though it was just a dream, it has a real impact.


Sliding Versus Deciding

By Truth About Deception

Some people slide into their relationships. People hangout, spend time together, become a couple, move in, and they may even get married.

It is easy for couples to slide into a relationship. Sliding couples don’t talk about what they are doing, make their expectations clear, or think about their decisions. They go with the flow – what’s the point of discussing where the relationship is going and what it means to be together? If things are working, why talk about it? The classic example of sliding into a relationship – moving into together because you are already spending all of your time at one person’s place. Why not just move in and save some money, right?

Other people decide their way into a relationship. They think about what they are doing and make their expectations clear. They weigh the pros and cons of being in a relationship and talk about their feelings with their partner. They think about what their decisions mean before they act. Moving in together is a big deal. Let’s talk about what we expect from each other, where we want our relationship to go, let’s make sure we understand what we are getting into.

New research shows that people who decide their way into a relationship are more happy with the outcome, more dedicated to their partner, and less likely to cheat.

Sliding into a relationship may seem like the easy way to go. But sliding into a relationship is an easy route to sliding into a set of commitments that no one really agreed to.


Oral Sex Differences

By Truth About Deception

Oral sex is somewhat of a biological puzzle. Assuming that sex was designed for reproduction, what’s the purpose of oral sex? Oral sex typically doesn’t create a lot of children.

Researchers looking at the purpose of oral sex have linked it to infidelity. Men, who are more suspicious that their partners may be cheating, are more likely to engage in oral sex. It is thought that oral sex serves many purposes for men, including examining their partner’s vagina – does she taste or smell like she has been with another man? Revolting to think about, but some evidence supports this interpretation. A key finding from a recent study on the topic:

“Men but not women at greater risk of partner infidelity report greater interest in, and spend more time performing, oral sex on their partner. Furthermore, the relationships between partner infidelity risk and interest in, and time spent, performing oral sex are statistically larger for men.”

Women, by contrast, don’t use oral sex the same way that men do. The possible reasons for this difference are uncomfortable to contemplate. To begin with, sexually transmitted diseases are more easily contracted when women perform oral sex than men. Also, men leave more semen in women than women leave vaginal secretions on men. Taken together, it is more effective and less risky for men to use oral sex to detect infidelity than the other way around.
