A handshake really does make a difference.
“a handshake preceding social interaction enhanced the positive impact of approach and diminished the negative impact of avoidance behavior on the evaluation of social interaction.”
“We found that it not only increases the positive effect toward a favorable interaction, but it also diminishes the impact of a negative impression. Many of our social interactions may go wrong for a reason or another, and a simple handshake preceding them can give us a boost and attenuate the negative impact of possible misunderstandings.”
5 things people can tell about you from your handshake:
1) There is a connection between the quality of that handshake after a job interview and whether or not you get an offer.
2) People can tell how extraverted and conscientious you are by your handshake.
4) You can judge someone’s overall health by a handshake.
5) Your handshake says a lot about you sexually as well.
What can we tell about someone’s personality from their handshake?
We examined whether handshakes improved the accuracy with which participants judged a set of targets. Handshakes are interpersonally coordinated behaviors that require motivation and practice to perform well. Therefore conscientiousness may predict how well handshakes are executed. If so, a person’s conscientiousness may be more accurately perceived at zero-acquaintance through a handshake. Individual female and male participants rated the personality of five, same-gender targets after each had introduced herself or himself. Half of the targets offered and shook hands with the participant as part of the introduction, half did not. Extraversion was judged most accurately, regardless of handshake condition. Handshaking moderated impression accuracy of conscientiousness, especially between men, which may explain the importance business professionals place on face-to-face interviews.
What does your handshake say about you?
People with high grip-strength scores are usually healthier than those with weak grips. “They live longer and recover faster from injury,” Gallup says. “They have reduced disability, higher bone density and greater fat-free body mass.” And in a study published this year, Gallup and his son Andrew — at the time an undergraduate psychology major — found that males with high grip-strength scores reported being more aggressive and dominant and had more masculine body types (broader shoulders, narrower hips). They also had “increased sexual opportunities,” which resulted in an increased number of sexual partners, and younger ages of first sexual encounter. (For women, handgrip may be more about sexual protection than prowess: Gallup has found that women’s hand strength increases when they’re most fertile, a trait he says may have evolved to prevent forced impregnation by unwanted mates.)
What does your grip say about you?:
A hell of a lot, especially if you’re male:
Handgrip strength (HGS) is a noninvasive measure of physical health that is negatively correlated with disability, morbidity, and mortality rates in adults. Highly heritable, HGS is indicative of blood testosterone levels and levels of fat-free body mass. In this study, we investigated whether HGS was related to measures of body morphology [shoulder-to-hip ratio (SHR), waist-to-hip ratio, and second-digit-to-fourth-digit ratio (2D:4D)], aggressive behavior, and sexual history in 82 male and 61 female college students. Results showed that ‘Handgrip strength’ was correlated with SHRs, aggressive behavior, age at first sexual intercourse, and promiscuity in males but not in females. HGS appears to be an honest signal for genetic quality in males.
How much does a firm handshake matter during a job interview?
Quality of handshake was related to interviewer hiring recommendations.
