The limbic brain picks up the positivity, which will make the interviewer comfortable, Wood says.
"It’s one of the reasons we shake hands, to show the open palm," Wood says. If we don’t see open palm gestures, it puts us on our guard." In general, upward-facing body language, such as open palms, smiles and straight posture, also makes you look energetic, Glass says.
Wood and Reiman both recommend keeping feet firmly the ground.
Women should never cross at the knees, but rather the ankles, "as this allows them to switch if necessary without being obvious." There's also a scientific benefit to keeping your feet grounded.
A more effective way to ensure you look interested and engaged is to look different parts of someone's face every two seconds, rotating from eyes, to nose, to lips, so you're never just drilling into the interviewer's eyes.
When your palms are up, it signals honesty and engagement.
It's also a legitimate way to portray good body language during a job interview. You want to be confident, but not obnoxious; intelligent but not a know-it-all.
Ask your date an easy question like what he wanted to be when he grew up or his greatest passion.
Once he’s relaxed, observe the four C's—comfort, context, consistency, and clusters.
"It’s not impossible, but it’s difficult to answer highly complex questions unless both of your feet are on the ground," Wood says.
"It has to do with being able to go back and forth easily between the limbic reptilian brain to the neocortex brain." In layman's terms, planted feet can help you go between creative thought and highly complex rational thought.
