Vacharkulksemsuk and colleagues investigated links between posture and likeability. Data collected via “two field studies . . . suggested that (i) expansive (vs. contractive) body posture increases one’s romantic desirability; (ii) these results are consistent across gender. . . . Expansiveness makes the dating candidate appear more dominant.” An example of an expansive posture is leaning backwards, in a reclining chair, for instance.
