|In the 1970s, American sociologists James Dabbs and Neil Stokes conducted a sidewalk study, wherein they measured changes in personal space around people as they walked against passerbyers on sidewalks, finding that beautiful women were allotted more personal space measured in inches. |
In the early 1970s, American sociologists James Dabbs and Neil A. Stokes III, of Georgia State University, conducted a study, the research of which supported by a US Public Health grant (HH20660), involving three experiments, in an attempt to discern changes in personal space (volume around a person) with respect to beauty, when a person is in motion, in an attempt to bring quantification to the famous idiom “beauty is power”, the abstract of the results of this study, published in 1975 as “Beauty is Power: the Use of Space on the Sidewalk”, is the following: 
“In three experiments, 470 pedestrians were observed as they walked past confederates standing on the edge of a sidewalk. Observations were made from a window overlooking the area, using time lapse filming with a movie camera. Pedestrians were observed as they moved along the sidewalk, and their distances from the edge of the sidewalk was measured at several points. Pedestrians deviated in their paths to stay farther from a male than a female, father from two people than from one person, and farther from a beautiful than an unattractive woman. Sex, number, and attractiveness may be regarded as aspects of power, which serve to dominate various amounts of a space.”
This study, along with the similar 1974 study “Body Height, Position, and Sex as Determinants of Personal Space”, conducted on 41 males and 43 females, in a laboratory setting by American psychologists Johan Hartnett, Kent Vailey, and Craig Hartley, were in combination summarized by American beauty researcher Nancy Etcoff (1999), as follows: 
“As we walk down the street, we negotiate space with other people. We carry a small territory with us, a protected turf that surrounds us whether we are sitting or standing, and upon which others cannot trespass without permission. Move in too close, and people get uncomfortable. Tall people have bigger territories: their sheer size intimidates people. When people are asked to approach a stranger and stop when they no longer feel comfortable, they will stop about two feet away from a tall person (22.7 inches to be exact) but less than a foot (9.8 inches) from a short person. Very attractive people of any size are given personal territories; they carry their privileges around their persons.”
This "trespass without permission" brings to mind both the 1970 chimpanzee war and the 2001 9/11 attacks, both the result "territory trespassing" repercussions, a led into the topic of war thermodynamics.
In 1976, Stokes and Dabbs, presented the results of a similar video-recorded interaction study of dyads discussing topics on which the agreed and ones on which they disagreed, the results analyzed by a computer. (Ѻ)
