Washington, Apr 12 (ANI): Brandishing a weapon makes a man appear bigger and stronger than he would otherwise, a new study has revealed.
For the study, UCLA anthropologists asked hundreds of Americans to guess the size and muscularity of four men based solely on photographs of their hands holding a range of easily recognizable objects, including handguns.
"There's nothing about the knowledge that gun powder makes lead bullets fly through the air at damage-causing speeds that should make you think that a gun-bearer is bigger or stronger, yet you do," Daniel Fessler, lead author of the study, said.
"Danger really does loom large - in our minds," he said.
According to the researchers, the findings suggest an unconscious mental mechanism that gauges a potential adversary and then translates the magnitude of that threat into the same dimensions used by animals to size up their adversaries - size and strength.
"We've isolated a capacity to assess threats in a simple way," Colin Holbrook, co-author of the study, said.
"Though this capacity is very efficient, it can misguide us," Holbrook said.
The researchers recruited participants in multiple rounds using classified advertisements on the websites Craigslist and MechanicalTurk. In one round, 628 individuals were asked to look at four pictures of different hands, each holding a single object - a caulking gun, electric drill, large saw or handgun.
"Tools were used as control objects to rule out the possibility that a simple link with traditionally masculine objects would explain intuitions that the weapon-holders were larger and stronger," Fessler said.
The individuals were then asked to estimate the height of each hand model in feet and inches based solely on the photographs of their hands.
Participants also were shown six images of progressively taller men and six images of progressively more muscular men and asked to estimate which image came closest to the probable size and strength of the hand model.
Study participants consistently judged pistol-packers to be taller and stronger than the men holding the other objects, even though the experiment's four hand models were recruited on the basis of their equivalent hand size and similar hand appearance (white and without identifying marks such as tattoos or scars).
To rule out the possibility that a feature of any one hand might influence the estimates, researchers had taken separate pictures of each hand holding each object - some participants saw the gun held by one hand model, others saw the same gun held by another model, and so on, they did the same thing for each of the objects.
The researchers also shuffled the order in which the photos were presented.
On an average, the participants judged pistol packers to be 17 percent taller and stronger than those judged to be the smallest and weakest men - the ones holding caulking guns. Hand models holding the saw and drill followed gun-wielders in size and strength.
"The function of the system is to provide an easy way for people to assess the likelihood that they would win or lose in a conflict," Jeffrey K. Snyder, co-author of the study, said.
Concerned that their findings might be influenced by popular culture, which often depicts gun-slingers as big and strong men, the team conducted two more studies using objects that did not seem to have a macho image - a kitchen knife, a paint brush and a large, brightly coloured toy squirt gun.
In the initial round, a new group of 100 subjects was asked to evaluate the danger posed by each of the objects (which were presented alone, without hands holding them). They then were asked to pick the type of person most associated with the object: a child, a woman or a man.
Not surprisingly, individuals rated the knife most dangerous, followed by the paint brush and squirt gun. But where the most lethal object in the earlier studies - the handgun - would likely have been associated with men, participants in this study most often associated the most lethal object - the kitchen knife - with women.
The paint brush was most often associated with men, and the squirt gun with children.
In the final round of tests, a new group of 541 individuals was shown male hands holding the knife, paint brush and squirt gun and was then asked to estimate the height and muscularity of the hand models.
Once again, men holding the most lethal object - in this case, the kitchen knife - were judged to be the biggest and strongest, followed by those holding the paint brush and the squirt gun.
"It's not Dirty Harry's or Rambo's handgun - it's just a kitchen knife, but it's still deadly," Holbrook said.
"And our study subjects responded accordingly, estimating its holder to be bigger and stronger than the rest," Holbrook added.
The study has been published in PLoS ONE. (ANI)
