According to the biblical book Numbers, so that the Israelites did not forget the favors granted, blue ribbons were placed on their mantles. This led to the belief that blue remedied certain evils and granted protection. Therefore, for centuries something blue has been placed in the clothes of babies of sex that has always been more desired: the men.
As for girls' pink, the legend says that girls are flowers that are born under the petals of roses and associate these flowers with Venus, the goddess of love. However, apart from myths and legends, is it true that boys prefer blue and girls prefer pink? Or is it just a cultural imposition rooted in tradition?
Innate or cultural?
In 2007, a group of researchers from the University of Newcastle asked a group of men and women to choose between colored rectangles. Both genders preferred various shades of blue, but women showed greater preference than men for reddish tones. As he explains Christian Jarret in his book Great myths of the brain:
The researchers speculated that throughout history women had specialized more in fruit collection than in hunting, and that this "supports the female preference for objects that are redder than the environment."
However, there are other studies that reject this innate preference, such as one conducted in 2011 by Vanessa LoBue Y Judy DeLoache, which presented to 192 boys and girls between seven months and five years of age several pairs of small objects of different colors. After two years of age, girls preferred pink, and boys rejected it. But that trend did not appear before two years of age, which is when you begin to be gender aware.
In fact, culturally it seems that the association of these colors to the male and female sex is quite recent. According to research by Giudice Frame, from the University of Turin, the phrases "blue for children," pink for girls ", began to appear around 1890 and intensified after World War II.
So? Innate or learned? Well, it seems that studies suggest that I learned, unless more evidence is found to indicate otherwise:
Among the Namibian himba, an ethnic group totally separated from Western consumerist culture, they found no sign that women preferred reddish or pink tones.
