While some have avoided using the term “addiction” in the context of natural compulsions such as uncontrolled sexuality, overeating, or gambling, let us consider current scientific evidence regarding the brain and addiction.
This article will seek to answer two questions: (1) Biologically, is the brain affected by pornography and other sexual addictions? (2) If so, and if such addictions are widespread, can they have a societal effect as well?
The Story of the Gypsy Moth
Let’s begin with a seeming digression. In 1869 the gypsy moth was brought to America to attempt to jumpstart a silk industry. Rarely have good intentions gone so wrong, as the unforeseen appetite of the moth for deciduous trees such as oaks, maples, and elms has devastated forests for 150 years. Numerous attempts were made to destroy this pest, but a major breakthrough came in the 1960s, when scientists noted that the male gypsy moth finds a female to mate with by following her scent. This scent is called a pheromone, and is extremely attractive to the male.
In 1971 a paper was published in the journal Nature that described how pheromones were used to prevent the moths from mating. The scientists mass-produced the pheromone and permeated the moths’ environment with it. This unnaturally strong scent overpowered the females’ normal ability to attract the male, and the confused males were unable to find females. A follow-up paper described how population control of the moths was achieved by “preventing male gypsy moths from finding mates.”
The gypsy moth was the first insect to be controlled by the use of pheromones, which work by two methods. One is called the confusion method. An airplane scatters an environmentally insignificant number of very small plastic pellets imbedded with the scent of the pheromone. Then, as science journalist Anna Salleh describes it, “The male either becomes confused and doesn’t know which direction to turn for the female, or he becomes desensitized to the lower levels of pheromones naturally given out by the female and has no incentive to mate with her.”
The other method is called the trapping method: Pheromone-infused traps are set, from which moths cannot escape; a male moth enters looking for a female, only to find a fatal substitute.
