Summary

Harry Harlow conducted notorious experiments on rhesus monkeys to study maternal love, subjecting them to isolation and surrogate mothers, which raised significant ethical concerns.

Abstract

Harry Harlow, a psychologist at the University of Wisconsin, gained notoriety for his experiments on rhesus monkeys in the mid-20th century. These experiments aimed to understand the nature of maternal love and attachment, challenging the prevailing belief that these were merely responses to physical care. Harlow's methods included raising monkeys in partial or total isolation, which led to severe emotional distress, self-mutilation, and even death. He also introduced surrogate mothers made of wire or cloth to observe the monkeys' preference for comfort over food. The experiments revealed the importance of emotional bonding but were heavily criticized for their inhumane treatment of the animals. Harlow's own troubled childhood and his fascination with Freudian psychology may have influenced his research, which continues to provoke debate about the ethics of using animals in scientific studies, especially when it involves emotional and psychological trauma.

Opinions

  • The article suggests that Harlow's experiments were not only scientifically questionable but also morally reprehensible, given the emotional and physical harm inflicted on the monkeys.
  • The author implies that Harlow's personal history, particularly his relationship with his mother, may have been a driving force behind his research focus on maternal affection and deprivation.
  • There is an underlying criticism of the scientific community's past willingness to overlook ethical considerations in the pursuit of knowledge, especially regarding the use of non-human primates in research.
  • The article raises the question of whether the benefits of such research, which has informed our understanding of attachment and emotional development, can justify the suffering caused to the animals involved.
  • The author expresses a clear stance against the use of monkeys in research that causes distress and violates ethical guidelines, particularly the requirement for informed consent, which animals cannot provide.

Evil Scientist Who Tortured Monkeys For Notorious Fame

Uncovering the cruel insanity of Harry Harlow’s experiments.

Harry Harlow’s academic history is in relative obscurity for more than 20 years at the University of Wisconsin. His claim to fame, or rather a claim to notorious fame is the experiment he conducted with rhesus monkeys.

The roots of this experiment were in questioning what most scientists believed about maternal love; that it was merely an attachment infants felt for someone who fed, clothed, and protected them.

The Process

First, Harlow raised monkeys in either partial or total isolation. In partial isolation, the monkeys were kept in wire cages where they could hear, smell and feel other monkeys.

Monkeys kept in partial isolation showed signs of emotional distress and agitation as they were recorded to circle their cage, or even indulge in self-mutilation. For the study, some monkeys were even kept in isolation for 15 years.

While partial isolation absolutely breaks our hearts, total isolation was even more brutal, and in some cases even fatal. This involved rearing monkeys in the ‘pit of despair,’ a chamber designed to keep baby monkeys alone in the dark, completely away from any social interaction.

Once released from here, monkeys were recorded to demonstrate signs of emotional shock characterized by autistic rocking and clutching. While in one case, a monkey even died and its autopsy report showed the cause of death to be emotional anorexia.

Misleading monkeys with fake surrogate mothers

The monkeys in isolation were recorded to cling to their cloth diapers when nervous. This inspired the second part of Harlow’s experiment. He took baby monkeys and placed them with fake surrogate ‘mothers’ made from either wire or cloth. Each surrogate was alternately given a milk bottle as well.

Surprisingly, the baby monkeys preferred the cloth mother more, even if it was without the milk bottle. Harlow tested this with a peer group as well.

This research established how mothers and peer groups help an individual to adapt to society and its norms, we cannot help but wonder how inhumane the experiment was. And the extent to which Harlow basically tortured the rhesus monkeys is condemnable.

Who’s Harlow? Understanding the man behind the science

Harry Harlow, originally named Harry Israel, was born and grew up in Fairfield, Iowa. He lived with his parents and three brothers. Deborah Blum in ‘Love at goon park: Harry Harlow and the science of affection’ writes that Harlow was a bright but bored child. His early years were lonely and partially eclipsed by his brother Delmer’s illness.

Harlow’s idealogy was highly influenced by Sigmund Freud who was a neurologist and psychotherapist. Source: Wiki

Later, in an unfinished autobiography, Harry Harlow would describe life to be particularly dreary under the ministrations of a mother who was both cold and indifferent towards him. This led him to experience bouts of depression throughout his life.

A seemingly capable student, Harlow was able to attend Stanford University after passing an aptitude test in 1924. He worked directly with Calvin Perry Stone, an animal behaviorist, and Walter Richard Miles, a vision expert.

He was supervised by Lewis Terman, upon whose urging, Harry changed his name from Harry Israel to Harry Harlow in 1930 after writing his doctoral dissertation and earning the title of Ph.D. in Psychology from Stanford University.

Later, after graduating from Stanford, Harry Harlow secured a faculty job at the University of Wisconsin, Madison. It was here he conducted his controversial yet renowned experiment with baby rhesus monkeys.

Why Chose Monkeys in Scientific Research?

After scientists, the scientific community owes its success to the countless non-human primates that aid the research process. Especially, the macaque and marmoset species of monkeys that are made to participate in lab experiments.

From Yamamoto et al using chimpanzees to demonstrate targeted helping behavior and general altruism among monkeys to Harry Harlow experimenting with rhesus monkeys to conduct research regarding maternal love. These creatures have been kept in labs and used as specimens to aid the scientific process.

Similarly, in most studies and experiments aimed at researching cognitive abilities or emotional capabilities, we see monkeys bearing the brunt of being chosen as participants of the study. Why monkeys? One might ask.

This is because monkeys are most similar to humans, physiologically, anatomically, and biologically. Hence, they serve as the best prototype for humans when the results of research need to be relevant to humans.

However, that still goes against various ethical guidelines of scientific research. For one, monkeys are unable to provide informed consent. Secondly, the research might distress the animal as well.

This makes us question the morality behind using monkeys in research. Nevertheless, this article is aimed not at the morality of animals being used in research, although it is a point to ponder. Rather, this article is aimed at Harry Harlow and his incredibly insensitive experiment surrounding monkeys and how they respond to maternal love.

Manufacturing Maternal Love in Labs

The extent to which Harry Harlow went to prove the necessity of mothers being available emotionally as well seems like a manifestation of his subconscious desire to be closer to his own mother.

To elaborate further, Harry Harlow once said

‘I have no memory of maternal separation but I have lost maternal affection.’

And in his unfinished autobiography, he describes his mother as ‘cold’ and ‘indifferent’. Moreover, one of Harlow’s inspirations was Sigmund Freud, a notable psychologist who researched mother-child relationships.

What does this all point to? There is a clear pattern emerging pointing to one question: Harry Harlow tries to prove aggression as a result of an absence of maternal affection, is the procedure of this experiment, starving and basically killing innocent monkeys a result of that same aggression?

The aggression he had suppressed, that resulted from the bouts of loneliness and depression he has been said to have faced! Regardless of the motives, in times like these such experiments in my opinion are highly immoral! Thoughts?
