Psychology as we know it is a relatively young science, but since its inception it has helped us to gain a greater understanding of ourselves and our interactions with the world. Many psychological experiments have been valid and ethical, allowing researchers to make new treatments and therapies available, and giving other insights into our motivations and actions. Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession. Here are ten psychological experiments that spiraled out of control.
10. Stanford Prison Experiment

| Prisoners and guards |
In 1971, social psychologist Philip Zimbardo set out to interrogate the ways in which people conform to social roles, using a group of male college students to take part in a two-week-long experiment in which they would live as prisoners and guards in a mock prison. However, having selected his test subjects, Zimbardo assigned them their roles without their knowledge, unexpectedly arresting the "prisoners" outside their own homes. The results were disturbing. Ordinary college students turned into viciously sadistic guards or spineless (and increasingly distraught) prisoners, becoming deeply enmeshed within the roles they were playing. After just six days, the distressing reality of this "prison" forced Zimbardo to prematurely end the experiment.

Wendell Johnson, of the University of Iowa, who was behind the study |
In this study, conducted in 1939, 22 orphaned children, 10 with stutters, were separated equally into two groups: one with a speech therapist who conducted "positive" therapy by praising the children’s progress and fluency of speech; the other with a speech therapist who openly chastised the children for the slightest mistake. The results showed that the children who had received negative responses were badly affected in terms of their psychological health. Yet more bad news was to come as it was later revealed that some of the children who had previously been unaffected developed speech problems following the experiment. In 2007, six of the orphan children were awarded $925,000 in compensation for emotional damage that the six-month-study had left them with.
8. MK-ULTRA

The CIA performed many unethical experiments into mind control and psychology under the banner of project MK-ULTRA during the 50s and 60s. Theodore Kaczynski, otherwise known as the Unabomber, is reported to have been a test subject in the CIA's disturbing experiments, which may have contributed to his mental instability. In another case, the administration of LSD to US Army biological weapons expert Frank Olson is thought to have sparked a crisis of conscience, inspiring him to tell the world about his research. Instead, Olson is said to have committed suicide, jumping from a thirteenth-story hotel room window, although there is strong evidence that he was murdered. This doesn't even touch on the long-term psychological damage other test subjects are likely to have suffered.
7. Elephant on LSD

| The Milgram Experiment underway |
In 1963, in the wake of the atrocities of the Holocaust, Stanley Milgram set out to test the hypothesis that there was something special about the German people that had allowed them to participate in genocide. Under the pretense of an experiment into human learning, Milgram asked normal members of the public to ask questions to a man attached to an electric-shock generator and shock him in increasing measure when he answered incorrectly. The man was an actor, the shocks fake; but the participants didn’t know this. The terrifying part? People overwhelmingly obeyed the commands of the experimenter, even when the man screamed in apparent agony and begged for mercy. A little evil in all of us, perhaps?

4. Pit of Despair

| A rhesus monkey infant in one of Harlow's isolation chambers |
Psychologist Harry Harlow was obsessed with the concept of love, but rather than writing poems or love songs, he performed sick, twisted experiments on monkeys during the 1970s. One of his experiments revolved around confining the monkeys in total isolation in an apparatus he called the "well of despair” (a featureless, empty chamber depriving the animal of any stimulus or socialization) — which resulted in his subjects going insane and even starving themselves to death in two cases. Harlow ignored the criticism of his colleagues, and is quoted as saying, “How could you love monkeys?” The last laugh was on him, however, as his horrific treatment of his subjects is acknowledged as being a driving force behind the development of the animal rights movement and the end of such cruel experiments.
3. The Third Wave
2. Homosexual Aversion Therapy
1. David Reimer
In 1966, when David Reimer was 8 months old, his circumcision was botched and he lost his penis to burns. Psychologist John Money suggested that baby David be given a sex change. The parents agreed, but what they didn’t know was that Money secretly wanted to use David as part of an experiment to prove his views that gender identity was not inborn, but rather determined by nature and upbringing. David was renamed Brenda, surgically altered to have a vagina, and given hormonal supplements — but tragically the experiment backfired. "Brenda" acted like a stereotypical boy throughout childhood, and the Reimer family began to fall apart. At 14, Brenda was told the truth, and decided to go back to being David. He committed suicide at the age of 38.
