On March 13, 1964, a woman named Catherine "Kitty" Genovese was walking back to her apartment in Queens, New York, at 3:00 a.m. when she was impaled on a death by a serial killer. According to reports, the attack lasted about 30 minutes. During the attack, Kitty Genovese screamed for help numerous times. The killer left the scene when he attracted the attention of a neighbor. Ten minutes later, the killer returned to the scene and killed Genovese. It emerged that 38 people witnessed the attack and murder, but all thirty-eight did not report the incident until after the murder. This ordeal attracted the attention of many people, including scientists and psychologists, who wanted to understand why this happened. Subsequently, the events published on the news turned out to be false. It seemed that the news also suffered from the bystander effect, because their information did not contribute to the real facts. There were no 38 witnesses to the crime, but several had heard the screams and some calls had been made to the police during the attack. But there was still talk of something that affected people's minds during emergency situations. This phenomenon has become known as the bystander effect. There have been several cases quite similar to the Genoese one. Like the Genovese case, these events attracted the attention of many scientists and even the news spoke of "apathy". Is the bystander effect real? My hypothesis is that the bystander effect is, in fact, a real everyday occurrence that limits the help people offer. This is due to the number of spectators present during a given situation. The bystander effect is the social psychological idea that refers to cases in which...... half of the article ......although the researchers weren't looking for it, the results represent ideas that can help the bystander effect in a situation. Smaller numbers increase the success rate when dealing with an emergency. The victim, if cohesive, actually plays an important role in causing the bystander effect as well. When a victim is unable to communicate verbally with bystanders, the possibility of help is diminished. If a victim is able to communicate, the help provided may be more effective. This is because it can help break the diffusion of responsibility. A victim looking a passerby directly in the eye may even trigger a quicker reaction in them. These are all ideas that psychologists still study today, and many even consider learning about this phenomenon a requirement. The bystander effect plays a key role in today's society. More and more people ignore a person in difficulty.
