It was initially reported in 1964 that Kitty Genovese repeatedly screamed as she was attacked, then murdered by Winston Mosely in front of her apartment building in New York but it was reported that none of the 38 witnesses came to her aid.  Although upon later investigation, the number of witnesses and their inactivity may not be entirely true, it shocked the nation and it led to much social psychology research on the bystander effect and the likelihood of people intervening in an emergency.

When others are around, people are less likely to intervene due to a diffusion of responsibility. Each person present at an emergency may assume others will intervene leaving others to accept less responsibility for helping. Studies have shown that in emergency situations 75% of people who helped were alone compared to 53 % who were in the presence of others. Act first. Don’t wait for others to intervene.

So how can you increase your chances of getting help if you are ever in danger? First, make your need clear. Second, select a specific person to help you. This will overcome the major obstacles that prevent others from helping.

That’s your Florida Tech Psychology Science Minute. I’m Dr. Sarah Arnett.

Definitions:

Bystander effect: or Genovese syndrome is a social psychological phenomenon that refers to cases where individuals do not offer help in an emergency situation when other people are present (Wikipedia, downloaded, 1/8/11).

Diffusion of responsibility is a social phenomenon that tends to occur in groups of people above a certain critical size when responsibility is not explicitly assigned. This phenomenon rarely ever occurs in small groups.  In tests, when in groups of three or fewer, everyone in the group took action. This is as opposed to when in groups of over ten, where in almost every test no one took action. This mindset can be seen in the phrase “No one raindrop thinks it caused the flood”.  (Wikipedia, downloaded, 1/8/11).
