In December of last year the New York Post published images of a man about to be killed by a train while several bystanders did little to help him. Numerous studies have provided evidence that people are less likely to help when in groups, a phenomenon known as the "bystander effect." Those studies examined situations where only one person was needed to take action to help another. A University of Missouri anthropologist recently found that even when multiple individuals can contribute to a common cause, the presence of others reduces an individual's likelihood of helping. This research has numerous applications, including possibly guiding the fundraising strategies of charitable organizations. http://medicalxpress.com/news/2013-04-individual-donation-amounts-givers-groups.html Psychology & Psychiatry Thu, 11 Apr 2013 13:01:27 EST news284904080 A compound that stimulates the production of a tumor-fighting protein may improve the usefulness of the protein in cancer therapy, according to a team of researchers. http://medicalxpress.com/news/2013-02-compound-tumor-fighting-protein-cancer-therapy.html Cancer Wed, 06 Feb 2013 15:19:06 EST news279386339 The bystander effect is well-known in behavioural psychology and suggests that the more people who witnessing a violent emergency the less likely it is that someone will intervene.
