And yet, your wiki includes this further wiki link:
https://en.wikipedia.org/wiki/Bystander_effect
The mere beginning of the first section starts "The bystander effect was first demonstrated in the laboratory by John Darley and Bibb Latané in 1968 after they became interested in the topic following the murder of Kitty Genovese in 1964.[1] These researchers launched a series of experiment
s that resulted in one of the strongest and most replicable effects in social psychology.In a typical experiment, the participant is either alone or among a group of other participants or confederates. An emergency situation is staged and researchers measure how long it takes the participants to intervene, if they intervene. These experiments have found that the presence of others inhibits helping, often by a large margin.[2] For example, Bibb Latané and Judith Rodin (1969) staged an experiment around a woman in distress. 70 percent of the people alone called out or went to help the woman after they believed she had fallen and was hurt, but when there were other people in the room only 40 percent offered help."
My point stands regardless of whether the NYT initially exagerrated the article and corrected this only on April 4, 2016, in an obituary for the murderer in the "NY/region" section....
