Research
While in New York, Darley began the research that defined his career. After hearing of the tragic case of Kitty Genovese, he was inspired to explore why people are less likely to intervene when there are other witnesses present, a phenomenon is the “Bystander effect”. With collaborator, Bibb Latané from Columbia University, Darley developed and conducted experiments to explore the bystander effect and understand the circumstances that create it.
From the mid-1970s to the mid-1980s Darley turned his attention to pioneering efforts aimed at applying psychology to engineering and energy conservation. He worked with colleagues on how behavioral ideas can be used in energy conservation to better the environment and economy.
At the end of his career, Darley's focus changed to the average person's conceptions of law and the legal system. This interest of his turned into his main line of research. Darley saw the current reformatory strategy used in prison system as a poor one, he wanted to develop a psychology based reform strategy.
