Arie W. Kruglanski (born in 1939) is a social psychologist known for his work on goal systems, regulatory mode, and cognitive closure.
These theories inspired empirical research in various domains of psychology and have led to development of scales that measure the need for cognitive closure (with Donna Webster, 1994) and regulatory modes of locomotion and assessment (with Tory Higgins, 2000).
Among others, Kruglanski and his students studied captive Liberation Tigers of Tamil Eelam after the defeat of that South Asian terror group, finding that de-radicalization is possible with a systematic process involving the 3N framework.
Among the projects the Kruglanski lab is pursuing are violent extremism, political activism, the quest for significance, coping with uncertainty, and closed-mindedness.
Their research uses a variety of methods, including lab experiments, neuroscience techniques, computer modeling, text analyses, and surveys.
