DESCRIPTION:Research on collective decisions has mainly focused on whether
  they are better or worse than individual decisions\, but rarely on the mo
 tives that drive individuals to engage in group decisions. Besides improvi
 ng accuracy\, an important and less explored motive for individuals joinin
 g collectives is to share responsibility for decision outcomes. Here I wil
 l defend this view by proposing a novel framework on the motives driving i
 ndividuals to join groups and argue that collective decisions help protect
  from negative outcomes by reducing stress\, regret and punishment. To emp
 irically support this claim\, I will present results from studies I have c
 onducted addressing whether: 1) individuals feel less responsible when mak
 ing decisions in groups 2) individuals join groups to anticipate and exper
 ience less regret during risky decision-making 3) norm violations and thei
 r punishments differ in individual vs collective decisions. This approach 
 to collective decision-making tackles issues of regret\, punishment and re
 sponsibility\, and therefore has implications across a wide range of socie
 tal domains\, including political and medical decision-making as well as c
 riminal justice.\n\n_Marwa El Zein is a Sir Henry Wellcome Trust research 
 fellow at the Institute of Cognitive Neuroscience\, University College Lon
 don. She is currently investigating the cognitive and neural mechanisms un
 derlying human collective decision-making. After an undergraduate degree i
 n biology and a master degree in cognitive sciences in Paris\, she complet
 ed her PhD in cognitive neuroscience at Ecole Normale Supérieure (Paris) 
 on the neural mechanisms of contextual influences during perceptual decisi
 ons on facial emotions._\n
