Abstract	There is ample evidence for in-group bias in attention and perception and the corresponding neural correlates. Yet, little is known about how the changes in intrinsic functional connectivity relates to in-group bias. To shed some light on this issue, we combined a fMRI experiment with task-free resting states over three sequences: A perceptual matching task with stimuli associated to inand out-groups and two rest sequences, before and after the task. Using seeds based on the activations in fMRI task, we measured the differences in preand post-task intrinsic functional connectivity in a group of football fans. Our results revealed that compared to pretask, post-task functional connectivity increased between the left anterior insula (AI) and the left inferior frontal gyrus (IFG) and this was positively correlated with the ingroup bias in behaviour. In contrast, post-task functional connectivity was significantly weaker between the left AI and the left dorsolateral prefrontal cortex (DLPFC), but this was unrelated to behavioural biases. These results suggest that intrinsic functional connectivity between the AI and IFG might explain the possible mechanisms in-group biases in attention. This framework provides novel insights into the neural dynamics underlying in-group biases in the context of real world rivalry.
