perplex

This verb describes a state of mental entanglement where a person is unable to grasp a concept due to its contradictory or overly intricate nature. It carries a stronger sense of frustration and intellectual blockage than simple confusion, suggesting a puzzle that resists a solution. In professional or academic settings, it often describes the reaction to unexpected data or paradoxical evidence. It is typically used in formal or semi-formal registers to describe a cognitive struggle rather than a momentary lapse in understanding.
