The survey by Norwegian University of Science and Technology (NTNU) showed that women trail men in their knowledge of the political field.

"We actually found the opposite to what we were expecting," said NTNU professor Toril Aalberg, adding that it seemed that countries with the most gender parity had the worst score for men and women taking an equal interest in politics.
