The classical question of determining which varieties are rational has led to a huge amount of interest and activity. On the other hand, one can take on a complementary perspective: Given a smooth projective variety whose nonrationality is known, how far is it from being rational? I will explain recent progress in this direction for complete intersections in projective space.
