Men (about 80% of them, I’d say)tend to think about directions from an overhead map perspective and want to give and receive directions in that form. 80% of women prefer the landmark scheme Christine notes above. It’s probably a brain spatial-memory thing. Men do better giving directions to men, women to women.
As a consequence, men are more likely to get the distance wrong (overhead map visualising underestimates), women to get the direction wrong (roads wind and turn). That’s a tough choice, eh?
This also accounts for many of the male-female navigation arguments, by the way. They look at maps and directions differently.
