(*Not sure if the theory of male vs female navigational styles is still current.)
LOL, I don't know about "the theory of male vs. female navigational styles" might be.
But there's no "theory" about gender differences where three-dimensional spatial skills are concerned. Males,
as a group, significantly outperform females,
as a group, in the ability to navigate in three dimensional space. Individuals of course vary, so for example you might find individual men with poor or low average skills in this area, while individual women can be found who are very superior. If you graph the scores of a random population of males, and superimpose the curved line that results over a similar line representing the scores of females, you will find there are many more men at the upper (right hand) end of the distribution, and many more women in the lower and average (left side) of the distribution.
Group averages tell us nothing about individuals, though. You are probably a person whose 3-D spatial skills are high for a female, possibly above average even for a male, while a guy who was a buddy of mine at university had to be one of the worst ever of any gender. We were driving somewhere,and, get this, he made a U-turn and didn't have any awareness that he was now going in the opposite direction. This became clear in the next few minutes. I was stunned, but incredulous. This guy was very smart but I made a mental note to self, Don't go in a car with him again unless you (meaning, myself) are driving!
There are more air traffic controllers who are men, for this basic reason, apart from any discrimination, which may also play a role. But women get their own back by (as a group) beating the guys in verbal reasoning, language aptitudes of various kinds, and several types of memory.
Here's a paper on the topic:

I say
vive les differences.
