I will agree that members of both sexes fall prey to the “I am always right!” fallacy. They may do it for different reasons (e.g. some may just assume they are naturally superior, while others may get emotionally invested in their positions). Those reasons may or may not be gender aligned as well. I certainly don’t have the data to determine that.
I will posit that one source of the meme is the gender roles of the past. In the ideal nuclear family of the 50s and 60s with the stay-at-home mother, the assumption a strict division of spheres. In that situation, with the only control a wife had being how she kept house, I can see the need to let the wife have her way at home in almost all things.
The same is probably true in most healthy relationships today, just hopefully with less socially imposed spheres of interest. For example, in my marriage I care a lot less about how things look than my wife does. When it comes to picking the paint color, I may make suggestions or give opinions, but in the end I let her make the choice because she cares more and thinks about it more. On the other hand when it came time to buy her a new laptop, even though she is the one using it, I picked it out based on what she wanted to use it for. In the final analysis she cared enough about paint to know that bedrooms should be eggshell and kitchens should be semigloss and I care about computers enough to know if a dedicated graphics accelerator is worth an extra $200 on a machine that will mostly be used to surf the net and watch youtube videos.

She said something like, “Well, you were getting upset too.” When she was rummaging around, I went back in the house to stay out of the line of fire. She may have interpreted that as a hostile act, though I saw it as self-preservation. I didn’t say anything, I just got out of the way. Based on my telling, I’m sure that different people imagine it playing out in different ways. I’ll just say that I was calm and she was agitated and I was trying not to make her more agitated.
