I promise it is not always the personality that decides. Personally, I see far more people for whom the physical stuff is true rather than the personality stuff. I'm not social or outgoing - if anything I've only become so because I started taking part in IG and Gender Dreaming - and I got my girl AFTER that.
There is also what the husband brings to the table, their frequency of intercourse, and sheer luck to consider. All these things play a part, as does their life history that you can't even see by looking at them.
I believe in swaying because firstly it makes sense that there would be some mechanism that could help select the gender of offspring that had the best shot to survive to pass down genes to future generations. Secondly, because both in studies and our results here, swaying seems to work. We have studies (good studies!) that show things like maternal diet, a woman's muscle mass, her BMI, smoking, jogging/biking for DH have different gender ratios. We have gotten the desired results for both pink and blue every year the site has existed and the odds of that happening if gender really was a coin flip are astronomical

Swaying is not 100% or close to it, but for those of us who have had 3,4,5 of the same gender already and know in our guts we are not going into conceiving with anything like a 50-50 chance, for me I would have happily taken the 50-50! Even if swaying could only get me to 50%, it was better than the 100% boys I'd had before, LOL. So you guys can't go into it expecting a guarantee, but it does help raise your chances or we'd not see the results we are seeing.
I'm not here to talk you into anything you don't want to do. If you don't believe in swaying, don't sway. But I believe in it and I'm happy to help anyone who wants my help, however I can. :)
