1. marriage statistics don't lie.
2. people don't lie randomly but there is a pattern to their lies and there are things they're more and less likely to lie about.
Pretty much all data indicates that the vast majority of relationships involves a five year gap at max - and in the recent years, age gaps have actually shrunk and are still shrinking. People are more likely to date within their own age range, even more so on dating apps, where people screen each other for such numbers before even entertaining the thought of a relationship. Most young women filter for age even more so than they filter for height or income. While you will find outliers of large age gaps (80 yo billionaire marries his 20 yo girlfriend, Leonardo DiCaprio, etc.) they are so rare that they don't affect the general tendency.
