One of the reasons why dating advice is a scam almost all of the time is the refusal to admit that most women are unsuitable for dating (and relationships). If the purveyors of dating advice were honest, then they would tell men not to date most women. While you can find lists of “women to avoid” on the internet and elsewhere, when it comes to brass tacks in dating advice, those women don’t exist. (Or their situations are somehow a man’s fault so you should still date them.)
On average women are significantly more likely to have STDs, debt, a higher number of sex partners, etc., and the psychological problems associated with them than the average man is. (This is due to the effects of the 80/20 rule.) For the average man, most women are a losing proposition even if dating advice had a sure fire way to get them into bed/make them your girlfriend. This is why many men have decided to go their own way/go ghost/opt out. The value proposition for most women simply isn’t there. Nearly all dating advice refuses to recognize this sobering fact.
Why do purveyors of dating advice refuse to admit the state of most women? The first reason is financial. There is no money in it. Because telling men not to date (and by extension not get into relationships and marriages with) most women doesn’t require books, DVDs, and seminars. It only requires a paragraph of text which can’t be sold. The second reason is ideological. Dating advice is used as a gateway into tricking men into various ideologies from feminism to red pill “Christianity”. All of these ideologies are similar in that they don’t have men’s best interests in mind and that they are gynocentric. A statement of fact such as most women are unsuitable for dating (and relationships and marriage) can not be used to trick men into gynocentric ideologies that are bad for them. It directly contradicts their ideologies and is an admission that their ideologies are nothing but lies.
