Why do your mom's dating advices suck?

Game guides will usually mention something along the lines of "do the opposite of your mom's dating advices, like be nice to her, buy her flowers, etc". Now why would mothers give bad advice to their sons? My theory so far is that it's another mismatch: sons raised by their mothers could be a recent phenomenon, so having a different attitude towards your son than towards other males (shit test them) would not provide a fitness advantage.
