Plus the mandatory comment by the woman psychologist:
Sung Young-shin, a psychologist at Korea University, says, she is concerned that the doenjang-nyeo controversy will rekindle old views of all women who care about their appearance as dim. "Male and female students in their 20s, who need a more mature perspective on each other, have instead been galvanized along gender lines by this black-and-white logic,” she adds. “Perpetuating these misconceptions will be bad for both sides."
If someone spends an inordinate amount of money, time and attention on appearance, that says something about their character--ditto if they spend an unreasonable amount of money on necessities. It's not a misconception, it's an inference. Gee-whiz, can't stand psychologists who take it upon themselves to be social engineers.
