"You're doing it wrong. If you do it right, the response from impulsive women will be to "prove" that they can eat the marshmallow AND have sex with you."
That assumes you're still young enough that random sex from impulsive women is your goal.
"Also the marshmallow test is pretty flawed when used with anyone who has experience. Doesn't matter how much impulse control you have, if promises of delayed gratification have in the past been consistently broken and led to no gratification."
That's actually just what it finds - children from stable homes are significantly more likely to delay gratification because from birth they've learned to expect long term planning to succeed. Children from single mothers / broken homes have learned from birth that you need to take pleasures while you can because there is no guarantee that promises in the future are reliable.
