Think of this analogy: every person in the world flips a fair coin. Those who flip tail, stop flipping coins. Those who flip head, flip one more time, and so on

Think of this analogy: every person in the world flips a fair coin. Those who flip tail, stop flipping coins. Those who flip head, flip one more time, and so on.
In expectation, the overall number of heads and tails will be the same - if you look at the system from the outside, it's just a bunch of independent flips with fair coins, the decisions of the participants have no effect.
- kamaal 12y agoYes, but you are making a big assumption that it will be a fair coin. In the real world. There are other factors that contribute to gender imbalance(Infanticide, foeticide, mortality etc). Plus also note that once the gender balance goes out of balance it continues get worse with every iteration. So this basically works like algorithm which is continually trying to increase the count of M's above F's.
