why does the doubling your money strategy not work in gambling?
The idea where you will keep doubling your money whenever you lose a bet. For example if a player starts at $1 and loses four bets in a row, winning on the fifth, he will have lost $1+$2+$4+$8 = $15 on the four losing bets and won $16 on the fifth bet. The losses were covered and he had a profit of $1.

if most youtube ads can be skipped after 5 seconds, why don't advertisers start making 5 second ads?
This goes for all online ads really. It has been shown that less intrusive ads (Google text ads, for example) are often more effective than large annoying things that will just get adblocked anyways. I understand that it's not widespread, but why don't I see this at all?
