I guess I just disagree with this.
Most progressive players wager more after losses. Casino's LOVE progressive players.
Players that "chase", bet more after a loss or series of losses, trying to win their money back. Casino's LOVE players that chase losses.
The basic premise is chips already on the felt as opposed to in your stack. After a win you already have double the chips already on the felt, more than double in the case of blackjacks, double downs and splits. But conversely, after a loss there are no chips remaining on the felt. A player
must go to his stack, so it is not unusual to play a different amount. Of course there are limitations. You can't throw out $500 after losing a $25 bet regardless of count.
One of my pet peeves is a push. It is very unnatural to bet anything other than the same amount.
