One of the reason why many gamblers naturally chase after their lose is due to one thing that is built into every game known as the "near miss effect", after every loss, a near miss effect makes our brain believe that a win is very close, and this automatically makes the player to keep playing and playing, even while he or she is losing, his or her brain convinces itself that a jackpot is just around the corner, this makes the player keep playing until he or she discovers that his or her bankroll is empty, this is when anger and regret usually sets in, you begin to feel like you were not really yourself all that time you were gambling, like you were hypnotized or something, and you only regained consciousness of yourself when you have already gambled all your money away.
That is exactly the reason why people gamble at lost. When people have that mindset that they gonna win someday somehow and they end up being trapped in hallucination or illusion of the impossibility. I know some guys who usually gamble endlessly with the hope of wining big anytime soon, yet those words end up being a. Empty hope. After losing for several decades there mindset where changed by reducing the level at which they gamble why some hasn't changed or stopped. I believe in your statement which says that people Chase loses due to the effect known as "near miss effect" and U find that to be true.
