Oh, this is very brilliant of you
Thanks but it has nothing to do with me. The information is already out there, even the contextualization of this bias.
I don't understand this. If losing money is painful for you, why do you continue? Sounds irrational to me.
Start playing in a casino only if you are okay with losing what you have allocated for the game. You shouldn't even start otherwise. Also, I disagree with the notion associated with loss aversion that "the pain of losing $100 is often far greater than the joy gained in finding the same amount". How can you compare pain and joy? They're entirely different experiences.
Losing money is painful to almost everyone whether it happens within or outside your pre ascribed bank roll. The question that why people gamble has various answers in psychology (dopamine, adrenaline etc.). Here we are discussing one of the major factors which can lead a fun and entertaining [even money making {poker, sports etc.}] activity towards an addiction.
Regarding your question about methodology, you will find it quite helpful;
https://insidebe.com/articles/loss-aversion/ The man has 300 dollars. He lost $100. According to these scientific studies, should he bet on the last 200 dollars, despite the risk of starving to death? How did it happen that the premise (survival is more important than satiety) led to a consequence (to win at all costs) that contradicts the premise?
We have plenty of cases where people gamble away their rent money or their paycheck for entire month. A brutal one was
Father sold his 11 month old baby to fund his gambling addiction.
The premise was that we hate the feeling of loss that is why we tend to chase losses in order to get rid of the feeling. To avoid this inner confrontation we take bigger risk which sometime even threaten the survival. These are impulse based decisions with little thoughts about planned and safe long term future. .
