The use of the brain’s weaknesses by casinos is something I am glad you described here. When you see numbers like the percentage of near-misses programmed in to keep people trying, you start to see a simple slot machine as an item containing years of effort in extracting funds from customers in seemingly innocent way. The amount of experience and fine-tuning that is present in the code of current slot machines completely overwhelms any sense of them being transparent like an arcade pinball machine, where you can see the ball as it travels. Information like this is the kind that casinos are not interested in having spread around, as the deceptive environment they are looking to profit from can only be maintained if people feel like they win and lose based on normal circumstances, and not due to an evolution of alterations made to take advantage of their vulnerable mental qualities.
