This is a pretty complicated topic that touches video games, gambling sites, social media algorithms, and marketing in general. It also touches fundamental philosophical questions like the existence of free will.
We have lots of established law on which sort of “mind tricks” are fair play and which aren’t, but we have not advanced those laws to keep pace with the science. Currently, lying is really the only thing off limits and is covered by fraud statutes. We also have some limits on marketing to children. But one could argue that there are several “persuasion” tactics that can be just as effective as outright lies in manipulating the behavior of others. In fact, licensed therapists are ethically barred from using these tactics, yet we allow salesmen, marketers, etc to use them at will.
I don’t really have an opinion on this lawsuit, nor do I feel qualified to offer a solution. But let me give you an example of how the human mind works which underpins addiction to gambling.
Dopamine is a signaling molecule that regulates a lot of our reward responses. If I find honey in a honeycomb, dopamine gets released and now I am more likely to seek out honeycombs in the future. You can see how this is evolutionarily beneficial. Dopamine release reinforces behavior that increases survival. But let’s say that only about 1/3 of all honeycombs have honey. Now I have a lower chance at a reward, so does that mean the dopamine release is likewise diminished? No, the opposite is true. Dopamine release skyrockets. Evolutionarily this makes sense, we do not want to miss out on a reward simply because the probability is diminished, so the high dopamine release counterbalances the diminished probability such that reward seeking behavior is reinforced so long as the probability of reward is reasonable (it peaks at about 1/4). In fact, dopamine is released even when the honeycomb has no honey. You can draw a direct line between this physical phenomenon and gambling addiction. What people don’t appreciate is that this physiological response is very similar to addictive drugs in effectiveness. It can be hard to acknowledge that one of the reasons you are not a gambling addict is simply that you didn’t start gambling to begin with, not that you are somehow superior to those that are addicted.
We have lots of behavioral quirks like this that can be exploited. At what point does this manipulation cross the line? That is a hard question. For me, gacha games cross that line. But if we want to enact meaningful regulations we need to acknowledge that these mind exploits exist and confront the fact that free will may not be as free as we hope.
I have obviously simplified the role of dopamine in the brain to make it more digestible, but you are dead wrong about dopamine’s role in intermittent reward and the link to gambling addiction. It has a very strong influence on behavior. Like many aspects of human behavior, the effect is not an on-off switch to enable gambling addiction. We have lots of things going on in our head that are, at times, working against each other as far as behavior is concerned. It is more like an analog adjustment that “pushes” toward a specific behavior much harder than it otherwise would. And this effect is just as powerful as addictive chemicals in potency.
