Beliefs and memories from Inside Out 2, our sense of self

In the movie, [*“Inside Out 2”*](https://en.wikipedia.org/wiki/Inside_Out_2) , it was revealed that Riley’s memories contributed to her belief system and sense of self. This is pretty much in line with existing research into [how memory define our beliefs and identity](https://journals.sagepub.com/doi/10.1177/23727322231220258) . However, it also begs a few questions. First, how do we prevent wrong memories from forming that create unskilful beliefs or views? Or correct our interpretation of such memories if they are already formed? I am especially intrigued by wrong beliefs (or views) that are formed from bad memories. Like in Riley’s case, *“I’m not good enough”* partly from her anxiety and self-critique but triggered by recalled images of how she almost failed her hockey team. (Of course, there are skilful/wholesome beliefs too like, *“I’m a good person”* when Riley recalled images of making all sorts of friends while growing up). Second, it appears that extremism, intolerance and prejudices arise from wrong beliefs. Yet, tapping on our reservoir of diverse memories and beliefs can pull us out of difficult situations. Such as when Riley was suffering from a panic attack in the penalty box, drawing on all her memories, experiences and beliefs to restore a correct sense of herself. This is possible because she had a myriad and diverse memories/experiences growing up. So, does this mean that having a variegated memory/experience from interacting with various different types of people, beliefs, views and ideologies would be helpful in reducing extremism, intolerance and prejudices? Does this mean that Buddhists should not associate solely with Buddhists and should expose themselves to other religious teachings like the Bible, Koran, Vedas and so on. Ditto for Christians, Muslims, Hindus and so on? (Note: the Buddha himself was exposed to a wide variety of ideologies/belief systems in his search for liberation). Third, can the Dharma be extreme or lead to extreme, intolerant and prejudiced behaviour? Or does it instead have a moderating effect? Lastly, it seems that the process of memory consists of [3 stages: encoding, storage and retrieval](https://bokcenter.harvard.edu/how-memory-works) . I suspect mindfulness practice can help with the storage and retrieval stage, is this correct? Are there any Buddhist practices that can help with the encoding stage? As I suspect existing biases/prejudices could prevent objective encoding. Similarly, wrong interpretation of our memories could also cause issues as research into [cognitive and memory biases](https://en.wikipedia.org/wiki/List_of_cognitive_biases#Memory_biases) indicated. All these could result in errors in decision making, wrong views/beliefs and ultimately suffering. Is there any Buddhist practice to overcome biased interpretation?
