How do beings' preferences shift?

Beings' preferences shift as they gain more knowledge, options, and self-awareness. According to Eliezer Yudkowsky, as beings become smarter, they better understand their desires and options, leading to shifts in preferences. The process involves internal conflicts and adjustments based on new information and experiences. For example, humans might have different attitudes towards actions like killing, depending on their circumstances and the options available to them. This change continues up to a point where the system crystallizes unless further changes are intentionally sought 1.
