Behavioral economics can explain some things, but it's hard to explain a lot of the underlying processes that generate these decisions, much less some of these unconscious things that we don't have a handle on at all.

You can imagine over very long timescales, perhaps far beyond the multi-decade time scale, we might be able to ask very deep questions about why we feel the way we feel about things, or why we think of ourselves in certain ways - questions that have been in the realm of psychology and philosophy but have been very difficult to get a firm mechanistic laws-of-physics grasp on.
