Why do we embrace tradition, especially in the west?

[Ostronomos]

Is it a character flaw? Or does the need to embrace tradition run deeper?

Upon self-analysis. Can one say that it is purely psychological? Who decides why we do the things we do? Is it the subconscious?

Traditions can be considered the ritualistic habits of one's family, culture, etc. Many if not most may seem otiose or recreational -- serving little practical function, but still potentially imbued with importance (including the commemorative role). Engaging in customs and expected routines with the rest is an indication and avowing that one still belongs to and shares some part with the group identity, and allegiance.  Reciprocal activity contributes to mutual acceptance and cohesion.

No society or organization survives long if the behaviors of its members and interactions between them are either random or constantly innovative. (With respect to the latter, each individual introduces new patterns and order, but they are rarely repeated and copied/picked-up by others. Incoordination and chaos thus reign. Absolute "freedom" is not useful -- some significant degree of conformity and monotonous regularity by the components is necessary.)
