Predisposition toward organizing information in a hierarchical manner? I understand someone why we like hierarchical social structures today.  They are present across virtually all cultures and we've used them for a very long time.

However, it appears we also gravitate toward organizing things in hierarchies as well, not just people.  When we study topics, we draw diagrams of hierarchies.  When we write textbooks, we subdivide information into ranges of topics and them smaller ranges, and then the individual concepts themselves.  We put our paperwork in folders, in filing cabinets, which are arranged in shelves, which are arranged in rows of shelves, and so on...

Recently we've spent more time exploring other structures like networks with nodes, but our default still seems to be hierarchies.

It's not just organizations and governments that we organize this way, but also information.  Why is this?

Regarding the utility of hierarchies in organization information, binary search trees in computer science allow finding indexed information very quickly (Adamchik, 2009).  However it is common knowledge that we have been organizing information hierarchically long before the advent of computer science.  So did we realize this intuitively?

Perhaps this predisposition bleeds over in some way from social hierarchies?  Could our other predisposition to see human intention in inanimate objects have led us to use the same structure for information (Coolidge, 2016)?

This is not out of desire, it is out of necessity of abiding a feature of information and knowledge itself. Quite frankly, this goes into a bit of data science and information theory (I personally learned of this through data visualization. Nonetheless, I still think it is a relevant question).

According to Richard Wurman in his book, Information Anxiety, “information may be infinite, however… the organization [or structuring] of information is finite.” Furthermore, “Each vantage point, each mode of organization will create a new structure. And each new structure will enable you to see a different meaning, acting as a new method of classification from which the whole can be grasped and understood.”

The three main ways of organizing information are as follows (please note that those within parenthesis are my personal examples, the rest are more main/established ones):  


Location  
Categorical
a. (similarity/relatedness)
b. (problem/solution)
c. (cause/effect)
Hierarchical
a. Alphabetical
b. Time
c. (deductive/inductive order)
d. (importance)
e. (simplicity/complexity)  


In relevance to hierarchical information and psychology though, it is worthwhile to note that both foundations of language and logic are found through the alphabetical category. These, in turn, are fundamental features of the human mind and are, in large part, also means through which the mind makes connections. Also, tendencies towards hierarchical information could also be explained through using time as an anchor to which to describe things in relation to such as the past, present, and future.
