I was trying to find all symbolic links in /usr/lib and use file on the first entry in the list, which I delimited with head -n 1.

Why does find /usr/lib -maxdepth 1 -type l | file $(head -n 1) work but find /usr/lib -maxdepth 1 -type l | head -n 1 | file does not?

It complains that I am not using file correctly. Probably because it lacks an argument, but - programmatically/syntactically - why can't file grab it's argument from the pipe?

It's not like it, it's exactly it. The output from find is text, - means read stdin, so file told you the text in stdin was text. You'll have to see if it takes a list of files as an option, otherwise just use a for loop.
