in my experience the shorter the code the harder it is to understand because as you said developers are problem solvers so when you find a unique way to solve an issue most of the time the solution would be short and fast especially when you solve an algorithm for example if i said write a code that sums numbers from 1 -> 1m most developers may write a loop but this problem can be solved with just one line with this equation and if i see something like this without a comment i would freak out.

Sometime fastest code wear strange habits. In such case i prefer writing 50 lines of comment, than rewriting the optimal code.
