There's the problem of how you define readability. Many people evaluate it in a per line basis, rather than comparing pieces of code that achieve equivalent functionality. Measuring readability like this is unfair to languages that favor terseness beyond that of natural language.

In order to understand good Lisp code you need to learn new tools for expressing procedural concepts. Tools that are better, for that task, than natural language. Most people would think there is no such thing. Most people will always stick to whatever feels more intuitive at each stage of their formation as programmers. This is often a handicap to learning to think in more powerful ways.
