Reports/research about legalese texts

I'm looking for any reports or user researches done related to legalese text in software. Apart from curiosity I'm mostly trying to find efficient methods for showing EULA (minimizing confusion for the user) and understand how users react to different approaches. Generally no one reads the EULA and my goal is not to enforce a new behavior, but I've seen different solutions that I react differently upon so I thought maybe someone more ambitious had already investigated in this.

Appreciate any help, thank you advance!
