The research team is hoping that the study leads to legal documents becoming more straightforward and accessible. Lawyers themselves don’t like legalese, and the rest of us have even less chance of making sense of it.

“Lawyers also find legalese to be unwieldy and complicated,” says Gibson.

“Lawyers don’t like it, laypeople don’t like it, so the point of this current paper was to try and figure out why they write documents this way.”

The research has been published in PNAS.
