I want to say the following sentence in a succinct way:
"The study conducted in [1] reveals (a new insight into) the role of X, which is contrary to what people thought the role of X was."
For example, I want to convert to something like this:
"The study conducted in [1] reveals a -[completely different from what people thought]- insight about the role of X"
The word controversial does not really work here because the study proves that the role of X is actually Y, not Z (which people used to think). Also, to avoid technical Jargon, I want to avoid saying Y and Z. I appreciate any suggestions!
