I don't need "data" to show that when someone does X which isn't part of their job in preference to fixing longstanding problem Y which they're directly responsible for, they must prefer working on X to Y. We all have blind spots and areas where we prefer to focus that might not align with what's most important. This is something you can see at every level and my comment is based on experiences in my own career.
