In Dan Ariely's book, "predictably irrational", there's a chapter about how everyone cheats a little.
And based on everyone I've met, and on Dan Ariely's own actions (1), I've concluded this one is true.
We all cheat a little from time to time.
Ex : for me, driving a few km/h above the speed limit is "cheating a little"

The ironic part is the recent fabrication controversy with Ariely. He’s recently had to retract fraudulent papers (one of them, most ironically, on the topic of honesty) because of falsified data. It makes one question the validity of all of his work.
His relationship with Jeffrey Epstein isn’t a good look either.
