Only fans of defending champions Australia had less faith in their players' sporting ethics, a fallout of the 2018 ball-tampering scandal that led to skipper Steve Smith and his deputy David Warner being hit with 12-month bans from the game.
"It looks like England have traded in their reputation for being nice for being winners. Many fans will settle for that if it means lifting the World Cup this year," YouGov Sport commercial director Charlie Dundas said.
The data also showed that the English public was the least likely to believe cricket was a game played with a high standard of sporting ethics.
"There is an alternative explanation (for the data)," Dundas said. "The lower a country sets the bar on ethical expectations, the more likely it is that a team will meet them. It could just be that the English public sets the bar higher."
England began their World Cup campaign against South Africa at The Oval on Thursday.
