""Many religions and societies link to some degree the cumulative amount of religious effort to benefits in the afterlife," said Elissaios Papyrakis, an economist at the University of East Anglia and one of the study's authors."
I wouldn't believe anything religious which came out of the UK today anyway - Now that the UK is the United Kingdom of Sodom and Gomorah.
But "religious effort = benefits in the afterlife" - Liberalism, Roman Catholicism and JW'ism etc all peddle works based religion or salvation by works as its known as. So this is probably where they get their daft ideas from, for this daft conclusion.
