A study of English proverbs created since 1900 showed in the 1960s a sudden and significant increase in proverbs that reflected more casual attitudes toward sex. Since the 1960s was also the decade of the Sexual revolution, this shows a strong statistical link between the changed values of the decades and a change in the proverbs coined and used. Another study mining the same volume counted Anglo-American proverbs about religion to show that proverbs indicate attitudes toward religion are going downhill.
