The popularity of a belief does not grant validity to a claim. "May" is a word that does not belong in scientific language. If there is evidence for a claim, you state it. If there evidence against it, you state it. If there is no evidence either way, you say "I don't know." "May" implies something is possible without the burden of identifying the evidence that suggests that possibility. Consider a different statement: assume there was a study that showed rhino horn is not effective in improving mental performance in young adults, and then you read "Rhino horn may still prove useful for those suffering from cancer, the researchers cautioned." How would you react?
