John concludes that he should stop drinking fluoridated water to ensure that he doesn’t develop bone cancer because the majority of the male test rats that drank fluoridated water developed bone cancer.
John reasons that because male test rats developed bone cancer from drinking fluoridated water, he should stop drinking fluoridated water, as stopping will ensure that he doesn’t develop bone cancer. However, John fails to consider the possibility that male rats react to fluoridated water differently than humans or that he could still develop bone cancer even if he stops drinking fluoridated water.
