The same effect is noticed with GMO foods. They&#x27;re better in all regards, yet there are people who are afraid of them because &quot;not natural&quot;.<p>I don&#x27;t think this has to do with the education system. My friend&#x27;s father has a terminal illness, and in his attempt to understand and rationalize it, he thought that he did it to himself by leading an &quot;unnatural&quot; lifestyle. The man has a masters in mathematics and owned a software company, he&#x27;s quite intelligent.<p>I think people just try to rationalize their situation, sometimes they rest on the idea that natural is better.
