Answering Cancer Quackery: The Sophisticated Approach to True Believers

 You can lead a true believer to facts, but can you make him think?

You can lead a true believer to facts, but can you make him think?

I got an e-mail with a link to a video featuring “Dr.” Leonard Coldwell, a naturopath who has been characterized on RationalWiki as a scammer and all-round mountebank. Here are just a few examples of his claims in that video:

  • Every cancer can be cured in 2-16 weeks.
  • The second you are alkaline, the cancer already stops. A pH of 7.36 is ideal; 7.5 is best during the healing phase. [We are all alkaline. Normal pH is 7.35-7.45.]
  • IV vitamin C makes tumors disappear in a couple of days.
  • Very often table salt is 1/3 glass, 1/3 sand, and 1/3 salt. The glass and sand scratch the lining of the arteries, they bleed, and cholesterol is deposited there to stop the bleeding.
  • Patients in burn units get 20-25 hard-boiled eggs a day because only cholesterol can rebuild healthy cells; 87% of a cell is built on cholesterol.
  • Medical doctors have the shortest lifespan: 56. [Actually they live longer than average.]

My correspondent recognized that this video was dangerous charlatanism that could lead to harm for vulnerable patients. He called it a “train wreck, with fantasy piled upon idiocy.” His question was about the best way to convince someone that it was insane. He said, “If you could rely on someone to follow and understand basic information about the relevant claims, it would be a gimme. But to the casual disinterested observer, who can interpret the whole video as ‘Well, he just wants people to eat right,’ pointing out the individual bits of lunacy just looks like so much negativity.”

He asked, “How do I best represent what’s happening to someone who is either a) emotionally invested in this and/or b) casually approving of it? … I just want to be patient, not shout anyone down, not make anyone defensive, and then win. Very surprised I don’t already know how. But I feel like I don’t. What is the psychologically sophisticated approach to this?” (more…)

How to Build a Bridge

People tend to limit their reading to sources that agree with their beliefs. We find ourselves mostly preaching to the choir; our message usually doesn’t reach those who most need to hear it. I recently received an inquiry from a science-based medical doctor asking how to approach others in building a bridge to clarify so much misinformation.

My first thought was that you can build a bridge but the real challenge is persuading people to cross that bridge. Like leading a horse to water…

How to approach others? That’s a tough question. The best approach varies with the individual and with where he is in his journey. Confrontation seldom works: it just makes people angry. It is counterproductive: it only serves to make them invent more rationalizations to defend their beliefs. Although sometimes anger can be a good thing. I got an e-mail from an acupuncturist who was incensed by an article I wrote saying that acupuncture was not based on good evidence. He set out to prove me wrong by looking up the evidence behind what he had been taught by his teachers about acupuncture’s efficacy for specific conditions, and when he couldn’t find any, he realized that his teachers and his textbooks had misled him with lies. He gave up acupuncture and went back to school to learn a science-based health profession. (more…)
