Some love him.  Some hate him.  It doesn’t change the fact that he was still “ridiculously good looking”.

Zoolander was one of those cult movies that polarised people into “absolutely love it” or “absolutely loathe it” camps.  I admit, I’m one of the former.  (“Moisture is the essence of wetness, and wetness is the essence of beauty”  … It still cracks me up!)

For those who aren’t familiar with the story, Derek Zoolander was a top male model who was famous for his different looks: “Blue Steel”, “Ferrari”, “Le Tigre” and the famous “Magnum”. They were all the same pose, of course, but everyone thought they were different. Except for evil fashion designer, Mugatu, who in a burst of rage at the climax of the movie, yells, “Who cares about Derek Zoolander anyway? The man has only one look … Blue Steel? Ferrari? Le Tigra? They’re the same face! Doesn’t anybody notice this? I feel like I’m taking crazy pills!”

There are times when I read Dr Leaf’s social media posts, and I feel the same as Mugatu.

“Dr Leaf isn’t a scientific expert … ‘When we think, we learn because we are changing our genes and creating new ones’ … That’s not scientifically possible! Doesn’t anybody notice this? I feel like I’m taking crazy pills!”

Dr Caroline Leaf is a communication pathologist and a self-titled cognitive neuroscientist.  If Dr Leaf was a legitimate scientist, she would know that our genes do not change when we process new information. Our genes are stable. They do not change unless there’s a mutation, which occurs in one out of every 30 million or so genes. We do not make new genes at will. Last year, scientists at MIT were reported to have shown that DNA breaks when new things are learnt, but in a normal nerve cell, these breaks are quickly repaired. That’s certainly interesting, but that’s not changing the DNA or making new genes. Making claims that we make new genes to hold new information is like saying that pigs fly.

Dr Leaf’s supporters would likely make a counter-argument that she probably didn’t mean that genes really change, or we make new genes, she’s just not worded her meme properly. Well, there are two responses to that, neither of which are any better for Dr Leaf. Because scientists who really are experts don’t make errors so large that you can spelunk through them. And, this isn’t the first time that Dr Leaf has made claims about how our genes fluctuate. She made a similar claim back in September 2014. Saying the same thing several times isn’t a mistake, it shows she really believes that we change our DNA code by the power of our thoughts.

Whether someone thinks DNA is changeable isn’t likely to cause any great harm to that person, but what is concerning is that Dr Leaf has been given her own show on the Christian cable TV network TBN to discuss mental health. She’s already proven that her knowledge of psychiatric medications is dangerously flawed. If Dr Leaf doesn’t know the basics of DNA, then giving her a platform to preach something that can effect whether a person might live or die is particularly perilous.

Dr Leaf’s rise is also a worrying symptom of a Christian church that is intellectually imploding. In a 2013 blog for the Huffington Post, Charles Reid wrote,

“Christians must provide effective witness against both extremes. But before Christianity can engage atheism it must first address the scientific illiteracy in its own house. For the greatest danger Christianity confronts at the present moment is not incipient persecution, but increasing marginalization and irrelevance. If Christians cannot engage reasonably and responsibly with science, there will be no place for them in the public life of advanced societies.”

Reid was paying particular attention to Ken Ham in this blog, but the principle remains the same. Scientifically illiterate Christians quickly lose credibility with people. We can’t meaningfully engage with a person who has a rudimentary understanding of biology by proudly tell them that we create new genes with the power of thought. That makes us sound like a male model.

For the sake of other Christians health and well-being, and for the sake of our credibility and our witness, we need to critically assess Dr Leaf’s work, not promote it as another gospel.
