Why the movie ‘Don Jon’ has nothing to do with porn (also, spoiler alert)…


(… and why the image above is VERY much porn)

There are only a few things he cares about: his body, his car, his place, his church, his bros, his girls and his porn. This guy is the definition of a narcissist. He’s in his mid-20’s, still goes out to clubs, has a job as a bar-tender, no permanent relationship. He clearly doesn’t care about anyone. But, at the same time he sells the “cool bachelor” image very well. Of course, who doesn’t want to be like him: fit, popular, lots of girls. Except of course he admits that he likes porn more than sex. Porn lets his imagination do whatever it wants, real girls don’t – that’s the definition of narcissism.

But this movie isn’t about Don Jon because he admits that he has a problem. He says it, right at the beginning of the movie. Yes he has an addiction. But he realizes it. He asks for weekly forgiveness for it. What you thought adding church and porn in the same movie was a coincidence?

This movie is not about porn at all. It is about everyone else in the movie. It’s about narcissism and addiction.

Notice how the father is oblivious to the world while watching TV. Notice how the mother is insistent on Jon getting a girl and having kids. Notice how Barbara is looking for a “perfect man”.

This movie is not at all about porn. The porn is just a distracter so that the movie can sell you a whole other kind of “porn”.

It’s a movie about narcissists for narcissists because some will criticize how shallow the characters were, how shallow the plot was, how repetitive it all was. But that’s the whole point. The characters are shallow because they don’t care about anything or anyone.

Notice how the father couldn’t care about what happens to his son. There wasn’t a single time when he asks him how his job is, how his night-school course is. He just lives in his own fantasy of TV-sports [addiction]. He snaps out of it to comment on the hot girlfriend but only so that he can comment on how Don Jon “scored” on this one and how his wife used to look exactly like that.

The mother is pretty much the same way. She is focused on Don Jon having kids, so that she can have grandkids. She is focused on the image of looking like a grandmother and therefore needing HIM to produce grandchildren to support this image [addiction]. She also never cares about how his life goes. She is so focused on her fantasy that she can’t even notice how his father is macking on the hot girlfriend. She can’t even snap out of it when he finally tells them that he broke up with Barbara.

The girlfriend, Barbara, is so clearly a narcissist that I don’t think I need to explain it. Her fantasy is finding that perfect man who will live up to her every dream [addiction]. This is exactly why she will never find one. But the point is exactly NOT to find one. A narcissist can never find what she wants because she is incapable of loving any one thing. The point is to live in a fantasy – that is the addition.

There are some interesting characters placed in the movie, specifically – the sister and Don Jon’s friend. They’re not real characters. They’re just there to demonstrate a point.

The sister initially comes across as a typical, always-on-the-Smartphone [addiction], narcissistic teenager. But she drops one line in the whole movie and that line is just to make it painfully obvious, for those that still haven’t figured it out – THIS MOVIE IS NOT ABOUT PORN.

Don Jon’s friend exists just to make a contrast to a non-narcissistic character. Think about it, he is the only one that makes an effort to come and find out how Don Jon is doing. He supports him and convinces him to go back to school. He’s probably the ONLY non-narcissistic character in this whole movie. But wait, he might not be a narcissist, but your fantasy certainly is. Because your fantasy needs this (otherwise) barely involved stranger to randomly come and save Don Jon. Save him from the narcissistic injury – of course the girlfriend was a bitch for dumping him!

But what about Esther (Julianne Moore)? She’s not narcissistic at all. Hold on, she’s not even a character!

But what about her back-story? Well, for one, she’s obviously the therapist. For a random lady taking a night-class with her back-story she is surprisingly insightful. She is also stubbornly interested in solving Don Jon’s addiction to porn, pretty much the moment she catches him watching it in class. Oh yeah, she also smokes pot [addiction].

Finally there’s another addiction hidden in the plot – the idea that some life changing event is all that’s needed to make your life better. Call this the “American Dream” if you want or believing that you have a special place in the universe. All of this feeds into the plot. The church places people and Christians in a special place in the universe. The movie places the viewer in a special place. Specifically, the viewer is placed in the seat of the priest to judge Don Jon. You’re almost forced to guess how many Hail Mary’s Don Jon will have to say to atone for his “sins”.

The movie makes a special contrast between porn love and non-porn love. It builds the characters especially grey and shallow, so that you cannot sympathize with any of them. None of them have anything special to offer. But this is perfect for a narcissistic audience because then you don’t need to make a decision on who is a protagonist or antagonist – every opinion is valid, right? But surprisingly, the movie still pulls off a fairy-tale happy ending. There you go; you’ve been sold another “porn” piece.

You’ve been again sold a fantasy that any problem can be solved over-night with some magical, wise, intervention. That some external, all-knowing, insightful, source can be the solution to your problems. All you need to do is find the love of your life and your porn-addiction will go away right? All you need is a wise, usually silent little sister, who can drop the right line at the right time and solve your family problems, right? THAT is the real porn that is sold to you at the end of the movie. All the stuff at the beginning – just plot building.

Since it’s not obvious how any of this has to do with science, let me tell you why it does. This last part, the part the movie REALLY sells to the viewers is exactly why all the “integrative medicine” is proliferating. People are addicted to many things in many forms. If you think that when you use a homeopathic product you are any better than Don Jon, think again. With the advent of Dr. Google and patient-centered care, healthcare stopped feeding into people’s narcissistic addiction to magical solutions that require no effort on their part. Unfortunately “integrative medicine” is still selling this addiction. That is exactly what this movie is trying to tell you – wake up, you’re being sold an addiction. You will buy it, even if they tell you right on the label – “this is not real”.

Google “breasts” to find good science

Why can't I find that prolactin pathway in Google Images?

Why can’t I find that prolactin pathway?

Recently I was reflecting on the utility of fighting un-scientific and often outright quack medicine. ScienceBaseMedicine does a great job of explaining why all the un-scientific and unproven treatments out there don’t work. But sometimes it feels like an analogy of telling kids not to smoke or do drugs. The ones already convinced won’t do it, the ones that already do it will find reasons not to listen. The real concern is the naive audience. This third group of kids were blissfully ignorant of all the addicting stuff out there, and with some luck, they might have remained so. Yes, I hear you, there’s hardly a kid out there who is truly ignorant of cigarettes, marijuana and other drugs. But there’s a large group that simply don’t care enough to do it. In high-school senior year (grade 12) about 13% of students smoke, about 25% smoke marijuana. [Disclaimer: maybe a higher percentage try smoking/drugs throughout high-school and there is certainly under-reporting happening, but on the same note, the two groups are not mutually exclusive either].

So, say I’m Jenny McCarthy and I think vaccines are the spawn of devil. I go on air and just shout down any reason and rationality, drag my autistic child into it, make the bleeding hearts sympathize with me.

What happens then? Something like ScienceBasedMedicine can come along and try to prove that I’m wrong. Every doctor and scientist in the world can cite data and provide evidence but the Joe Smith in the crowd will just look at them blankly and say “but her child is autistic”. Done. Argument over. You lost.

Not only that, but increasing publications online bring up more keyword searches on things like homeopathy, touch therapy, energy therapy and what-have-you. In other words – any publicity is good publicity. Google doesn’t generate search results based on good vs. bad evidence. Google generates searches based on key words. (Yup, I just did it too).

So when you type “touch therapy” into Google, you get nice relaxing pictures. Most of the websites that come up promote it. And even [the skeptic dictionary] says “Therapeutic touch (TT) is a type of energy medicine whereby the therapist moves his or her hands over the patient’s “energy field,” allegedly directing the flow of chi or prana so the patient can heal.” These are the first thing that people see in the definition. What, you thought that you put “allegedly” in there and now people will become skeptical? What if you already believe in energy fields? Then you just copy and paste the first line of the definition from and there you have it, just effectively defined (and thus supported) touch therapy.

“But, that’s not all that says!”

Nope, but who cares? Scientists and doctors fighting the anti-vaccine movement also say a lot of stuff. But people only hear “autism” like it’s some kind of satanic possession to be exorcised. Bring in the exorcist [ahem, I mean, Jenny McCarthy]!

When you type in “breasts” into Google images you don’t expect to see anatomic diagrams and endocrine glands do you? Remove the filters and try it. You know what, don’t remove the filter. You still get porn. Don’t argue with me about the definition of porn – if the image isn’t there for surgeons and physicians, it’s porn.

So get this, your kid goes to school and he gets told that smoking is bad because it’ll cause cancer, so maybe your kid is smart and won’t smoke. He gets told that drugs are bad, but not very specifically, so very few kids will do crack cocaine but (and thus the above statistics) but more will smoke pot than cigarettes.

Now, go visit their science class. What’s the last time the biology or chemistry teacher made a link between medicine (applied science) and basic chemistry? So now you expect this kid to graduate and make the link himself?

“My kid is smart, he got 90% in Chemistry“. You’re missing the point. He didn’t get 90% in Applied Pharmacology did he? It’ll be another 12 years until he can get a PhD in that. But before he does, Google will make the link for him. And Google doesn’t even have a filter for “bad science”.

Now, obviously we can never get rid of all the crazies. There may still be people out there that believe that the Earth is flat, but just because they do, doesn’t mean we’re duty bound to give their voice value and send expeditions to look for the edges of the world. So if we don’t do that, why do we keep on commissioning publicly funded trials and laboratories to test completely unscientific practices in health care?

The point that I’m trying to make is that, while writing about how un-scientific medicine is wrong is important, it is also important to expand our scope to teach people, and especially children about science. And for god’s sakes, please make the links for them. Don’t leave Google to teach the rest of the chemistry lesson to your child.

P.S. I’m hoping that Google will associate “satanic”, “possessed” and “Jenny McCarthy” and the Catholic Church will exorcise her.

Bad science, bad reporting and will somebody think of the children!


We all know that smoking is bad, and marijuana smoking is bad, and alcohol is bad. And obviously obesity is bad and having a sedentary life style is bad. And eating your fruits and veggies is good. And we’re mulling the same, non-actionable information over and over. In the Globe and Mail and on CTV and on the Canadian Healthcare Network and of course the Huffington Post.

“It shows that over the four years of high school, the number of smokers went up 170 per cent, binge drinking jumped 167 per cent and marijuana use rose by 124 per cent.” … Also, they got taller [shocker]!

Is this research really adding anything to what we already know?

Here’s the ACTUAL graph from the article (something the Globe and Mail won’t show you):


1. The study does not and cannot show that the number of anything went up, or down or make any claims about the rate of change of anything. It’s a cross-sectional study for god’s sake! This graph only shows what the difference is between the different grades. It’s entirely possible that we’re doing a good job and those Grade 9 kids won’t smoke any more than they already do.

In order for them to show that the numbers “went up” they should have done a cohort study, where they followed Grade 9 students throughout highschool and found that more smoked by the end. But they didn’t do that.

2. What’s up with the relative percent reporting?

What they should have done is say 5 out of 100 Grade 9 students smoke, in comparison to 13 of 100 in Grade 12 [1]. Same goes for all the other “relative increases”.

Now, I want 0% of people to smoke obviously, because it’s bad for you. Causes respiratory diseases, cancers and all kinds of other nasty things (like impotence in males). But the question is, are we doing a good job of decreasing the number of smokers?

The Health Canada Youth Smoking Survey (incidentally done between the same years 2010-2011 as the study in question) reports 10% of Grade 10-12 students smoked (similar to this study, nothing new there) [2]. Here’s the caveat, the same survey showed that 13% of Grade 10-12 students smoked between 2008-2009 [2].

If we reported these numbers in the same “relative” percentages we could say that between ’08-09 and ’10-11 there was a 23% decrease in smokers among high school students!

So while, it’s not perfect, but we’re improving pretty quickly. In fact, if we maintain this “23%” reduction every 3 years or so, in a decade we’ll have almost no smokers.

“But Pharmer, you can’t extrapolate numbers like that!”… why not? They do it in national publications!

3. Other things are more worrisome.

Absolute numbers are VERY important here. 13/100 – 5/100 = 8/100 extra smokers in Grade 12 vs. Grade 9 [1]. BUT marijuana, while having a lower relative percent difference (123% vs. 170%) actually looks something like this in absolute terms: 26/100 – 12/100 = 14/100 [1]. Although according to Health Canada, this was a decrease from 2008-09 as well [2].

So they make tobacco look like a big problem, but we’re doing pretty good at reducing that. Why such a absolute jump for marijuana? Are students switching from tobacco to marijuana? Are we sending conflicting public health messages? How do students perceive the risks of smoking, alcohol and drugs? Can a well designed argument flip students to the dark side? [3]

4. Alcohol use.

Same thing as with smoking. Relatively speaking the percentages went up but according to Health Canada, that’s actually a decrease compared to how many were binge drinking in 2008-09 (it actually went down from 33% on average to 39% on average) [2].

Also, “binge drinking” is defined as “5 or more drinks on a single occasions in the past 5 months” [1,2]. While this is fine as an operational definition for public health (and these kids shouldn’t be drinking anything anyway, because they are under the legal age), 5 drinks is hardly “binge drinking” in terms of the real world. It’s certainly “social” drinking but few people will be trashed after 5 drinks. It’s also bizarre to me that 2 drinks/day is OK according to Health Canada, but 5 drinks on one occasion every 5 months, and you’re a binge drinker?

5. I’m not against getting students to stop smoking/drinking/using drugs. I’m against bad science and bad reporting. Both this study and Health Canada reported similar statistics and these come from the same place – the School for Public Health at the University of Waterloo, so why are they painting a different picture? Is the message “we’re doing good, but we need to continue improving”? That’s fine, but why not conduct a well designed cohort study and actually track how many students will take up smoking/binge drinking/what-have-you?

How about adjusting for bias? The Health Canada website reports extremely overlapping ranges between the different grade levels [4].

6. It’s all political

Healthcare budgets are getting thin and everyone wants a piece of the pie. Obviously it’s more dramatic to report on increasing numbers than on the successes. The way forward should never be based on misrepresenting reality, after all such data manipulation gets pharmaceuticals withdrawn from the market (case-in-point Vioxx).

Just because getting students to quit smoking is a noble goal, doesn’t mean that white lies are OK. Stop publishing incomplete and poorly interpreted data in popular news outlets!

Science Based-Evidence Ship (Replacing the EBM Pyramid)

It is enough to do a quick Google Images search for the words “evidence based medicine” and you get a whole bunch of pyramids (aside from other irrelevant stuff).

Of course, when looking at a pyramid you can get a sense that you can look at only the top 2 layers and disregard the rest. In fact, sometimes, you can even get a sense that you could simply discard the rest. Conceptually this makes sense when you look at something like a pyramid. Although the top layers build on the bottom layers, the layers appear largely independent.

In fact, the relationship is very bizarre. For example, if you place a meta-analysis at the top of a pyramid you can understand that you couldn’t have a meta-analysis without some clinical trials, such as randomized controlled trials (RCT). But a good meta analysis will usually critically appraise the studies included and strive to include only high quality RCTs. You can certainly include case-control and other cohort studies in a meta-analysis, but this mixing of studies would usually weaken it. It is also obvious that we cannot skip from basic science to a meta-analysis (because there would be no patient data to combine) [1].

Aside from this connection of clinical trials to a meta-analysis, it is quite unclear how other types of evidence in the EBM hierarchy of evidence are linked to each other. Is a case-control conducted to look for side effects of a drug linked to an RCT of the drug’s efficacy in any way? How does animal research fit in? How does basic, fundamental science, link to the top of the pyramid? Can we simply skip the “rungs” in the pyramid and hop directly from basic science to an RCT? And while the definition of EBM calls for the use of clinical experience and patient values, it is quite unclear how these interplay [2].

When you look at things like homeopathy it becomes clear, that they simply skip the basic science and jump straight into clinical trials. Sometimes they make a crude attempt at basic science but that is flawed and rarely makes the leap to construct higher levels of evidence [3,4].

There have also been proposals to utilized lower levels of evidence on the pyramid when higher levels are absent. This makes sense, but only for those treatments that have a solid scientific base. But what if there is no scientific base, what can we move down to? Once one can assure a solid scientific base, one can move on and think on a higher level of clinical trials and meta-analyses. This does not work for treatments that lack any background evidence and do not stand on a good base.

There are also proponents of the approach “if it’s stupid and it works, it’s not stupid”. In other words, if we took a homeopathic treatment and ran it through a whole bunch of clinical trials and got good results, we could then accept it as valid. Never mind the fact that we haven’t the slightest clue about how it works. The end justifies the means? I think not. The scary thing is that it’s already happening – we are chasing our own shadow. Every time the results are no better than placebo and yet every time we see a new shadow we chase it again, expecting different results.

“Insanity: doing the same thing over and over and expecting different results” [5]

Looking back at things like mathematics and physics where you are always urged to “show your solution” it becomes clear that simply guessing the answer is not a good approach. It’s not a good approach because you don’t really understand what has been done and quite possibly could not repeat the process. Since EBM stands firmly on frequentist statistics (hence the meta-analysis being the king of the pyramid) it implies that we need to be able to replicate every step in the process of evidence building. Not just repeat the experiment, but repeat every step. A treatment that was pulled out of the ether however can only be expected to work on one premise – blind luck. We could not hope to improve it or refine it. Imagine if the Wright brothers, instead of building an airplane, found an already built model. They could have then flown it and shown that it flies, but since they didn’t build it, they would have had no idea how it works. Without this knowledge of inner workings we’d still be toying around with flimsy cardboard planes.

This is where the pure EBM-ists rush in and criticize that seemingly “scientific” theories have failed in practice. They are of course right in pointing out that certain theories haven’t panned out in practice. Unfortunately they are victims to the “science god complex”. They assume that if things are based on basic science, then they must be 100% true. Perhaps there’s some misconception and disillusionment in science. Perhaps an expectation that science must always produce amazing positive results.

Unfortunately, by driving this divide between science and clinical testing, EBM opens up to pseudoscience. Both EBM and pseudoscience can say “since basic science has been shown to be false before, we should not rely on it”. But without basic science, clinical research would have nothing to direct, it would be based on blind prodding and poking with occasional success in RCTs (if you’re blindly stumbling around, blind luck can occasionally still give good results).

I would like to propose a different conceptual structure for viewing evidence in health care. This structure would have to include a base without which the entire structure collapses. The base would include all the basic science, animal research and essentially any research required to validate the reality of a drug. On top of this base we can build the levels of evidence proposed by EBM in essentially the same way as they are in the pyramid. The point is that without the base, the entire structure collapses.

Here is what I would like to propose:

SBM Structure

(Click to enlarge)

Unlike the EBM pyramid this structure makes basic and clinical sciences connected but interdependent.

1) The ship: it is the foundation consisting of physics, chemistry, biology, physiology, biochemistry, animal research, etc. Without basic science everything else drowns.

2) The sails: these are clinical sciences (roughly in the same order as the EBM pyramid puts them). Without clinical studies and clinical practice basic science on its own is immobile. It stagnates, generating knowledge without ever applying it. Without clinical science, basic science cannot be moved and directed.

Expert opinion and clinician experience can also direct science, but since they only make up part of the directing force, they would be insufficient on their own. I also placed retrospective/case-control studies on the same level as RCTs because they often study fundamentally different things. For example, RCTs are suitable for efficacy studies and can never be employed for safety studies.

This then is the interdependency of basic science and clinical science. It is not that either one is subservient to the other. Notice also the “good quality” prefix assigned to all the clinical studies. That is because “low quality” clinical studies can be rejected based on the internal validity flaws. Low quality studies do not contribute anything. They are like ripped sails, the only thing that can be concluded from them is that they should be replaced (i.e. conducted with a higher quality).
