0 Some quick answers to common statements about homeopathy

  • January 26, 2015
  • by Crommunist

An article published in the Guardian is making the rounds quite rapidly among my social media circles. The article, coverage of a report by the Australian National Health and Medical Research Council, makes some pretty bold statements about the efficacy of homeopathy – namely that it doesn’t work:

But the NHMRC review, conducted by a working committee of medical experts, said it had no impact on a range of conditions and illnesses including asthma, arthritis, sleep disturbances, cold and flu, chronic fatigue syndrome, eczema, cholera, burns, malaria and heroin addiction. For the 68 conditions – including those listed – the review either concluded definitively that homeopathy was not more effective than a placebo, or at the very least there was no reliable evidence to suggest it was.

The skeptics in my Facebook and Twitter feeds are, perhaps unsurprisingly, feeling pretty vindicated by this report. They (we) have been saying for quite some time that homeopathy is nothing more than a hoax perpetrated against a credible public by people who are either so craven as to intentionally exploit people’s ignorance, or so irresponsible as to refuse to examine the abundant scientific evidence that homeopathy is simply a placebo with an elaborate ritual preceeding it. I myself have participated in a couple of demonstrations of the fact that homeopathy simply does not work, both times taking an “overdose” of homeopathic “sleeping pills” that are, in fact, nothing more than sugar pills.

However, if you are not close friends with someone in the skeptics community, or if you simply don’t care to follow this particular debate, you might find yourself a bit lost. I thought I would provide my somewhat-informed take on this report and what lessons we should take away from it. … Continue Reading

4 Being less wrong about being “biased” and “privileged”

  • March 17, 2014
  • by Crommunist
  • · blog · critical thinking · privilege · science

In the course of my scientific training, I spent a lot of time receiving instruction about bias. Bias is, simply, something that influences the relationship between the elements of interest, but isn’t due to a “real” association between those elements. We’ve discussed the concept of “confounding” on this blog before. Confounding is a type of bias, wherein the relationship between X and Y is actually explained (at least in part) by the presence of a third variable, Z. The facile example is the apparent relationship between ice cream sales and drownings, when what is actually happening is that both of those things are associated with warmer temperatures rather than each other.

Bias, as a scientific phenomenon, is a serious issue. Scientists put in a lot of time and effort to eliminate bias to get an estimate of the ‘true’ relationship between different things. Some types of bias, like confounding, can be eliminated through the use of statistical methods. Other types of bias, like selection bias, can only be removed through proper study design. Other forms of bias, like publication bias (which is a serious issue for meta-analysis), cannot be controlled for at all.

Scientific inquiry requires us to consider not only the type of bias that might exist in any given study, but also the direction and magnitude of that bias. We often cannot get a precise measure of bias, but we are required to consider the ways in which our work may have been affected by structural or other biases. The best among us will discuss the way in which we could control for such biases in subsequent work, and perhaps even provide explanations of what a removal of bias might look like. This is pretty standard fodder for the ‘Discussion’ section of peer-reviewed manuscripts. It shows that we are actively thinking about and critiquing our own work, and presenting the best form of our argument that acknowledges the limitation of our data and design. Acknowledging bias is, for the most part, an indication of how strongly you should ‘believe’ the findings. … Continue Reading

11 Memories, Emotions, and Brains

One of the things I noticed when taking my Philosophy undergrad was how 17th century Philosophers (and Philosophers of other periods too) often made grandiose claims about how people thought about the world. Often their 100% certain proclamations were refuted by other Philosophers who were also 100% certain about how the world worked. A particular example of this would be the general commitment to the Platonic notion of how we are born with a complete set of concepts (believed and accepted by most philosophers prior to Locke), and then the commitment to the complete opposite, the ‘blank slate’ (Locke’s tabula rasa), the idea that we are born with zero ideas. Turns out that biology is more complex than that. Philosophy of Mind makes slow progress.

15 Pride goeth before…

  • April 11, 2013

  • · anti-racism · blog · freethought community · psychology · race · racism · science · skepticism · sociology

It has become a sort of pop-psychology truism that people who engage in prejudicial behaviour are doing so from a place of insecurity. It makes intuitive sense that if you don’t feel good about yourself, you can bring yourself up by tearing others down. Indeed, there is some evidence that threats to self-concept are likely to result in a preference bias toward the majority group (even among minority group members).

In a study by Ashton-James and Tracy, the authors propose a new hypothesis. They refer to the psychological literature that suggests that pride has two basic forms: hubristic and authentic. Hubristic pride refers to the kind of pride that is directed at one’s innate self-worth and deservedness – a kind of self-congratulatory, self-centred pride that is associated with narcissism and defensive self-esteem. Authentic pride, on the other hand, refers to pride taken in one’s accomplishments based on hard work rather than, for lack of a better term, special snowflakeness – it is associated with secure self-esteem.

The authors posit that hubristic pride will lead to increased prejudicial attitudes and behaviours, whereas authentic pride will lead to more compassionate attitudes and behaviours. They arrive at this hypothesis based on literature that suggests a relationship between self-esteem insecurity and prejudice. They go on to suggest that empathic concern is the mechanism by which this relationship manifests itself, since people who are more secure in their self-esteem are more likely to be able to be outwardly focussed and respond to the needs of others.

In order to test this hypothesis, the authors conducted three experiments, as well as a pilot study. … Continue Reading

12 Movie Friday: Empathy Boosters

This week we were treated to a bizarre bit of performance art by a commenter who decided to make no fewer than two threads completely about him and his “wisdom” about why victim blaming is okay (but when he does it, it’s not victim blaming). Y’all were way more patient with him than I would have been, but eventually I stepped in and moved him to moderation (GASP! Free speech! FTBullies! Feminazis!) because there seemed to be no bottom to his cluelessness.

Fun times.

Anyway, keeping with the theme of “Required Reading”, today’s video is perhaps best termed “Required Watching”:

7 Academic Blogging

For those of you who have never visited the excellent sociological blog Family Inequality, I suggest that you stop reading right now, and head on over there for an hour or two. Don’t worry about me, I’ll wait.

Welcome back! I hope you enjoyed your stay there, I know that I spend quite a bit of time there  (often time I don’t have) digging through the blog’s many, many entries. A while back, the blog’s author, Phillip Cohen, wrote a piece called “Should every sociologist blog?” that I shamelessly linked to my own blog. The thesis of the article was simple, is it in the interests of both sociologists and the public to encourage sociologists to blog about their research? Since I’m already doing that (in my own, rather less articulate way), I of course answered in the affirmative. For Cohen’s part there seems to be a bit more reservation about the whole idea, but I’ll leave it to him to make his own points. He’s better at it than I am.

Cohen’s question got me to thinking though: should blogging at the academic level – in all disciplines – be encouraged as a side-project for scholars? As it stands, blogging means precisely nothing on any academic’s CV, and there is therefore no real incentive for any academic to engage in it, outside of maybe their own passion for writing. But aside from filling a line on a CV, could academic blogging serve a purpose?

Hell yes, and here’s why.

Traditionally, academia has had the (fairly exaggerated) reputation as being the guardian of knowledge; a society’s culture, traditions, and memory are gathered, catalogued, and maintained by armies of scholars and researchers; scientists of all stripes, historians, anthropologists, literary theorists, etc. Of course the reputation is bullshit and much of a civilization’s knowledge is contained in the minds of non-academics everywhere; but while academics might not be the sole holders of knowledge, we do certainly hold a lot of it. It’s our job, and many of us are quite good at it.

Part of the disconnect between academia and the broader population rests in the severing of academic knowledge from other, more ‘everyday’ forms of knowing. How often do we hear the expression “oh sure they’re book-smart, but they’re not really street-smart”, or hear academia being described as an ‘ivory tower’, far removed from the affairs of the proles, toiling away far below? But the distinction between these two forms of knowing is largely artificial and it’s largely maintained by the often arcane semiotics of the various dialects of different academic disciplines. We love to make up new words and hurl them at each other, and each time we do – and each time we fail to explain to everyone else what those words mean – we further distance ourselves from our fellow citizens. Some academics, like the infamous Jacques Derrida, almost seemed to revel in their obtuseness, as though being cryptic was synonymous with being profound. And while the navel-gazing and word-play continued, many of our neighbours and friends began to lose interest in what we were talking about in the first place. Our debates take place in closed conferences and behind the paywalls of peer-reviewed journals, and our discoveries and carefully crafted ideas only ever interface with the public as short sound-bites – and only after they’ve been distorted and abridged by others. In short, academics are often dreadfully isolated from society, and it’s our own fault.

Blogging allows us to begin to change that. Blogs are a handy medium for allowing researchers and scholars to speak to the public in their own way, with their own idiosyncrasies, without having to go through someone else. Blogs allow the public to ask us questions or to challenge us directly, and they can be hopeful that we will respond (well, at least some of us). In other words, blogging can help to facilitate the return of academics into the mainstream of public discourse. Granted people like Neil deGrasse Tyson are already doing this, but he and people like him represent only the tiniest fraction of academics who ever take their research and love of educating public. Other venues, like TED talks can also help to make current research available to others, but they’re not the only way.

I’m not photogenic enough for television, and I don’t know that anyone would want to listen to me talk at them for any length of time, but I’m handy with a keyboard, and I can usually convey the substance of my own research to a broad audience fairly easily. As an academic, I feel that I have a moral obligation to take the knowledge and training I’ve received at public institutions and share it with my fellow citizens. Blogging helps me to do that.

So will blogging or some other form of (usually) non-paying, non-peer reviewed public academics be embraced by researchers any time soon? Well, probably not; as universities become increasingly corporatized and professor’s salaries and advancement are increasingly tied to their ability to churn out papers and books, the demands on individual academics’ time grow as well. Many universities now demand that the lion’s share of a professor’s day be dedicated to research and publication; a minority of time is devoted to the actual practice of educating. At the graduate level, fewer universities are even offering their students courses on how to be a good teacher. Instead, graduate students – MA and PhD alike – are indoctrinated into the world of ‘Publish or Perish‘, and if they happen to pick up some skill at teaching while they’re at it, well that’s just a happy bonus. Many current professors learned to teach only by emulating a past favourite professor and few will ever take a formal class about teaching pedagogy. At some universities, a professor’s teaching ability isn’t even a factor when determining tenure, promotion, or salary adjustment. Think about that for a second: your professors – if you’ve attended university – may likely have received zero attention or accolades for their teaching ability, because to the university, teaching ability is not important. It is a grim picture, if you are of the opinion that university professors ought to be responsible for educating their fellow citizens.

And so I’ll continue to blog. These days it seems that it’s the only way I can meet what I see as my obligation to educate.

1 Bravo to Canadian skeptics: Jenny is Dropped

About a week ago, I read that Jenny McCarthy, the celebrity face of the anti-vaccine movement, was going to be headlining an event called “Bust a Move” at the Ottawa Cancer centre. I was horrified, and spelled out my objections in a letter to their CEO:

Hello Ms. Eagan,

I am writing this letter to you to express my shock, disappointment, and outrage at Ottawa Cancer’s decision to host noted anti-vaccination activist and celebrity provocateur Jenny McCarthy as the face of its “Bust a Move” campaign. Ms. McCarthy’s actions over the past decade have revealed her to be deeply antipathetic to the process and institution of science – a process and institution that cancer patients and practitioners rely on for their lives and livelihoods. By inviting Ms. McCarthy, Ottawa Cancer is signaling that it either does not care about Ms. McCarthy’s anti-scientific views, or that it shares them.

One of the largest barriers cancer researchers face is the unjustified suspicion of not only cancer survivors but the general public in accepting the scientific facts about the disease. I am overjoyed that people are not simply adopting the asserted axioms of the scientific establishment without doing some research, but what Ms. McCarthy has been doing is something else entirely. She has, using her pulpit as a celebrity, been deliberately spreading misinformation to people who are vulnerable to the predations of opportunistic hucksters. Is it Ottawa Cancer’s position that this kind of fraud-by-proxy is acceptable simply because she has name recognition?

I strongly suggest you do not allow the reputation of Ottawa Cancer suffer as the result of what I can only assume to be poor staff work. Beyond the simple fact of public perception, you have a duty to ensure that patients are receiving a message that is grounded in evidence and best practices, not the pseudoscientific hunch-based beliefs of a woman who has been actively campaigning for years to undermine children’s public health programs. You should immediately announce that you have personally looked into Ms. McCarthy’s background and have made the executive decision not to associate the good name of Ottawa Cancer with her anti-science advocacy.

Do the thing that is not only right for your organization, but for the cancer survivors and families who rely on Ottawa Cancer for sound information and advice.

Skeptics across the country, buoyed by editorial pieces in MacLean’s and the Ottawa Citizen, lobbied Ottawa Cancer to drop Ms. McCarthy from the event (coining the hashtag #dropjenny).

And it worked: … Continue Reading

3 A truffle rooted out from the heap of… bad news

  • · blog · Canada · crapitalism · economics · gender · good news

There was one more bit from one of this morning’s stories that I thought was an interesting development, and deserved its own post:

The proportion of women among the ranks of Canada’s wealthy elite has almost doubled over the past 30 years, new data released by Statistics Canada Monday shows. The data agency published its analysis of the richest one per cent of Canadian tax filers between the years 1982 and 2010 on Monday. From the total number of all Canadian tax filers, Statistics Canada narrowed its list down to 254,700 people at the top, who make up Canada’s “one per cent.”

Among numerous findings, the proportion of women in that group nearly doubled over the time period, from 11 per cent in 1982, to 21 per cent by 2010. That’s 53,200 individuals. The women in that group were slightly less likely to be married or partnered than the men were. Some 68 per cent of women were married or in a common law relationship, compared with 87 per cent of men.

So the sort of ‘broad brush’ good news aspect is that there’s something in the Canadian economy that makes the elite-level wealth professions not quite as gendered, or at least less gendered than it was in 1982. Whatever structural adjustments that have been at the levels of education and training, and more than likely an accompanying cultural shift in attitudes toward women, has resulted in the closure of a gender gap in this particular echelon. This news fits well with shifts we’re seeing in political representation at the highest levels of government. So while we’re not seeing proportional gender representation in all walks of life, we’re at least seeing things moving in that direction.

Awesome. … Continue Reading

30 Another stake in the heart of colour blindness

  • January 30, 2013

  • · anti-racism · blog · psychology · race · science · skepticism

I hate “colour blindness” as a racial philosophy. Well-intentioned though it may be, it’s a profoundly unhelpful and unworkable proposed solution to a very serious intercultural issue. Is there any other problem on the planet that we think is best addressed by simply pretending as though it isn’t there*? For every other social issue I can think of, failing to at least appreciate the existence of reality is seen as a vice, not a virtue. And yet, when it comes to race, we have somehow managed to convince ourselves that the ostrich has the right idea.

Liberals and conservatives alike have expressed serious resistance to the idea that ignoring race doesn’t solve race. As I’ve explained before on this blog, a couple of times actually, colour blindness not only doesn’t bring us any closer to solving racial issues, it actually makes us less able to describe and address those issues. Far from being a solution, it makes us silent on the problem, meaning that the unacceptable status quo of racial inequalities is allowed to run its course unopposed.

So once again, it’s skeptics to the rescue, this time with a study examining a novel downside of the “colour blind” approach. Researchers at Tufts and MIT examined the effect of “colour blind” approaches to problem-solving in an experimental setting. … Continue Reading

The following post is a continuation of a discussion we began this morning, looking at a paper by Daniel Effron and colleagues. In it, the authors conduct a number of experiments to investigate a phenomenon in which white people demonstrate a tendency to use salient examples of being “not racist” (choosing not to accuse an innocent black people in favour of a more guilty-seeming white person of a crime) to license more racist behaviours in the future.

The fourth investigation the authors conducted invited people to try and remember the number of racist decisions they didn’t make, after presenting them with statements that were either clearly racist, ambiguously racist, or racially ambiguous (i.e., no racial content). The authors hypothesized that, given a clear-cut and obvious example of a time when they were “not racist”, the drive to appear “not racist” would be satisfied, thus obviating the need to introduce “not racist” narratives into their memory. In other words, if you have a ready memory of choosing not to be overtly racist, you will have less motivation to seem “not racist” in a subsequent decision. … Continue Reading
