Science does not rely on authority as an indicator of truth.

Ben Goldacre: Battling bad science


Go to transcript

It is worth reiterating that contrary to popular depictions of science, science does not rely on authority as an indicator of truth.

The video reminds me of an xkcd comic showing the problem with using statistical significance if the studies showing no effect are unreported.

Significant
In this analogy, the study showing a link between green jelly beans and acne has only a 5% probability (or less) of being a coincidence (p < 0.05). This would be convincing evidence that there is a link between green jelly beans and acne, except all the 19 studies showing no link between non-green jelly beans and acne were unreported and discarded. If all the study results were reported, then it would suggest that the result of the green-jelly-bean study is indeed a coincidence: 1/20 = 5%.

Scientific studies in real life can be even worse. Companies, and even university researchers, are not obligated to publish studies in which the results show no effect (studies with “null results”). This means that researchers can run the hypothetical green-jelly-bean study 20 times until they get the result that they want, by coincidence. What normally happens does not involve ill intent, but has the same effect. The hypothetical green-jelly-bean study is run independently by 20 different research teams (who can be separated by time), who are unaware of each other, because studies with negative results are not published. Only the group with the positive result publishes its results, but the result is actually a coincidence. See the concept of publication bias at Wikipedia.

Canadian White Person: “He might be a Canadian citizen but he’ll never be a real Canadian.”

Together, womyn of colour struggle with shadeism.

This well-done, Canadian documentary (20 minutes) on shadeism and light-skin privilege features the stories of young womyn of colour from Toronto:

Nayani Thiyagarajah narrates:

Four women, four stories, all connected to my own. We represent the Caribbean, South America, Africa, and South Asia. We represent Grenada, Venezuela, Trinidad, Angola, Bangladesh, and Sri Lanka. We represent Canada. Really, we represent an international narrative of sorts, a collective Herstory of womyn of colour. These are my friends, womyn I talk to, spend time with, and share with. And we all share the issue of shadeism from within each of our own cultures. Because of this, I knew it was important for us to come together, to talk about where shadeism comes from, how it affects us, and how we can possibly move forward together.

Chinese Canadians and First Nations peoples (not mutually exclusive)

Zuky, now a Vancouverite and tumblogger, brings us news from the West Coast:

The Chinese Canadian Historical Society of BC produced this short video explaining their project “Chinese Canadians and First Nations: 150 Years of Shared Experience”. The project was actually initiated by two UBC students of aboriginal ancestry, Amy Perreault and Karrmen Crey, who produced a short video entitled “Why Do Indians Like Chinese Food?”. When Karrmen Crey was growing up, her father used to tell her, “Do you know why Indians like Chinese food? Because Chinese restaurants were the only restaurants we were allowed in to eat.”

This is a trailer for Cedar and Bamboo, a 22-minute documentary exploring stories of people of Chinese and First Nations ancestry.

I was wondering why the older lady in the video had an accent if she was born in Vancouver, and then I realized that she grew up overseas in a Cantonese-speaking society and then returned to Vancouver when she was an adult.

(Female) Geek = Geek^2

Over at Geek Feminism, Metaneira explains why Team Unicorn of G33k & G4M3R Girls fame are doing it wrong. The “G33k & G4M3R Girls” music video, stereotypically, portrayals female geeks and gamers as sex fantasies of male geeks and gamers. Metaneira writes:

From the very start, Seth Green asks, “Hello friends… don’t you want to meet a nice girl?” The video is not aimed at the women it is purporting to celebrate: it is straight-up pandering to the largely sexist, male-centric geek subculture. It is geek women served up for the male gaze on a shiny latex platter. This is not empowering. […] It isn’t really about geek women at all — it’s just about how men would want to have a smoking hot girlfriend who can talk about Star Wars and play D&D with them.

It’s a pretty good post, and she relates the video to a general pattern in geek culture, where straight male geeks express positivity towards the idea of “geek girls”, but only so that they can get girlfriends:

And I’m tired of a subculture telling me that the only way I can belong to it is if I offer myself up as a sex object to the men involved. […] my status as a female in this male-dominated space was always underscored: my Otherness had to be reinforced at frequent intervals. I didn’t really belong.

Serendipitously, a few days later, I came across this song written and sung by Marian Call and made into a YouTube video by mercutio531. I thought it was an “answer” to the G33k & G4M3R Girls video at first, but it was actually uploaded a long time ago and written years ago.
