Back in May, Uri Simonsohn posted an article to his blog about studying effect sizes in the lab, with the general conclusion that the sample sizes needed for a precise enough estimate of effect size make it essentially not feasible for the majority of lab studies. Although I was not at the recent SESP conference, I have been told he discussed this (and more!) there. Felix Schönbrodt further discussed Simonsohn’s point, noting that reporting the effect size estimates and confidence intervals is still important even if they are wildly imprecise, because they can still be used in a meta-analysis to achieve more precision. I think both of these posts are insightful, and recommend that you read them both. However, both of them use particular examples with a given level of precision or sample size to illustrate their points. I wanted to go a bit more in-depth on how the precision level and effect size changes the sample size needed, using a tool in R that Schönbrodt pointed out.Continue Reading
I’ve been watching the recent debate about replication with interest, concern, and not just a little amusement. It seems everyone has their opinion on the matter (leave it to a field of scientists to have twice as many opinions as there are scientists in the field!), and at times the discussion has been quite heated. But as a grad student, it’s been difficult to know whether I should throw my own hat in the ring. With psychology heavyweights like Kahneman and Gilbert voicing their opinions, what room is there for a third-year grad student? But fortunately (or unfortunately), I’ve never been one to know when to keep my opinions to myself, so I want to present my own thoughts on the matter. My perspective is that, even if the issue gets heated at times, this discussion can be fruitful as we learn to navigate a changing discipline.Continue Reading
One of life’s great ironies in the Western world is the number of people who fervently declare the great success and capability of capitalist enterprise, and then turn around to lament the gross inefficiencies of government. The staunchly conservative among us love to trumpet this apparent contrast. Then again, the liberals among us have their similar contrast, decrying the ruthlessness and greed of business, and pointing to the sober diligence of government regulatory agencies. Both sides love to contrast the business world with the government system, for each their own purposes.
In fact, the irony of this is that these two systems are two sides of the same coin. Governments are plagued by inefficiency precisely because they are run in ways that resemble capitalist enterprise. Sure, in government the currency is different—politicians earn seats in government, and they sell influence—but they run as a business all the same. Let me paint the picture in more vivid colour.Continue Reading
Folks, when you’re travelling, make sure you know where your passport is at all times. Why do I say that? Because forgetting your passport at an inopportune time can lead to the biggest headache that you’ll ever face. I now know this from personal experience. Gather ’round, kids, and let me tell you the story of when I made a stupid mistake and then suffered for it for the rest of the day.
The story begins in Chicago. Yesterday. My friends and I had arrived at O’Hare airport on our way back from a social psychology convention in Austin. We had a layover in Chicago and were waiting for our second flight to the Kitchener airport. It was an evening flight, and I was looking forward to being home. The employees at the desk announced that our flight was ready to board, and I grabbed my things, ready to finally leave! And then they announced, “Because this is an international flight, please have your passport ready to show the attendant along with your boarding pass.” And that’s when my heart sank.Continue Reading
About a month ago, Switzerland made international news by holding a referendum on whether or not to give all Swiss citizens a basic income of about $2800 a month. Although the date for the vote still hasn’t been set (as far as I can tell), it certainly raised quite a buzz as analysts tried to frame the pros and cons of a proposal that, quite frankly, is not a new idea at all. Here’s a good summary of some of the arguments and research on the issue.
At its heart, a “basic income” proposal is a system in which each resident of a particular country or region receives a sum of money unconditionally by the government. Unlike many systems of welfare, such money comes with no strings attached, and no means testing to ensure that one needs such assistance. This means that it cuts out much of the bureaucracy involved with welfare benefits: no more case workers ensuring that people are indeed looking for work; no more food stamps that force individuals to spend money on food rather than on other items that may be equally necessary. The system, at least in one sense, is inherently fair, in that everyone in the country receives the same amount: rich or poor, every person gets the basic income from the government.Continue Reading
I’ve been a vegetarian for about a year and a half now, and reduced my meat intake for a couple years before that. This wasn’t a complicated or difficult process, despite what some people seem to think. The most difficult part of being a vegetarian (at least for me) is dealing with situations that arise when one is with friends and family who aren’t also veg*n. Since I’m fresh off the holidays and have spent the past six days with family, none of whom are veg*n, I wanted to share just a few situations that can be tricky to deal with. But first, a few definitions, just so we’re clear:
Vegetarian: A person who does not eat meat. Vegan: A person who does not eat or otherwise use any animal products (e.g., dairy milk, eggs, honey, leather, cosmetic products tested on animals). Veg*n: A catch-all term used to refer to people who are either vegetarian or vegan, or something similar. The Questions
As I said, none of my family is veg*n. I am alright with this; I view moral issues (especially ones concerning diet) as personal choices that must be made by an individual. I am not here to judge, just to follow my own personal standard of ethics. But that can make for some situations that get tricky or somewhat frustrating. For instance, almost invariably, the first question a veg*n gets asked when they mention that they are veg*n is some variant of this: “What do…Continue Reading
I’m exhausted. The past few weeks I’ve wanted to do nothing except curl up in a ball under a blanket and shut out the world. It’s not depression, and it’s not cynicism; it’s just apathy resulting from utter exhaustion at trying to keep up with all the social movements that I consider myself a part of. In my head, I find certain ideological standpoints to be important: feminism, animal rights, environmentalism, leftist politics, skepticism, and so on. But lately, I find myself just not being able to care about taking any action toward these ends. My resources are completely depleted.
Of course, some of this is due to external demands that have left me depleted. I just finished writing my MA thesis, so that’s taken enormous time, effort, and brain-power. I also have other demands on my time, as we all do. But I think the problem runs deeper. I am simply burnt out from moral outrage.Continue Reading
