Lately I’ve been reflecting on failure. It’s interesting to see how it’s handled quite differently in sport than in academics. I suspect that’s because failure in sport is manifest and public, while failure in academics is obscure and private. These features encourage camaraderie and other healthy coping strategies in sport. As to how to transfer these lessons into academics, I’m not sure, but it’s an interesting case study nonetheless.
Descartes famously claimed that “there are no definitive signs by which to distinguish being awake from being asleep” (Cress’s translation, Meditations on First Philosophy). There are a few possible interpretations of this claim, but an influential one is phenomenological. Dreams, and hallucinations of other sorts as well, do (or at least can) reproduce what it’s … Read more
Recently I published a paper on hallucination. Since the paper is long and technical in ways that obscure what I take to be its key insights, I wanted to write up those insights in a more accessible (and succinct) form. Often, when we have normal perceptual experiences, it appears to us that our experience is … Read more
Most of us have many conversations each day: a quick “good morning” to our cohabitants, small talk at the office water cooler, a phone call to your mother to catch up, chatting with your children about their day over dinner, haggling with a client over price, a tax meeting with your accountant, some flirtatious banter … Read more
Why are people naturally inclined to be thoroughly convinced by confirming anecdotes, while also being naturally inclined to ignore falsifying ones? … I want to propose that we can explain this epistemically vicious reception of anecdotes by appealing to two phenomenal features of information channels.
A few days ago Mike Florio questioned, on the PFT website and podcast, the ethics of the NFL’s upcoming coronavirus testing. He asks: will the NFL’s testing requirements drain testing resources that otherwise could or would be utilized by members of the general public in a given city? Each of the NFL’s 32 teams will … Read more
People share memes all the time, even when those memes have tell-tale signs that they are inaccurate, incomplete, or in some way are trying to mislead. Similarly, people fall for advance-fee and password reset email scams all the time, despite these emails being formulaic and easy to spot. Why? I suggest here that it’s in part because of the way in which representations are transparent to us. We normally notice the message, not the medium, including tell-tale signs of falsity in the medium. I also suggest that transparency is part of why people often struggle to distinguish representation from reality.
I’ve long been fascinated by the idea that what we say using language is actually without meaning. For example, if I say “atoms of aluminum have 13 protons”, I seem to be using words to express, or describe, that atoms of aluminum have 13 protons. The quoted stuff—the words I speak—is a representation, representing some … Read more
To summarize, a preliminary analysis of the data suggests that in my first four weeks going vegan, I needed to consume somewhere around 300 kcals a day worth of food more than I was before to meet the same energy demands. That’s a shocking increase, over 11%. Whether it holds up long-term, or whether my body adapts in some way, is yet to be seen. I used to be a big believer that weight management was just a matter of balancing calories in vs calories out, but this is a pretty dramatic demonstration that since not all “calories in” are absorbed, just balancing this equation isn’t right. I like being wrong, and admitting as much.
My first two published papers were on demonstrative thought. At first glance, these papers are esoteric. The first argued that phenomenal consciousness guides voluntary attention in selecting targets of demonstrative thought. The second argued that an epistemically robust information link to a potential target is not necessary to select that target for demonstrative thought. That’s a lot of jargon. It may seem as if this is stuff only specialists could care about — and may be hard to see why they care.
A month or two back it hit me that I haven’t been bored in years. As a child in the 90s boredom was a constant threat: nothing good on TV, no neighbourhood friends around to play, etc. VHS tapes, N64, and dial-up internet could only alleviate boredom to a certain extent. I could only watch the same dozen tapes so many times, Nintendo games get old, and the internet wasn’t the bottomless content well it is today — and, it was slow.
New riders at the velodrome, watching film, are often surprised at how high they sit on the bike. They feel as if their head is more tucked towards their handlebars than it actually is. Similarly, those who ride based on perceived effort can be in for a shock once they get a powermeter. What feels to them like a nine-out-of-ten might only be 70% of their VO2max power.
Some people are normally only ever very confident about what’s true and false. Others find it hard to make up their minds. Both are bad, and lead to interesting (but epistemically vicious) dynamics in how these people form and assign credences.
Is physical endurance mind over body? I tackle this question through the lens of a new study which suggests not. I offer two thoughts on why it’s not surprising researchers in a recent high-quality study were unable to enhance endurance by enhancing the brain area involved in resisting our urge to stop in response to stress. The takeaway? Your ability to will yourself to better performance or push through the pain is pretty limited, and that urge to stop is likely just the collapse of your body’s ability to metabolize fuel at a rate needed to continue. It’s not merely a subjective feeling to be overcome.
Like everything else, organized sports have been cancelled due to COVID-19. This includes all the bike races sanctioned by Cycling Canada and USA Cycling. UCI World Tour races have been cancelled, and the Summer Olympics is also postponed. Those who were planning to race might find themselves wondering whether their training this winter had a point. They might also be struggling with motivation: why keep up the rigours of training with no racing in the foreseeable future?
Sport and performance art involves skilled movements which must be learned and improved. For example, pitchers throw baseballs, competitive cyclists sprint out of the saddle, and ballet dancers pirouette. Experts who have mastered these movements perform them automatically, effortlessly, and without much conscious awareness of their bodies (but see Toner et al. 2016). But learning or improving a movement requires compensatory adjustments based on bodily feedback: body position must be sensed, deviation from the ideal registered, and adjustments made. The problem is that many athletes and performance artists have poor bodily awareness, making learning new movements a struggle.
