Capitalism is not the core philosophy of evolution

Abe Drayton, who appeared in last Sunday’s hangout, has a fine article centered on Mexie’s discussion of the injustice of capitalism towards disabled people. You should watch it, but also read Abe’s commentary.

Capitalism relies on the lie that human nature is all about greed, competition, and aggression. That is not what drives civilization, it’s what constantly tries to dismantle it. Every advance we have made in human wellbeing has come from the mass of people working together against those obsessed with competition and power to create a world that’s better for everyone. Capitalism does not give a damn about you, but fortunately those obsessed with capitalism are wrong – it is not an inevitable result of human nature, it is a perversion of it. A better world is possible, and we can move in that direction the same way we always have – by expanding the “tribe”, by pooling our resources and efforts, by caring for each other, and by using our collective power to force change.

Lay people seized upon Darwin’s idea of natural selection to distort it in directions favorable to capitalism, and started a dreadful feedback loop that justified exploitation — “I’m rich, therefore I deserve to be rich by natural law, and you’re poor, so you don’t deserve what little you have” — and ballooned it into a rationalization for our current nightmare. It’s what allows creationists to caricature evolution as nothing but a history of death and suffering.

It’s more mainstream than that, too…the whole idea of “Darwin Awards” is terrible and unrepresentative, unless you also give the award to individuals who increase the success of others and themselves with generosity and cooperation. The human species did not succeed because they were the best at killing — they’ve always improved our common survival by working together and building communal social structures.

More serious analysis of online conferencing, please. It’s our future.

You’d think that after a long period of isolation I’d be looking forward to a return to normality and the opportunity to mingle with others at a conference again. Strangely, I am not. There are great things about real-life conferences, but also great awkwardnesses. I stopped attending the annual Society for Neuroscience conference many years ago as attendance soared past 20,000, which made the face-to-face appeal diminish as we became a faceless mob…and also as it became obvious that a subject as complex and diverse as neuroscience couldn’t be appropriately managed in a one-size-fits-all event.

So I thought this article about organizing scientific conferences online was somewhat informative. I’ve been involved in running a social justice conference online, once upon a time, so I’m familiar with some of the compromises, but it’s good to see some new ideas. Zoom has all kinds of potential, and they used Crowdcast, but I thought the way they applied it was a good mix of traditional and novel uses.

Even the traditional elements were improved.

We largely retained the legacy conference format of a single track for invited talks (30 minutes plus 15 minutes for questions) from established scientists, and contributed talks (18 minutes plus 4 minutes for questions) selected from the submitted abstracts to highlight work from up-and-coming researchers. However, the online platform used – Crowdcast – allowed for some significant innovations. First, everyone was able to see the speaker more clearly than in a lecture theatre. Second, Crowdcast allows anyone to submit a question to ask the speaker at the end, and viewers can vote on those questions. This led to a question and answer session that was considerably more lively and democratic than in a typical legacy conference, where participants often note that the same established professors are asking the same questions at every talk. As in the case of the short talks, it may be better to extend the questions even more to capitalize on the quality of the questions asked in the safer and more democratic online format. The third innovation is the chat window that appears alongside the talk. We did not anticipate how significant this would be. Students and others were able to ask basic questions about definitions or ask for links to papers while the talk was going on. Other participants could answer them in real-time without disrupting the presentation, thereby allowing a deeper level of engagement by the audience than is possible in legacy conferences. Moreover, since recordings of these talk were available immediately after the session, it would be possible to go back and revisit portions of the talk that may have been missed or were presented too quickly.

Right, you’ve got to keep the talks limited to familiar blocks of time. We do a lot of training and practice to maximize information in small specified chunks of time. They didn’t do one hour talks, though? I’m used to conferences with plenary sessions with hour-long time slots for bigwigs in the field…they usually don’t live up to their billing, though. An hour is a long time to fill.

The other thing you need for a conference is the schmoozing. They had a way of doing that that seemed to me to be trying too hard. Typical nerds.

One feature of a legacy conference that would appear to be impossible to replicate online is the social aspect: chance encounters during the coffee breaks, social events or banquets. In place of this aspect, neuromatch algorithmically matched attendees to other like-minded scientists for individual 15-minute chats. We use a combination of topic modeling techniques and linear programming to solve the matching problem based on a sample of their research abstracts (Achakulvisut et al., 2018). The matching part was based on a highly popular experiment carried out at the Conference on Cognitive Computational Neuroscience, but it is particularly well-suited to an online format. There remains considerable scope for further innovations in replicating or improving on the social experience of legacy conferences, especially as the online format may be less socially intimidating.

Wouldn’t it be easier to just randomly put people into small break-out groups? This sounds too planned — one of the benefits ought to be serendipitous encounters using a simple algorithm that assumes every participant is equally interesting with unique attributes that anyone might find productive. One useful parameter I wanted to know is what is the optimal group size for these chats. Was it one-on-one? Half a dozen in a group? Small classroom size with 30 participants?

I suspect that one good thing that will emerge from this pandemic is more online conferences. It vastly reduces the expense, gets rid of the bother of air travel, and helps participants manage their time better. I currently try to attend one conference a year because it’s such a huge investment of time and effort — and this year the one I’d planned on got cancelled, of course. But if they were online, I’d be able to schedule that arachnology conference, the Society for Developmental Biology annual meeting, and SICB every year without killing myself with constant travel to the airport, while still learning new things and engaging with new people. Make it so, scientific societies!

Also, if you’re interested, Skepticon is going online this year. I’ve long wanted to attend Dragon*Con, but it’s been impossible because it always falls during the first few weeks of classes, when I can’t possibly just take off. Of course, if it went online, what would happen to all the cosplay events? And now I want to attend even less, because it’s held in a state where Brian Kemp is the Republican governor who is mismanaging the pandemic, and we’ll probably see another wave about the time Dragon*Con opens for business as a big bustling petri dish. Many Shubs and Zulls will know what it is to be roasted in the depths of a Sloar that day, I can tell you!

I wonder if they’re even considering alternatives — I get the idea that our regional SF con, Convergence, is going ahead with the idea that they’ll be doing business as usual in late August, while developing contingency plans. I’m not so confident. Getting crammed into a single building with thousands of other attendees, many of whom need to be reminded about the basics of hygiene, seems to regularly lead to icky cases of con-crud. Only this con-crud can kill you!

P.S. I’ve only just noticed that searching for “online conferences” produces strange images of people sitting around a conference table staring at a screen on the wall, or the always-popular image of two people shaking hands through a pair of computer screens. I really don’t think they get it. That’s not how it’s going to work, or can work. And shaking hands? Is anyone else feeling repulsed at the idea of physical contact with some stranger’s filthy hands?

Australian rules

I’ve been wrestling with spider taxonomy, and I hate it. Hate it, hate it, hate it. You finally learn to recognize a common spider, and somebody comes along and turns the nomenclature upside down…like this recent case, where the genus Sitticus gets revised to be called Attulus. There’s good reasons for it — detailed molecular phylogeny clarifies relationships — but it’s still infuriating. I remember when Brachydanio rerio was revised to Danio rerio, and I’m still reading papers about Achaearanea tepidariorum despite the fact that we’re now supposed to call it Parasteatoda tepidariorum (at least zebrafish got revised to a shorter, easier to pronounce name).

So screw it. I’m just going to have to adopt the Australian rules for naming spiders.

Morning spider survey

I did my usual quick survey of spiders on the outside of my house. The place is swarming with salticids! Mainly Attulus and Salticus. I’ve done the usual thing of posting photos on iNaturalist and Instagram and Patreon, if you really want to see them. They really like the masonry on the east-facing front of the house, where the stones warm up fast, but I found them all over the place.

How to explain to someone that they’re wrong?

This Sunday at 3pm Central I’m convening a small group of my Patreon patrons and FtB bloggers to have a science-based conversation about all the pseudo-scientific nonsense floating about.

What I’m hoping to do is much more than just sneer at stupid ideas, but to talk about how we can persuade and inform people about why some of their ideas are bad, and what are better approaches. Let’s put together some positive science communication!

The compost bins are coming alive!

I got word from a colleague* that their compost bin was accumulating spiders again — they had a swarm of them last spring, that disappeared over winter — so I had to check it out. I opened the bin and was disappointed at first, because while I saw lots of cobwebs all over the decaying vegetable matter, there was nowhere near the number of spiders I’d seen in the spring.

I finally spotted one in a corner. Steatoda borealis, the same species that had thoroughly colonized the bin before.

Steatoda borealis is an interesting theridiidid. They seem to be the native species to this area, with the more common house spiders being immigrants from either Eurasia or South America, depending on the species. These beasts are bigger than the others, and I haven’t seen them in houses or garages much, mainly outdoors or in special environments like this compost bin. I’ve got some in the lab, and they seem less active than Parasteatoda or Steatoda triangulosa, but that may be because I’ve only observed them in the day.

I spent several moments poking around in the bin, taking a bunch of photos, making a note to myself to come back in a week or two. Then I started to lower the lid. The lid I’d been holding up all this time with my left hand. Only then did I notice that it was covered in webbing, and there were all the spiders, lots of them, gettin’ busy busy beneath my oblivious fingertips. Squeee! Jackpot!

So I had to take a bunch more photos. These spiders were paired off all over the place, mating furiously! I took photos of these wonderful piles of tangled legs, 16 at a time with agitated bodies having a grand time.

You’ve probably heard about female spiders killing their mates and eating them, but that doesn’t happen so much in environments rich in food. Steatoda and Parasteatoda can happily coexist in sprawling web communities where lots of insect life is rising up from a festering mass, and they don’t do the cannibalism thing in those circumstances.

I did notice one lonely male off to the side of a mating pair, staring intensely. I hope you find your true love soon, little guy!

Definitely going back here later. It’s a wild little hotspot for spider orgies.

This post also appears on my Patreon account, complete with spider photos. The photos are also posted on Instagram and iNaturalist.

*A colleague in math. Curious fact: two of the professors in our math discipline have the most interesting spider populations in their yards. Is it something about mathematicians that attracts spiders?

Distract yourselves with pretty moving pictures!

In news to help us drag ourselves out of the slough of despond, the Science Museum of Minnesota is closed to the public. Wait, no, that’s badly phrased — that’s not the good news. The good news is that the Science Museum of Minnesota is making their big screen science movies freely available to the public. Right now, you can just click and watch “Dinosaurs Alive!” and “Mummies: Secrets of the Pharaohs” and “Wild Ocean” on your computer screen.

Your computer screen is probably not a giant dome that you view in front of and above you from a reclining chair, so when the museum reopens you might want to book a visit to get the full experience and thank them for providing the service.

P.S. I’ve seen the dinosaur one, it’ll keep kids’ attention for a while. I’m going to watch “Wild Ocean” myself this afternoon, as a distraction from grading.

The iridescence is pretty, anyway

Here’s what I do. I sit in my office in front of my computer with a pile of textbooks open to my left, and sometimes I have committee meetings over Zoom, or meetings with students over Zoom, and my eyeballs are generally locked on the screen. But I also have a window to my right which looks out over the bird feeder in my yard, and I keep my camera close at hand, and sometimes some feathered beast distracts me for a bit.

Today was a grackle day. They were all over the place. I don’t like grackles much, but I do appreciate the shiny iridescence.

Also, the chickadees are challenging me. They flit in, I raise my camera, they immediately flit away. They are hyperactive little twits who won’t pause long enough for me to get a picture, even at 1/800th of a second. This is the best I’ve gotten so far, and look at it — it’s getting ready to take off barely after it’s landed. I think they’re doing touch-and-gos on the feeder.

At least they’re keeping me semi-sane.

Ignoramus telling scientist how science works

Would you believe Republican Senator John Cornyn had the gall to mouth off about the scientific method? Of course you would, he’s an idiot.

That’s just breathtakingly stupid. Does he have the slightest understanding of what a model is? It’s the core of the hypothetico-deductive process (which is not the whole of science, but it’s pretty essential). He’s been refuted in a couple of places by knowledgeable people already.

In a now-famous lecture, quantum physicist Richard Feynman similarly described to his students the process of discovering a new law of physics: “First, we guess it. Then we compute the consequences of the guess to see what… it would imply. And then we compare those computation results to nature… If it disagrees with experiment, it’s wrong. In that simple statement is the key to science.”

Zach Weinersmith also has a 100+ panel comic describing epidemiology and models if Mr Cornyn needs pictures to go with the words.

If Cornyn actually wanted to have a “good faith discussion” about epidemiological modeling (I don’t believe he does), I have a couple of expectations: as someone who has no training in science at all — he’s a lawyer — he ought to be more humbly asking for information, rather than poisoning the well with nonsense, and he has to admit that the source he worships, Donald Trump, is a total incompetent at science and a worthless font of misinformation. Then we can begin.

Actually, I think I’d rather begin by seeing Cornyn evicted from his office.
