Here we go, folks! The first talk (of those that I'll be trying to livetweet) at #SoCIA18: "Logic, Ethics and History: the Mistake is Thinking It's a Mistake," by Daniel Wueste.
How will alien contact change our understanding of ethics, logic, and history? People think logic and ethics as having some kind of fixed rules. We ask questions to fit things into our heuristics. ("Is it conscious? If so, rational conclusion is...")
But people really like the idea of getting objective, rational certainty. Even though it's mostly a fairytale.
One theory is that moral reasoning is mostly ex post facto - one has intuitions, makes judgments, then reasons afterward. But this produces a false dichotomy. Like in law, where judge decisions are seen as "law" or "judicial fiat" like it's an either-or.
Rational/legalistic arguments are good for communicating and explaining. But, as with any argument, it's vulnerable to argument from authority - where the forms of authority become more important than the content.
"You can give any conclusion a logical form."
Idea (from Oliver Wendell Holmes) that there's a "vital logic" that stands behind, and leads to the creation of formal/legal logic. The logic of inquiry, as opposed to the logic of exposition.
Despite the archaic 1920s term of "vital logic," these two types of logic aren't exclusive, but complementary. We need to know BOTH what caused the conclusion and what justification can be provided.
I want more aliens in this talk, alas.

Handedness comes in two groups, "right handed" and "not right handed." Most people use their right hands for almost all precision movement, but the other group is a broad spectrum from weakly-right to strongly-left. baen.com/handedness
The way we describe and define handedness creates the effect @CStuartHardwick rightly notices. Culture defines how we talk about it - but the behavior is mostly genetic. The % of righties has remained constant across continents and milennia.
Hand dominance is a more squirrelly thing than most people realize. For example, righties are better at *some* things with their left hand... and *some* of these asymmetries flip in lefties. Take a few minutes on #LeftHandersDay to learn more!
But you should read and learn from the #BlackSpecFic report anyways! The missing data is due to idiosyncrasies of the @EAPodcasts model, and has no impact on any other magazine's numbers.
Long story short, we treat reprints very differently from other magazines. For @escapepodcast specifically, they were ~45% of our 2017 stories, and our editorial process has one unified pipeline for originals + reprints together.
Regretting organizing my two Worldcon panels this year. It means I'm not free to throw up my hands in frustration and give up on programming. The last 24hrs have been the last worst icing on a bad cake that's long been baking.
I mean, my panels will be awesome. But if you're skipping programming because you don't trust the con, you've made a sensible choice.
There are always more people who want to be on programming than can fit. There's no way to make everyone happy. I get that. But this weekend's screwups come in the context of a long chain of trust-erosion.
So glad this one came out! "After Midnight at the Zap Stop" by @ouranosaurus is an awesome story - full of late-night grease, and the luckless & the worthy. But also because it's a #neuroscience teaching opportunity. Might even be a #NeuroThursday!
One offhand line explains a technology as "stimulating a particular set of mirror neurons." Which works as a story element just fine. It sounds plausible and authoritative! But as a neuroscientist, I have strong opinions about #mirrorneurons. I don't think they're real.
To be clear, mine is a controversial opinion. Many neuroscientists would disagree. But it's a hill I'm willing to fight on, especially given how often "mirror neurons" crop up in popular science.
This phenomenon - when you look away from a moving thing, and you briefly see illusory motion in the other direction - is the "Motion Aftereffect," and it comes from some very basic brain maneuvers. Who wants to join me on going full #NeuroThursday here? en.wikipedia.org/wiki/Motion_af…
Most neurons in the brain (and elsewhere) do this thing called "adaptation," where they accept whatever's going on as the new normal. For example, if you sit down with your laptop on your lap, you'll soon stop noticing the weight.
This can arise from the crudest single-cell level: some ion channels in the cell membrane have negative feedback loops that self-dampen.
