I’ve just tuned in! Very interesting so far! (Lee McIntyre is terrific!)
2/ Fascinating re the tobacco companies in the 1950s; @LeeCMcIntyre explains how they managed to convince journalists to tell “both sides” of the smoking-and-cancer “debate.”
3/ The scariest part of science denial is how it has spilled over into reality denial, says @LeeCMcIntyre.
4/ People will believe almost anything if their identity is at stake, @LeeCMcIntyre says.
5/ Many science deniers change their minds once they meet an actual scientist, says @LeeCMcIntyre
6/ Panel discussion just beginning: why and how mis- (and dis-) information spread. Moderated by science journalist @alexwitze
7/ Panel includes @surveyfunk, @STWorg, and Ziv Epstein. Current topic: the global spread of misinformation.
8/ It takes a lot of cognitive effort to change one’s mind about something (to un-believe something), says @STWorg
9/ We’re hard-wired to believe what we see and hear; very young children struggle with the idea of deception, says @STWorg (This partly explains why it’s hard to dis-lodge misinformation from our brains)
10/ Fascinating topic: can people be inoculated (so to speak) against misinformation? @STWorg discusses his research into this. (Oops should have been using the #scicomm tag all along)
11/ But it would be wrong to place the burden on the end-user: There are systemic / structural issues, and the tech companies have to be held accountable, says @STWorg .
12/ @STWorg recounts the tragic case from India, from a few years ago, when dozens were killed by lynch mobs due to misinformation spreading on WhatsApp. (cont’d)
12b/ The platform implemented a number of seemingly-small architectural changes, which made a huge difference. (At least, the mob killings stopped, thank goodness) (But still: yikes)
13/ In the old days (say, 150 years ago) if you believed something crazy, you would likely not meet anyone else who shared that belief. But thx to the Internet, you will now immediately meet 100 like-minded people, says @STWorg (and this will reinforce your belief)
14/ People’s beliefs are shaped in part by facts — but also by values and by emotions, says @surveyfunk (which is part of the reason that “piling on more facts” doesn’t always get you too far)
15/ “Don’t mistake your Twitter feed for reality.” — Great quote from @STWorg to end the panel discussion. (Also kudos to @alexwitze for moderating!) Event continues after a 15-min break…
16/ Next panel: “Misinformation’s impact on science and authority” w. @nabihasyed, @jevinwest, and @KatieLSanders. #science #scicomm
17/ Fascinating to hear @nabihasyed on the legal challenges of confronting purveyors of fake news (even “harmless” fake news) in the courts…
18/ Astounding evolution of the marketplace in recent years: Corporations can now “frictionlessly” reach out to millions of people who show an affinity for, say, this or that type of nonscientific belief, explains @nabihasyed #scicomm
19/ Yes, 1A — but listeners have rights too, @nabihasyed reminds us. Maybe something like the “fairness doctrine” needs to be resurrected — or something, so that consumers don’t drown in a sea of bogus “news.”
20/ Not an update per se, but holy heck I am blown away by the breadth and depth of the expertise on this panel! (@KatieLSanders, @nabihasyed, & @jevinwest) #scicomm
21/ It’s really east to spread BS, and *a lot* harder to clean it up — but we need to narrow the gap, says @jevinwest #scicomm
22/ @nabihasyed outlines the (many!) well-established limitations on free speech (in the U.S. context). The first amendment doesn’t mean that anyone can say anything anywhere anytime.
23/ “The future of media literacy is numeracy.” — @nabihasyed #scicomm
24/ @jevinwest on the paywall dilemma: Media outlets need revenues to exist; but if people turn to free “news” as an alternative, that can have repercussions. #science #journalism #scicomm
25/ @jevinwest: Often the goal of mis- (and dis-) informs campaigns is simply to erode trust in institutions. (And, unfortunately, it’s working.)
26/ Pause for “lunch.” Big thanks to @InstituteSciPol for organizing this; I’ll try to catch as much of the remainder as I can! (And thx to @alexwitze for mentioning it on Twitter!)
27/ Sadly my internet connection conked out during @Imi_Ahmed’s talk, but the parts that I caught were terrific. Anyway, that seems to wrap it up for today; kudos again to @InstituteSciPol!

“The good journalism has gotten better, and the bad journalism has gotten a lot worse.” — @picardonhealth summarizing how #science #journalism has changed since 1987, in tonight’s @RCIScience event, underway now.
2/ @picardonhealth cautions against “false balance” — the all-too- common practise of pretending that two opposing points of view are equally valid (which is especially problematic in health & science reporting). #scicomm
3/ “Take the time to do it right.” — @picardonhealth says it really doesn’t matter if his story comes out five minutes after, say, the TO Star’s version of the story. “Only journalists worry about that.”

1/n #Hanukkah comes super early this year – it starts tonight! – and in fact, this is the earliest that it *can* occur. Let’s talk about why that’s so! (thread 🧵 ) #Hanukkah2021
2/ The date of #Hanukkah is determined (no surprise) by the Hebrew calendar, not by the Gregorian calendar. More specifically, Hanukkah begins on the 25th day of the Hebrew month of Kislev...
3/ The Hebrew calendar is “lunar-solar,” which means it uses months based on the cycle of the moon’s phases, but also attempts to synch up with the annual cycle of the seasons…

1/n According to numerous colleagues on Twitter, Nobel Laureate physicist Steven Weinberg has died. He was a towering intellect. I'm sure much of the coverage to come will focus on his contributions to science, but (cont'd) (Photo: Jeff Wilson/The Guardian)
2/ ...he was also a first-rate science communicator. His books, and his essays in the @nybooks, were illuminating and authoritative, regardless of the topic.
3/ This is perhaps the most famous -- or infamous? -- thing that he wrote:

No-one: Dan, I see the donut-shaped universe idea is back in the news. Didn't you write about that in the last century?
Me: Yes; yes I did. A big eight-page spread in @SkyandTelescope, July 1999, on the topology of the universe: (#space #physics #donuts) Image
And look how they wrapped the headline around the first double-page spread, Pac-Man style. Pretty neat (and apt)! Image
And actually it all started (for me, anyway) with a workshop that @gstarkman organized at @cwru back in 1997. Good (and simpler) times!

1. “The Death of a Universe” -- Terrific talk this evening by Dr. Katie Mack (@AstroKatie) at @yorkuniversity. Here are a few highlights. This of course is the CMB, the faint microwave “echo” of the big bang. (cont’d) #physics #astronomy #cosmology (@YorkUScience)
@AstroKatie @yorkuniversity @YorkUScience 2. The big bang happened ~13.8 billion years ago. So what lies ahead? Could the universe collapse in a big crunch? Maybe – but as Prof. Mack explained, it's more likely that it will keep expanding. In fact, the universe is currently not only expanding but also accelerating...
@AstroKatie @yorkuniversity @YorkUScience 3. We seem to live in a universe with a non-zero cosmological constant. Right now, the CC appears small – but in the far future, the CC could come to dominate. That won’t end well! At best, in that scenario, we’re going to freeze to death in the dark...
