If independently validated, an 8% decrease in sharing of false information is a big deal.

Someday companies will routinely be required/expected to share results of their experiments on us, rather than journalists leaking results. By @CraigSilverman

Think how big an effect an 8% sharing reduction would be, if real (withholding judgment without details).

A platform data scientist is claiming they can reduce sharing of statements by a person with a huge megaphone, whose tweets are newsworthy, & who has a committed base 😮
Debates on online discourse have a baseline problem. It's impractical & undesirable for 0% of a head of state's comments to reach the public. But 100% isn't great if they're false.

That's how policy debates get stuck on arguments that a firm could "do more" & real wins get lost.
What's the way out of this dilemma? Focus on finding policies that work by looking at their *effects*. If companies committed (or were forced) to report their research results, we could celebrate wins and move on from duds.

The most frustrating part of the this story is how @CraigSilverman & others are reduced to cobbling together guess-timation math without enough evidence to evaluate corporate claims. Is 80% better than 8%? It's literally impossible to tell without more detail.

Most large online communities have coordinated across multiple platforms for years. While quarantine/bans can disrupt recruitment, they just displace the core group elsewhere.

This piece by @alibreland shares a notable example of this. motherjones.com/politics/2020/…
A few years ago, @TarletonG and I were talking about whether we need to see conten moderation through the concept of assembly as well as speech. It's high time.

By focusing on speech, people have mistaken social/cultural problems for a content problem. And here we are.
In the 18th century, freedom of speech & assembly represented social functions that have now become un-bundled & repackaged online. To name a few:
- spreading ideas
- connecting/recruiting
- raising funds
- building relationships & group identity
- coordinating groups to act

Is support for black lives short-lived? Can movements that organize around events like the death of George Floyd lead to long-term change?

Last year, @EthanZ @rahulbot @fberm @allank_o & I published research on news & social media attention to black deaths, 2013-2016. Thread:
How does an ignored, systemic issue become newsworthy? Comm scholars sometimes describe news coverage as an ocean of overlapping "news waves." Some waves, like sports, have a natural cycle. What about issues like police violence that somehow don't get much coverage?
Kepplinger & Habermeier (1995) proposed that "key events" like an earthquake or a string of deaths can "trigger waves of reporting on similar events." To test this idea, they studied German news on deaths from earthquakes, AIDS, & traffic accidents—before & after key events.

Tidying up, I find a diagram of wisdom from @xuhulk when I was a gradstudent. At the Media Lab, the risk was always to err too far on the side of promotion. But many researchers under-promote.
I remember being told once that researchers should let the scientific process decide the value and attention our own work deserves and receives.

It's a valuable principle when deciding what to amplify. I wish the system worked reliably that way.
My priority in promotion is usually *utilization* - I hope my research will be useful to the people it matters to. That requires different effort from sharing findings with other scientists. Carol Weiss offers a great intro to the idea of utilization acawiki.org/The_Many_Meani…

Are clinical trials morally justifiable if they withhold treatment from some people?

Today in class, we discussed "equipoise," the idea that the benefits/risks of tests should be grounded in scientific uncertainty rather than any individual's certainty nejm.org/doi/full/10.10…
In class, we discussed chloroquine, which some people believe should be administered now for covid-19 rather than tested in clinical trials. With HCQ, there's huge equipoise- we don't have enough evidence to know its benefits or side effects
We also discussed the essential role of informed consent. Sometimes people take big risks to advance knowledge. If "human challenge" studies are approved, volunteers would agree to be infected with covid-19 to dramatically speed up the search for a vaccine

Was planning a five-day trip to NYC this week for a conference & retreat and have decided to cancel, to do my part to slow things down. Sorry not sorry everyone!
Thanks to @alexismadrigal for helping me see that I shouldn't try to make decisions based on the overly-low official statistics bit.ly/38n6wIq
Thanks also to network scientists and epidemiologists who reminded me how fast things can spread. For example, @NAChristakis offered helpful thoughts about comparative value from early preventive measures that helped me avoid brinksmanship with my own risk

Today I realized hermit crabs are the *cutest* illustration for the Threshold Model of Collective Behavior, described by Mark Granovetter in 1978. First, the crabs

Granovetter argued that if you want to explain behavior, you need an understanding of individual psychology combined with "a model of how these individual preferences interact and aggregate"
Writing about diffusion of innovation, rumors, strikes, voting, riots, & other phenomena, he imagined people who each have a personal "threshold" for acting before doing so. One person needs to see 2 people vote before they will; someone else needs to see 10
