We live in an attention #economy & what #Tweetiatricians have known for decades (#Twitter started in 2006): importance of drawing attention to factual science-based information as compared to #misinformation & #disinformation, especially on #vaccines

You have to be fast & prolific to play catch up to this. I have 77K tweets, a moderate sized band of 6K followers interested enough to tolerate my volume but use of hashtags allows reach across Twittersphere. Trending hashtags = better for riding a way for that attention economy Image
If is unclear if we are now so siloed that tweets are ineffective with anti-vaxx. But not all anti-vaxx are QAnon

The computer science maxim "garbage in, garbage out," (#GIGO) dates back at least as far as 1957. It's an iron law of computing: no matter how powerful your data-processing system is, if you feed it low-quality data, you'll get low-quality conclusions.

And of course, machine learning (AKA "AI") (ugh) does not repeal GIGO. Far from it. ML systems that operate on garbage data produce garbage predictive models, which produce garbage conclusions at vast scale, coated with a veneer of algorithmic objectivity facewash.

The scale and credibility of ML-derived GIGO presents huge risks to our society in domains as varied as the credit system, criminal justice, hiring, education - even whether your kids will be taken away by Child Protective Services.

As I keep getting angry message claiming this was deliberately quoted out-of-context (which it was not; I forgot what I thought, but I guess I just found Dr. Drosten's blunt #hyperbole mildly-interesting), I will now present an extra-extensive superset, longer towards BOTH ends.
[Dr. Drosten:] "We don't expect a vaccine before the #US, uh, #elections. Uhm, we have―
[Dr. Barker:] *laughs*
[Dr. Condit:] *laughs*
[Dr. Racaniello:] *grimaces*
[Dr. Drosten:] *laughs* "Well, we expect a #vaccine before the next GERMAN electionswhich (will be autumn next year)>
> *laughs heartily*
[Dr. Barker:] *laughs*
[Dr. Racaniello:] *laughs*
[Dr. Condit:] "So, I'm curious about the #NBA-vaccine. If you know any details: is it just ›spike‹, or does it have other antigens in it as well?
[Dr. Drosten:] "No, spike. This is a spike-based vaccine."

Thought for the day:

All models are wrong. Some models are useful. But to be really useful, models must be based on accurate data, and a clear understanding of the processes being modeled...

Unfortunately, those two key fundamentals are frequently NOT met. #GIGO
Here's an introduction to the "known unknowns" that a "good" model of any pandemic (let alone COVID-19) would include. fivethirtyeight.com/features/why-i…

After a quick photo op with the @DSP_SPE #scipol #NextGenCanSci #dreamteam, I'm attending the #CSPC2018 panel @sciencepolicy on the social implications of emerging technologies w/ @ideas_idees @SocMedDr @emmeslin @Scienceadvice
Discussion questions for 2-way Q&A at the emerging technologies panel #cspc2018 ⬇️
Directions: There are some questions that are easy to answer, others that are more important that are harder to answer (@emmeslin). The social implications of new tech, esp if algorithms can exponentially increase biases and misinformation, are the latter (@SocMedDr) #CSPC2018
