This has to be a cover story - there's no way Giuliani and Lewandowski planned it there originally. Totally implausible. There are lots of places in the Philly region where people wouldn't be cheering.
I'm told it's near NE Philadelphia Airport. Possibly convenient for Giuliani if he's getting on a private plane? Still, other options than in front of a landscaping business
Between an adult bookstore and a cremation center!
New @nature: Like-minded sources on Facebook are prevalent but not polarizing
(open access!)
Our key findings:
-Median FB user gets 50.4% of content from like-minded sources
-But reducing exposure by ~1/3 for 3 months had no measurable effect on attitudes https://t.co/IpaHQ0bnGznature.com/articles/s4158…
Increased polarization and hostility are often blamed on echo chambers on social media.
We therefore look at the sources people are exposed to on Facebook to see (a) how slanted they are toward people's political leanings & (b) what effect changing those sources would have.
We estimate user political leanings with a validated classifier and categorize other users, Pages, & groups as "like-minded" (sharing user's leanings), "cross-cutting" (on other side), or neither (in the middle). Exposure data are June-Sept. '20, experimental data Sept.-Dec. '20.
Next I pressed ChatGPT to make synthetic @j_a_tucker, @AdamBerinsky, @emilythorson, @AliceMarwick, & @duncanjwatts more critical & to draw on specific research. Again not nearly as good as the real folks but how long until we're evaluating R2 on value above ChatGPT (VOCG)?
Here's a review written by synthetic me. I gave my paper an R&R, which I guess is a good sign?
Academics: Papers that say they are preregistered must (a) attach the prereg as filed and/or (b) provide a working link to the full prereg. Anything else should be bounced by the journal or rejected by reviewers. Otherwise prereg just becomes a totem people invoke w/no content.
I ran out of room but this too! Reviewers HAVE to look at the prereg. Writing down a few vague hypotheses and then saying the whole study is preregistered is not a preregistered study. Telltale signs: lack of description of deviations & what is exploratory
If you are an editor or on an editorial board, you need to include these checks in your post-submission workflow. Don't let papers get to the review stage that don't provide full preregistration information if they claim it!
