Extremely important finding on birth month and ADHD. TL;DR: August birthday (read: enter school younger) associated with 30% increase in ADHD diagnoses relative to September birthday. But only in states with September school cutoff. @AnupamBJena

This is a fantastic study with an ingenious design. I was born very close to our cutoff, was youngest in my class, and had a questionable dx of ADHD for years. This is the best explanation I've heard. Props @timothyjlayton@ml_barnett@tannerhicks42@AnupamBJena@NEJM
Take 2 kids. One born in Aug & the other in Sept. In states with a Sept 1 cutoff for school entry, Aug-born kids are 35% more likely to be diagnosed AND medically treated for ADHD. Our study w/ @timothyjlayton@ml_barnett@tannerhicks42 in @NEJM

I've been getting used to gganimate and thought it would be useful to put together some illustrations of what various causal inference methods *actually do to data* and how they work. Here, for example, is what it means to control for a (binary) variable

The Benefit of Having the Same Name as a Police Officer
Great working w/ @CassSunstein@tannerhicks42 on @nytimes piece that used speeding tix data to show that prob of getting a ‘mercy ticket’ increases if u have same name as officer that pulls u over

Maybe, just maybe, we should be investing in education rather than locking kids up.
Is 'Vas Madness' real?
We find a 20-30% increase in vasectomies in a large privately insured population on the Wed & Thurs of March Madness week compared to identical days in surrounding 4 weeks. What better time to recuperate?

So, what's our plan? On Friday, April 20th, the 19th anniversary of the Columbine shooting we propose a National High School walk out. Don't attend school, wear orange and protest. Sign the petition on our page if you pledge to do so. #nationalwalkout#schoolwalkout
70 other students and I are trying to arrange a #NationalStudentWalkout campaign to protest against gun violence in American schools and universities. Can you use your Twitter account help us spread the word? @TucsonStar
Students across the nation should hold a national walk-out of school indefinitely until gun laws are changed. Adults can’t accomplish anything... maybe students can give this a try.
One year ago today Hans Rosling died.
To remember him I want to share some links in this thread.
Of the many talks he gave, ’The magic washing machine’ is my favorite.
The quote explains the magic of the machine – laundry in, books out.
Here is his talk

Rachael raises an important point: There is a lot of peer pressure among academics to make it sound like the worst, longest-hours job in the world. I've seen this again and again and again. That doesn't fit my experience at all. 1/x https://t.co/A56sLtkZWj
It doesn’t have to be this way for many of us. I rarely work more than 40 hrs/wk since grad school (when I worked way more hours). Ask @bradleyvoytek too. Not saying others are inefficient w time. I focus on fewer things bc a main goal is keeping life manageable. (1/n) https://t.co/iNYrylz3fI
