My basketball hoop comes with incentives to be a better shooter. Make a swish and nothing happens. Anything else and there is a non-trivial probability of unleashing a horde of angry wasps.

This was a fun 3|2 blitz game. The analysis gave me !! for 18. ...hxg4, but why wouldn't I want to open the h file? That was the point of h5 two moves earlier.

Data scientists: beware of accidentally manipulating your data! It looks like people in Costa Rica like my YouTube channel (highest average view duration) but it's only because I was just there for a conference.

Here's the word cloud of the titles of my papers on Google Scholar, which can be generated for you at ScholarGoggler dot com, h/t to @RonCheung42. If nothing else, you can tell I'm an experimental economist! #EconTwitter

I’m impressed with this picture I somehow took today (iPhone 12, portrait setting)

Could economic modeling help our health care system address chronic pain? This thread is a description and analysis of the model swimming in my head after having a frustrating experience with a medical specialist. #econtwitter 1/n

7. With Policy 2, doctor anticipates x2*=argmax{(-A+Bx)(1-y) - 1/2*x^2}=(1-y)B. Because all parameters are known, the doctor can implement the socially optimal treatment y** and it’s left as an exercise for my students that y** = P/(2T-B^2)

8. Conclusion: Policy 1 gives y*=P/2T, Policy 2 gives efficient y**=P/(2T-B^2) which is increasing in B given P. Doctors should recognize endogeneity of mitigation when using pain as diagnostic tool and consider how patient’s life is affected by pain mitigation. (Mine did not)

I'm an Econ professor and today when I learned the ages of the children of our Dean I immediately remarked to her that their ages are a mean-preserving spread of my kids' ages. Embarrassing or impressive? #EconTwitter

Today is the last (and most important!) round of play at CollegeFootballRisk.com where individuals choose to defend a territory or attack one that your team borders. Consider playing for Ohio State and attacking one of the blue territories owned by Michigan!

🚨FINAL DAY🚨 TODAY IS THE DAY!!! Beating TTUN is now or never. Tell your friends, tell em to tell their friends, retweet this, it takes 30 seconds to go attack a blue territory and pull off the upset. SHOW EM WHO THE BEST DAMN FANS IN THE LAND ARE #OhioState #Buckeyes

After 100 Wordles, my family is averaging 3.86 guesses per Wordle. Wordlebot says the optimal strategy results in 3.4 guesses in expectation, so we have some room for improvement.

We hit 200 Wordles. Our average score is now 3.785. It's a small improvement that can likely be attributed to imitating Wordlebot's optimal strategy.

We made it to 100 straight days of solving the NYT crossword. Solving them together, as a family plus whatever guests we happen to have, has been pretty cool and I wonder why we weren't doing it before.

Our streak ended at 365 days. It was fun, but after a year we're thankfully switching to a policy of *optional* daily NYT crossword puzzle completion.

It's here–the deepest, sharpest infrared view of the universe to date: Webb's First Deep Field. Previewed by @POTUS on July 11, it shows galaxies once invisible to us. The full set of @NASAWebb's first full-color images & data will be revealed July 12: nasa.gov/webbfirstimages
The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center.

Senator Chris Murphy (@ChrisMurphyCT): "The 14 kids dead in an elementary school in Texas right now. What are we doing? What are we doing? Just days after a shooter walked into a grocery store to gun down African American patrons we have another Sandy Hook on our hands."
