This great excerpt from The Gulag Archipelago by Solzhenitsyn gives insight into the game theory of lavishing praise in dictatorships:

Reminder that sports commentaries are narratives largely built on randomness.

This cute video shows how tail wagging is a way to communicate.

A great way to realise the sheer quantity of information our 🧠 seamlessly processes when we do a “simple” task like driving a car.
This is what the Tesla autopilot sees using a neural network which took 70,000 GPU hours to train.

NFL games’ broadcasts are 1h30 longer than football (soccer) games and they have three times less actual playing time: 18min vs 58min.

Incredible de facto social science experiment. Collective honking resets red light countdown to more time.
Will it reduce honking? I think so twitter.com/sandeepanand12…

We find that the pattern of momentum predicted by the model for male players. It suggests they don’t play all points 100%.
But your insight is interesting! Players could be closer to playing 100% when the stakes are higher relative to effort costs: e.g Grand Slam final.

Consider two equal players. The value of reaching 30-30 is *less* than half the value of the game because players have to expend costly effort.
Then:
At 40-30 the stake is
V(win)-V(30-30)>V(win)/2
At 30-40 the stake is
V(30-30)-V(lose)<V(win)/2
We develop this in the paper.

The asymmetry comes from the stakes players are competing for. The stakes are higher for the player ahead at 40-30, than for the player at 30-40.

Thanks for the reference. I find the Rawls/Harsanyi rule-based behaviour compelling too.
What do you think?

It comes from an asymmetry in incentives.
When you are ahead at 40-30, a win gives you the game.
At 30-40, a win gives you a tied score where you’ll still have to work harder to win.
So the payoff of effort is larger for the player at 40-30 than for the one at 30-40.

Yes that is right! A server at 40-0 is less likely to be caught up than a receiver at 0-40. So the point is more important for the receiver.

Yes they are (roughly).

Indeed 6-6 is key for the tie-break.

So if you find yourself on a court, or watching tennis, remember: the most critical points are most likely 30-30 and deuce.
It’s an insight from game theory which goes beyond the case of tennis and tells us something about the dynamics of competitions.
