  • I think DeGroots work in the 30s and 40s shows otherwise. Grandmasters know rather quickly what they were going to do in general as they orient to the board state. Then they explore a small set of moves and explode them into a few moves into the future and pick the best candidate. Finally, they spend time verifying their selection.

    They have good memories, for sure, but for real game states. This is a quote from Herb Simon, an important early researcher in psychology and computer science:

    The most extensive work to date on perception in chess is that done by De Groot. In his search for differences between masters and weaker players, de Groot was unable to find any gross differences in the statistics of their thought processes: the number of moves considered, search heuristics, depth of search, and so on. Masters search through about the same number of possibilities as weaker players-perhaps even fewer, almost certainly not more-but they are very good at coming up with the “right” moves for further consideration, whereas weaker players spend considerable time analyzing the consequences of bad moves.

    De Groot did, however, find an intriguing difference between masters and weaker players in his short-term memory experiments. Masters showed a remarkable ability to reconstruct a chess position almost perfectly after viewing it for only 5 sec. There was a sharp drop off in this ability for players below the master level. This result could not be attributed to the masters’ generally superior memory ability, for when chess positions were constructed by placing the same numbers of pieces randomly on the board, the masters could then do no better in reconstructing them than weaker players, Hence, the masters appear to be constrained by the same severe short-term memory limits as everyone else, and their superior performance with “meaningful’ positions must lie in their ability to perceive structure in such positions and encode them in chunks.








  • I like cruising. There’s nothing like a state highway in the US that’s popular enough to be well maintained, but not so popular that it’s crowded and in the suburbs. They whisk you past some amazing sights and pieces of Americana that are quickly fading.

    As for commuting, anything more than 20 minutes one way is either hell or a trip needing some level of planning between walking to the fridge and sending man to the moon.




  • Shawn Fain is the president of the United Auto Workers union. He successfully negotiated higher wages and better benefits for his member in 2023 after calling for and receiving authorization for a strike. He continues his efforts to unionize more shops and floated the idea that other unions have their contract expire in 2028 when the UAW contract expires.

    He was on Meet the Nation this past week and when asked “Let’s start very simply on the question of tariffs on autos and auto parts. Fundamentally, and quite simply, why do you believe those are helpful for your membership?” This is what he said:

    [A]ll you have to do is look at the history of the United States, especially in auto manufacturing in the last 30 years, with the inception of NAFTA and unfair trade laws. We’ve seen over 90,000 manufacturing facilities leave the United States. We’ve seen- in the Big Three alone, in the last 20 plus years, 65 plants have closed. You know- And so look, tariffs aren’t the total solution. Tariffs are a tool in the toolbox to get these companies to do the right thing, and- and the intent behind it is to bring jobs back here. And, you know, invest in the American workers. The American working class people have been left behind for decades, and they’re sick of it. You know, it’s a massive struggle. People are struggling just to get- to survive right now, to get by. And so, you know- you know- you know, there’s two parts to the tariffs though. I mean, the tariffs are a motivator. We have to fix the broken trade laws. And the other thing to me is, you know, these can’t just be just, you know, as with the Biden administration, when they did the stuff for battery work and EV work, we had to come in and say, no, these can’t just be union jobs or- or jobs. They got to be good paying union jobs that set standards. So the big part of this that gets left out a lot of times is, if they’re going to bring jobs back here, you know, they need to be life sustaining jobs where people can make a good wage, a living wage, have adequate health care and have a retirement security and not have to work seven days a week or multiple jobs, just a scrape to get by, paycheck to paycheck.

    He goes on to agree with “Peter Navarro, a top adviser to the president on trade, says currently, automobile manufacturing plants are at about 60% capacity. He argues that there’s lots of untapped capacity, meaning jobs could be created relatively easy, and you didn’t have to need- you wouldn’t need to spend two or three or maybe five years building new factories.”

    So I’m glad to hear that the UAW and their membership may be well positioned, but the increase in prices will result in inflation and that’s bad for all people including his members. Guess what we don’t buy when we aren’t sure how much groceries or everyday items will be … Cars? Yep. Cars.







  • I agree with the OP’s response. It was well written and gave you several options. In particular, the point about cultural expectations sounds like the most pertinent. I don’t know what your working relationship is with your director, but the fact that they first apologized and second, when they understood your motives, lauded you.

    It does suck having your good faith questions misinterpreted. However, it’s unclear what your director did or said that made you feel you were kissing his ring. Did he scold you? Or just explain how he felt about your question?

    Others have given resources about coops and flat heirarchies, but this sounds like you want a very specific corporate culture. Even in the right fit, you are influencing people and will have to work with their personalities. Politics will always be part of the game as long as there are limited resources and risks in allocating those resources.
