The reason this is a disingenuous argument is because it endeavors to restrict the definition of 'thinking' strictly to cognition - or further still, to cognition in the absence of recognition, which is actually quite absurd if you think about it. However, by definition thought has no such restriction - recognition and spontaneous ideas should hold as much weight, and can in fact speed up the process of cognition itself [0].
> The difference between "thinking faster" and shortcutting your thinking to reach a conclusion faster.
I don't see any difference between these two things - perhaps you can elaborate. In my opinion if you can shortcut your thinking to reach the same conclusion faster, you are in fact thinking faster for all intents and purposes.
You start with some of them: A=>B, C=>D, B=>C, E=>F, B=>G.
You now get A, and need to decide which tool is better: D or F. You start the reasoning: A=>B=>G&C=>D. After 4 reasonings you arrive at the solution: D. If you need to do this reasoning several times, you 'learn' A=>D. Now, when you need to make the same reasoning, you do A=>B&D. You get the same output but twice as fast. You 'learned'. Muscle memory is also a very good example of this.
The objection is that spending more time thinking about something doesn’t guarantee more accurate responses. Often people’s first reaction is correct and they second guess themselves into making the wrong choice, thus so called shortcuts are just as valid as any other kind of thinking.
For the muscle memory example try really paying attention to walking and your going to be less stable.
A chess grandmaster knows better than to consider every option to the same depth. Pruning is choosing what not to think about. I wouldn't expect grandmasters improve by increasing their positions evaluated/second throughout their career.
As an amateur chess player (2000/rapid/lichess) I wouldn't say the speed or amount of thinking I do has changed as I've gotten better in terms of the number of moves I evaluate. In fact it feels like I frequently think less now than when I was worse.
My brain has compressed/chunked patterns so that I can immediately see what the optimal move or set of candidate moves are instead of having to determine them more computationally.
I'm not sure how that fits into the framework of this article. Something like the number of calculations remains static but total work done per calculation increases.
Much of the debate in this comment thread is a result of these concepts being fuzzily defined in the article itself.
"Think rate is fixed" glosses over activities with compounding returns. Learning!
Better abstractions and heuristics can have an enormous impact on problem solving efficiency.
First-principles thinking is a powerful hammer, but it's expensive. Over-use it and you'll get nothing done. Under-use it, and you'll do nothing original. Knowing where to use it is the trick, and that's _also_ a skill that can be improved over time.
Chess GMs certainly prune better, but can also evaluate moves faster because they can easily hold multiple boards in their head. It's common for strong GMs to play 10+ blindfold simul games. Nakamura solving chess puzzles is a sight to see.
Doing less thinking to reach a conclusion quickly isn't the same thing as thinking faster.
It's a meaningful distinction because there are physical and mental costs (calories and stress) to trying to "think faster" that don't accrue the same when making decisions based on learnings.
If the process of considering options and reaching the correct conclusion concludes faster and that is our definition of thinking, it should follow that the thinking is faster. Somewhere in your last comment you must've pivoted your definition, because you described it rather as thinking 'less' and saying that it is NOT the same thing as thinking faster. That's perfectly fine, of course, but it left me confused as to what definition you were now using.
It's a shame you've decided to abandon the argument.
> If the process of considering options and reaching the correct conclusion concludes faster and that is our definition of thinking, it should follow that the thinking is faster.
That doesn't follow because once you've mastered something you consider less options to reach a conclusion than a novice. One reaches the correct conclusion whit less thinking, not faster thinking.
Following your logic a person taking a shortcut from point A to point B is doing the same amount of driving as somebody not taking the shortcut, they are just driving faster.
