There is clearly a major problem with this in SV. A lot of people seem to confuse confidence with expertise, and fail to grasp that a scary proportion of the time the individual is so confident because they don’t understand the problems with what they are doing. Furthermore, modern software management practice doesn’t want this because it wants replaceable cogs. If you can recognize expertise you have to appreciate t…

// Customers tends not to be experts. So after a certain level of skill has been achieved, any improvements that are made through experience are invisible to the people you’re selling to.

The relevant question is - does it matter? The Formula 1 pit crew is more expert than the mechanics at the Toyota dealership in ways I can't appreciate - but does it matter for my Highlander's oil change?

The answer might be "Yes, the F1 crew will do it in a way that prolongs the life of your engine" (I care about that!) or "Yes, the F1 crew will change your oil in 20% of the time" (I may or may not care about saving a few minutes every 6 months) or "No, you won't notice a difference but they are just more expert" (in which case I totally don't care!)

Part of expertise is ability to articulate its relevance to a given situation. Your customer may need help in validating your expertise, but at least start with the claim of what you can do.

// So why would you need to pass on your genes to study evolution? You can study whatever you want, I am questioning if you can be considered "expert" if you profoundly fail at the topic of your field.

> I am questioning if you can be considered "expert" if you profoundly fail at the topic of your field. You are confusing the person with the field of study. This confusion is more obvious if you think about the superconductor/ expert on superconduction example. A superconductor is a material which conducts direct current with near zero resistance. You can test if something is a superconductor by aligator clipping a…

Okay yes, but I measured a supposed superconductive expert and they weren’t superconductive even at lower temperatures. What would you say to that?

Author here. Previous time this was on the front page: https://news.ycombinator.com/item?id=30930985 As an update, I temporarily relocated to a different city and spent four months training Judo for five hours every day and have since reached the vocab point for the sport. That experiment was covered here: https://commoncog.com/expertise-acceleration-experiment-judo... and https://commoncog.com/mental-strength-judo-l…

Loved the post. Just to add to the principal observation about the vocab point — One thing I’ve noticed is that experts who can communicate/teach well are very effective at getting you to the vocab point (to the extent possible without experience) quickly! And once you reach the vocab point, the field is legible enough that you have the means to organize deliberate practice and interpret experience (if you want to go towards mastery) or delegate details (if you don’t need them). I wonder if this provokes any more thoughts from you.

I see zero problem with having no children and studying evolution. You don’t need to become superconductive to study the physics of superconductivity. You don’t need to become infected by every virus to study virology, and you definietly don’t need to be a virus to be a good virologist. So why would you need to pass on your genes to study evolution?

// So why would you need to pass on your genes to study evolution? You can study whatever you want, I am questioning if you can be considered "expert" if you profoundly fail at the topic of your field.

Your examples don’t show people failing, they show you don’t understand their fields enough to know what success means.

F1 pit crew members are highly trained athletes who specialize in fast tire changes. Many of them are recruited from other sports based on strength, speed, and agility. They often have no real experience as automotive technicians.

F1 teams do have world class mechanics but most of them aren't part of the pit crews.

Are you familiar with the expression missing the forest for the trees?

I'm glad you were able to articulate this idea so clearly. I think similar advice which maybe isn't so clear is to try to avoid "being the smartest person in the room".

On the topic, I'm reminded of coworkers talking about the most recent Super Bowl (I think, I don't follow sports) which included commentary from players who played as quarterbacks in the same season. One of the things my coworkers mentioned was how interesting it was to hear them talk about the game because they used unfamiliar terms.

Wouldn't it be better to hire a mixture of specialists and generalists especially today when diversity should be focused in thought rather than looks. Someone not me said that specialists are a master of one and connector of none.

Sure, ideally. In the real world hiring managers have to take what they can get from the applications that come in. And in a rapidly changing industry the specialists that you need today might be useless in two years. One approach that can work in some organizations is to hire mostly generalists as employees, and bring in specialists when needed as temporary contractors.

Not directly related to the article but I had two amusing encounters with expertise recently. I sat next to an Econ professor (at an Ivy) on a flight. I told him I had worked at a hedge fund, and he was like "wow, I could never put myself in a situation where my living depended on my economic theories being right." A good friend of mine is a kinda-famous evolutionary biologist. He's in his mid-40s now, unmarried and…

I actually would hesitate to take a course from an economist who doesn't have a track record of making accurate predictions in the real world (not necessarily about trading specifically). Most of econ has always been unscientific bunk that isn't even useful for practical modeling. Why waste any time learning it unless you need the course to meet arbitrary graduation requirements or something?
