Ask HN: Are people only smart until they talk about things you know more about?

52 points by theyx ↗ HN
Hey, all.

Have you ever noticed people who you regarded as smart/intelligent, show themselves not to be that smart when they talk about something you know a lot about?

Say, you come to Hackernews/Reddit and usually see people on these sites as knowledgeable people. But when they talk about a topic you know very well, you realize they aren't that smart.

And, if this happens to the topics you know a lot about, what about the other topics you don't know much about? Are they wrong about those too?

So my question is: is there a name for this "effect", that you "lose trust" on someone you regarded as knowledgeable when they talked about something you know well?

The Gell-Mann-Amnesia effect probably comes the closest to what you are looking for. It doesn't refer to the loss of trust but rather to the effect that we tend to forget that a source is not trustworthy. In the words of Michael Crichton:

> “Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them. In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.” (https://en.wikipedia.org/wiki/Michael_Crichton#Speeches)

That’s exactly this!!! Thank you very much.

To what extent you think this should affect our trust on news sources/websites like Hackernews?

Only to the extent you can verify. Although that highly depends on your ability to control/counter your own bias.

Safer and easier way: don't trust anything.

Opinions are like arse holes, we've all got one, and few smell pleasant.

When you see this situation, ask yourself "why is this person wrong? why are they so confident in their opinion?" Often its because we think we know more than we actually do, we believed the things we read without bothering to give them the basic smell test for rationality. Where someone involved in the area has had exposure to the basic realities the readable sources do no or cannot impart.

Computer folks are especially subject to this error, I think, because all of our work is essentially readable, all the knowledge is communicable via text, and almost all the "rules" were created by human design that intended rational ends, even when it missed.

Carpenters by contrast get early and unavoidable lessons in the perversity and stubbornness of the real world, the effects of entrapped tradition, and the occasional need for black magic and blood sacrifice to get the job done.

This doesn't make them any less predisposed to error than the computer scientist in areas outside their competence, but it informs the shape of the errors they make.

After having been fairly close to a story that made national news some years back, and more recently been involved with an organization that gets/got a fair bit of local media coverage, I think I have a pretty good yardstick for accuracy or the lack thereof. The existence of some astonishingly bad journalism does not preclude the existence of the remarkably good; I can't damn them all, but I can say they're all worthless until I give myself a reason to trust them.

Before even trying to assess the accuracy of a story, I have to take a step back and assess the competence of the source. Read some other stuff they've written. Is any of it on matters I'm well-acquainted with? Do they seem fuzzy on basic facts, or have clear and cogent explanations? Does any of it open my eyes to new perspectives even on things I thought I knew? Is the new story in a field they seem to have competence in?

Then, I look at the facts presented in the story in question. Assume I don't have my own sources for the facts, but I can look at how they're presented: Are they clearly explained and sourced? Do they have the logic wrapped in a lot of inverting layers (judge blocks appeal of injunction against measure that would've prohibited another activity, wait what? is that a green light or a red for the activity?) which they successfully unwrap for the reader, or are we left to fend for ourselves? Can I take some of the named sources and go look at their own writings and see if they're being quoted accurately?

Then I look at the emotional language surrounding the factual statements. Do they seem to have a horse in this race and incentive to push one side, or is their opinion merely a product of being informed about it? (I'm willing to accept that researching a story naturally produces an emotional narrative, and conveying that can be an important part of context, but the facts should shape the narrative, not the other way around.) Is there enough information that I can imagine the other perspectives that might surround these facts? Do I want to go dig some up?

I don't think being smart has anything to do with this. You may want to replace "smart" with "knowledgeable about a topic I'm interested in".
Yeah, there is a very big difference between having a strong grasp of a particular domain of knowledge and being generally intelligent: that is, able to reason and make logical inferences in the absence of knowledge.
> Say, you come to Hackernews/Reddit and usually see people on these sites as knowledgeable people.

This may be part of the rub: there are a bunch of bullshitters on the internet.

I don't think it's a problem we can blame on technology.
“ An expert is somebody who is more than 50 miles from home, has no responsibility for implementing the advice he gives, and shows slides.” -Edwin Meese
Every time I see news coverage of technical areas in which I have expertise, and they get something glaringly wrong, I wonder for a moment how much other stuff they're getting wrong when I don't notice because it's outside of my specialization. Frankly terrifying, since the news shapes opinions for most people.

Indeed. In my experience, the bad feeling gets even worse when noticing something wrong in something you are not specialised at all.

However to your point, Michael Crichton describes the rather sad "Gell-Mann amnesia effect": One tends to still trust the other pages of the magazine.

Hopefully people don’t use TV news or newspapers as their only sources of information. Newspapers are good for getting a feeling for what’s currently going around in the world – but one also need to complement them with other publications. E.g. books, meta-studies, etc.

Let’s take an example: If I want to know what’s going on in Yemen this week, I’m probably better of reading The Economist than borrowing a book at the library. But if I want to get a deeper understanding on the situation in Yemen, I’m probably better off reading a book rather than a news article.

Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray [Gell-Mann]’s case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the “wet streets cause rain” stories. Paper’s full of them.

In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.

In my case, it just reaffirms the notion that being a smart fool is not really an oxymoron, and that people at large are fools, myself included.

We all sometimes have a tendency to talk about the things we know jack about while posing as experts because we read an article in the Guardian about it once, or an abstract from a paper. Some more than others.

In the world of show business and television, I’ve seen celebrities — singers, stand up comedians, those kinds of people — often being asked about their stance on complicated political issues or life advice as such — and they spoke bullshit with a mild air of authority instead of running away, which a sensible person should have done. The thing, though, is, that the fact they are celebrities means there are crowds of fans who will listen to whatever they say as if it was God’s own truth.

Hey, you can treat what I just wrote as uninformed bullshit, likely you even have reasons to, like data to contradict my statements. It’s ok. I’m likely a fool.

> and they spoke bullshit with a mild air of authority instead of running away, which a sensible person should have done.

I think often they're asked because they've expressed interest in a topic or cause, and they realize that any benefit their name and the exposure they have at the moment is wasted if they ignore questions about it.

That they misstep is probably no different than any fledgling PR person the first day on the job, and sometimes I don't doubt it's media baiting them with questions to expose their lack of knowledge of some areas of the topic, as it makes for good coverage.

A lot of the times I give celebrities a lot of leeway in their knowledge, because most the time it's obvious that they just want to help because they feel fortunate for their current situation and want to give back. Sometimes that seems to be misapplied because of their lack of deep understanding on the topic, but at least their hearts seem to be in a good place.

I’ve been thinking about those concrete examples I remember which have driven me to the conclusion I stand by now, and it was always more like “what’s your take on this thing that’s resonating in the news/happening where you live”, and they feel compelled to have an opinion and sound smart and deep on top.

It’s likely worse with celebrities who are generally smart and well-read on a wide range of subjects, who think that because they think they know a thing or two, that they should bestow their pearls of knowledge upon their audience.

The reality, though, is that they are in fact an illustration of the popular understanding of the Dunning-Kruger effect, because they don’t know how much they don’t know, sometimes even after a demonstration of the contrary.

I know about at least one such person who gave very thoughtful interviews on politics and blogged opinions and how he knew how to put things right, ran for a seat in the parliament twice, actually got elected both times, and failed miserably at his job both times, ending his mandate prematurely.

Well, I'm not going to act like some people don't interpret their success as a mandate of how exceptional they are overall, and I'm sure being somewhat more intelligent than average in an industry known for sycophants probably leads to some unhealthy mental self image problems. These people definitely seem to exist. I think we should be careful to not let our admiration and displeasure of each set color our interpretations of the other though, and keep in mind some people are just trying to help where they can.

> the popular understanding of the Dunning-Kruger effect

You had me (my upvote) at hello (the acknowledgement of the popular misunderstanding). ;)

I see the same in the news a lot. When you are deep in an industry you see all the important errors they make reporting on what happened often missing the point entirely while making something else up. At any reasonable niche the amount of people who likely can have a quality opinion on something is really quite small and that includes alas the journalists who didn't grasp the details when they interviewed the experts.

We are all fools on many topics, most topics. One of my mentors in the past used to say there was no substitute for experience in an area. If you were joining a project and the members had a head start you should listen and learn because their experience was way ahead of your opinions on how it could be done.

I develop doubts when it comes to journalism, especially when it is presented from a point of authority and sold as truth. I don't with individuals, because all of us a prone to use expertise in field A to judge field B. Doing so constantly, and ignoring people knowing more than you is what makes you a fool.
Should this affect our trust in news sources/online media (blogs, op-eds, articles)? If so, where do we draw the line between content worth reading and meaningless opinions?
> We all sometimes have a tendency to talk about the things we know jack about

Why not participate in the norm of stating the source of your claims. It's easy enough to start a sentence with "I read in the Guardian" or "If I remember correctly" or "I heard from a professor once".

It even helps just to share your credence in your claim, e.g. "I suspect this is true", or "I'm pretty sure this is how something works".

> But when they talk about a topic you know very well, you realize they aren't that smart.

In the historical academic and intellectual epicenter of the US (East Coast college towns), the rule about not talking about a subject in which you are not an expert is still somewhat followed.

It is completely shattered in SV and coastal cities + DC

Case in point:

"Zero cases by the end of April, bruh...you gotta stop panicking bruh!" [0] AKA, the reason why Boston can't stand Elon Musk.

[0] https://twitter.com/elonmusk/status/1240754657263144960?lang...

Interesting distinction between east and west coast! Could it be because academic fields are less influenced by “looks and impressions”, while SV/technology fields are easily manipulated by people who appear to be experts?

As in: in academia if you say something, people are trained to analyze the veracity of that, and to judge you based on your methodological/academic rigor. Meanwhile, in SV people judge you on past projects and financial conditions, which are not tied to knowledge about reality at all. I don’t know if any of what I am saying is factually correct, I’m just guessing and wondering. Don’t take it as fact, just my biased, un-founded opinion created around what I see online.

I think it's because those who have knowledge of financial and human capital are the ones who make the final sprint of the marathon of problem solving.

When the science is knocking on heavens door after years or decades of struggles they feel the opportunity of commercial success and come out of the woodwork to make the last effort to finally push the pile over the goal line by making adjustments in how human capital and financial capital are deployed.

There's a big difference between being smart and being knowledgeable. Smart is the ability to process information and make deductions. Knowledge is information itself.

Or, to put it the other way, stupidity and ignorance are two separate things. All of us are ignorant of more things than we're knowledgeable about -- even the geniuses among us.

Get a really smart person to talk about something that they have little special knowledge about, and they aren't going to seem any smarter about it than most other people.

You should look up Gell-Mann amnesia. The basic premise IIRC is that the media's credibility is undeserved. You go through a newspaper reading about this and that, nodding along. When you happen upon an article in a field you know a lot about you realise how clueless the reporters writing the article are. You turn the page, get to the next article and forget all about reporters's cluelessness or the fact that it might extend to other fields you do not know that much about.
I was going to ask if anyone remembered the name of this, but you gave it to us. Thanks.
Bounded Rationality. We have 6 inch chimp brains and the universe that needs to fit in it is slightly larger.
Genuinely smart people are the ones who ask lots of questions when talking about an unfamiliar topic.
No quite the reverse. The people I work with and befriend are always very good in what I specialize in.

It’s when it comes to other topics that we wildly diverge in conclusions.

I think you misunderstand what "smart" means. More likely what you think by "smart" is actually "smart, knowledgeable and wise".

Smart is only capacity for noticing and understanding new things. It does not mean the person has presently a lot of understanding of things (knowledge) or that it has good judgment to not say untrue things in area they have no idea about (wisdom).

A person that is smart but has little knowledge will not be able to keep up in discussion with you in your area of expertise even if they are actually more intelligent than you.

Give them some time and see if they can pick up things fast or are slow to understand new concepts. This is better way to judge if somebody is or is not smart.

**

Imagine following situation: you are talking about something you know a lot about with a person that has no knowledge in your field of expertise.

That person decides to learn your field.

Let's say, in 2 years they know more in your field than you will ever know and they even are able to get a lot of original insight that leads to some astounding accomplishments.

Ask yourself, was that person "not smart" when you first talked to him/her? Or maybe they were always smart but they still needed to invest at least some time and effort to learn the field?

I always saw intelligence as a willingness to acknowledge what you don't know and withdrawing from comment or discussion about things you don't understand well enough to have an informed opinion on.

Unfortunately, this kind of humility/modesty is not rewarded. As we see in the world around us.

I think you're using the word "intelligence" to mean "respectable" or something else that isn't intelligence at all. Perhaps similar to how people use "stupid" to mean something that hurts them - "The stupid fly won't let me kill it!".
I generally found that smart people keep calm and it is discovered slowly, with more and more interaction. People who showed off and bragged a lot were generally found to be shallow in my experience
Not exactly what you are looking for but a related quote by Charles Bukowski: "The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence".

Often, on HN and Reddit, the most confident or authoritative sounding statements are also the most wrong. It always baffles me just how confident people can be in themselves when they really have no good basis for that confidence.

I think part of the problem is that we collectively tend to reward the "confident sounding" comments because we wrongly assume that only an actually knowledgeable person would have authored them.

You are right. We run the risk of building a society (or at least an online environment) built upon the confidence/mistakes of the loud fools.
Isn't it a paraphrase of Bertrand Russell?

"The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt" — from The Triumph of Stupidity, 1933.

1. Confidence can take you far

2. People usually have a lot of shallow knowledge on many things but deep knowledge on very few (if at all)

3. Many things are complicated enough that shallow knowledge==wrong knowledge from an expect point of view (the same way high school physics usually don't have friction, you sacrifice correctness for simplicity)

That's being informed. Smart is being able to learn new things quickly, make the right conclusions and other things independent of any specific domain.
Our modern economy pushes people to appear as "experts" for the purpose of their career, personal brand, and earnings. If someone poses as smart/an expert/well-crafted or well-filtered it's because they are playing the career game, or they look at others playing the career game around them and guess that they are supposed to act like that. Real intelligence is playful, open, curious and comes across as ridiculous most of the time.
What you're talking about is very closely related to the Gell-Mann Amnesia effect.

Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them. In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.

That depends on what you define as smart. I see that someone being intelligent goes beyond knowledge and rhetoric. So, I tend to believe that you can only 'truly' judge how smart someone is by being together involved in a topic that you two are not experts on. And this goes beyond pure logical reason, but also how it can connect things to reality and generate useful insights.
