Introverts use more concrete language than extraverts

n = 40, this is junk. they couldn't even get 100 people for this?

these were all sampled from 1 company in amsterdam. the differences could be explained by company culture, or local culture, or whatever. more work needed.

n=40 isn’t actually bad for generalized conclusions, given a reasonable spread in the results. Your second point is a much stronger argument. The sample is entirely non-representative.
- IIRC from stats n=32 is generally considered the minimum to be considered representative for a random sample (and this is not a random sample outside of the company in Amsterdam 🙄).
That's very concrete language you're using there. Are you perchance an introvert? We could make it n = 41 and add a dash more selection bias to boot!
anything with personality types i already assume is junk. might as well use their zodiac sign.
Shitty sample sizes are the majority of "research" nowadays. It's sad how hard it is to find any even in the triple digits.

You can say that people who identify as introverts use more concrete language, but there's no reliable way to identify intro/extraversion because it's about as scientific as an internet personality quiz.

Jung's original definition that some people get energy from socializing while others have to expend energy to socialize doesn't hold up to scrutiny. We're social primates and sometimes we like socializing and other times we find it taxing but often it's a little of both.

If you really don't like socializing you may have some degree of social anxiety, and maybe you identify as an introvert. Which is fine of course - most people will understand what you mean.

But I think it's important to remember that we're not talking about a real thing that actually exists in our genes or brains. It's just a vague description of your attitude to socializing.

I can't say for sure whether or not this particular study used proper testing, but as a whole introversion and extroversion is not pseudoscientific.

Jung wasn't a good scientist, but he did a lot of studies and came up with a lot of theories, some of which happened to be at least partially correct. Also, you seem to be getting something mixed up because Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents", and extraversion as "an attitude-type characterised by concentration of interest on the external object", whereas the more common energy focused definition is not from Jung at all - at least, as far as I am aware.

The big five personality traits, namely openness, conscientiousness, extraversion, agreeableness, and neuroticism have been shown to be consistent, even cross culturally.

There are limitations to that: like how it's an empirical observation, that other personality traits exist that aren't factored into those five, or that it's possible there are a larger number of smaller subfactors that make up those five traits, but ultimately they are scientific.
In addition to Aezora's response, extrovert vs introvert being a description of your attitude to socializing is only a colloquial use of the term. I am a shy extrovert. I do not get social energy by being alone, like an introvert does, and I have problems talking with new people and even with friends prefer a back seat in the conversation.

Most people seem to fit into more clear buckets, if you believe the marketing, but that doesn't make the buckets the definition.

Clicked the link for the chart, couldn't see the chart without enabling JavaScript.

What the hell is with 'modern' websites? Of course, soon as the JS is lit up, it's pop-over reg/notifications/location crap obscuring the entire page.

You know, sometimes it could mean that the chart is interactive. But I don't think this one is lol

I get so much satisfaction whenever I see extravert spelled correctly, which is very rare these days.

First I wondered if the post had it spelled incorrectly.

Then you had me wondering if I've been spelling it incorrectly this whole time.

Turns out extravert and extrovert are both acceptable spellings but extravert did come first.
- Correct. But extrOvert makes no sense, etymologically (latin). The dictionaries accept it, but I (jokingly) don't.
I'm gonna start spelling it intravert.
"Correct" is in languages how the general population uses it.
- People seem to be downvoting you but you're absolutely right. Languages are dynamic and evolve all the time. The language "rules" are merely descriptive; they explain how most people use the language, and if you want to make sure everyone can understand you it's best to follow them.
  
  Even then there's some wiggle-room. Take the gif/jif pronunciation debate, it was coined as "jif" but the majority of people switched to "gif". So (depending on the dictionary you own) it will often either list just "gif" as correct, or list both as equally valid pronunciations (which given the sizeable minority for "jif" seems like the correct approach imo). All the gift/giraffe/creator-says-x is just fluff and not actually all that relevant.
Thank you! There are dozens of us who care. Dozens!

Yes? This wasn't known yet?

Tldr A British English, O American English
- A is also the way the inventor of the term spelled it, the way it is often spelled in science and the correct Latin form.
  
  I'm not saying O is wrong, that's what happens in language, just adding the other points.
- This is not to say that Jung wasn't a genius. Jung was THE BOMB DIGGIDITY (which, by the way, I wish was an official term in the Oxford dictionary).
  
  If they love Jung so much (which I agree they should because Jung was amaaaaazing), why don't they honor him by using the spelling he actually used?
  
  Love etymological articles with unreliable narrators.
- Tldr A British English, O American English
  
  What? How did you get to that conclusion? That's not what the article says at all? It says Phyllis Blanchard used the (then incorrect) spelling with an O (while also changing the definition of the term to something most people I think would disagree with) in a paper she wrote and nobody knows why. And it spread from there.
  
  I think you're interpreting "Today, ExtrOvert is the most common spelling of the term in the United States." to mean it's spelled with an A elsewhere, but the author even brings up the Oxford Dictionary (UK) that says that the original spelling with an A is rare in general use. I live outside the US and I pretty much exclusively see the O-spelling.
  
  EDIT: Changed from "incorrect" to "then incorrect" to clarify. She wrote her article before extrOvert entered the dictionary, and - according to the author of the article linked earlier in this thread - her article might have been a big contributing factor for it entering the dictionary that was published soon after.
The Queen has been informed of your transgression.

Please remain calm and do not attempt to flee.
- KEEP CALM AND REMAIN STILL
So confident, yet so wrong.
It's almost like language is inconsistent and evolving
Why not intravert? Could be fun!
no you misunderstand, these people are EXTRA verted, just SUPER verted to a degree it's hard to comprehend

This is accurate until proven otherwise.
