I think a lot of this analysis is tautological -- meaning that when you boil it down, you're just saying that things are as you have defined them to be.

For instance, take a Big Five trait such as agreeableness. How do we know that a person is agreeable? Because we define agreeableness in a certain way and then measure the degree to which someone conforms to the definition. If that measurement includes questions such as, "Do others find you easy to get along with?" then of course there's going to be a negative correlation with loneliness, because you've essentially defined it that way.

I am the author of Correlated.org, which commits many different types of statistical errors for humor's sake, so this leaps out at me. By the way, for a surprisingly vast number of things, agreeableness is quite predictive. Food preferences, public policy positions, and even willingness to answer poll questions :)

Articles like this answer the question, "what if 1920s eugenicists got hold of 1980s magazine relationship tests?"

The scary thing is a lot of commercial "people analytics" systems marketed to HR departments, lenders, and government agencies are little more than dressed up relationship tests from 1980s magazines.

Or Myers–Briggs, which is a lot older.

The main useful thing about this sort of thing, including the more modern Tilt 365 for example, is that it can be a useful exercise in helping people understand that the way they think about and approach the world differs from how others do.

Years ago, I remember a book (Tog on Interface) that had a chapter which discussed how Apple engineers tested on MBTI versus the general population. He went to discuss implications for how it was easier for engineers to have mental models for how systems operated than users. Was this a correct explanation based on MBTI? Who knows. But it was a useful reminder in this case that your users may not be like you.

I def found myres Briggs to be helpful, for your exact reasons. I know it gets a lot of hate here in HN, but as someone who was introduced to it in my first job right out of school, It made me more self aware of how I naturally process information and get energized, and how that can differ from others, and that bit of knowledge has absolutely helped me at times in my career. To me it was never sold as a “this is the only mold you fit in and it will define your role”, it was more to understand ways one might naturally process information, vs. ways one might need to actively work to process information differently.

I get the exact same response when I try to debunk horoscopes to someone who believes that’s just classic Virgo behaviour haha.

Controversial, but also true, is that I get the same response trying to debunk diversity hiring etc. because I happen to be a white, straight male. I am also practically blind in one eye and grew up poor, but I refuse to play the victimhood game or even agree to that frame to win an argument. Also I don’t want to get into the pros and cons of that topic in this thread as that’ll inevitably be a train wreck as always, but I just want to point out how frustrating it is to “lose” an argument because of who you are, not what you actually say. Also, for the diversity people, it’s super insulting to essentially suggest “you’re only disagreeing to protect your own race”. I honestly think the appropriate response is to tell them to fuck off after they bring up your race, gender, sexuality, etc. in an argument.

On the flip side of that, I typically don't add a disclaimer about my heritage or political leaning before going into similar discussions, and it is hilarious that people assume I am a cisgender white male in order to invalidate anything I say. I also find it completely appalling how the "allies" act like female, trans and people of color have no ability to think for themselves or have different goals and opinions. To me, this is just as hurtful if not more than the "silent" and overtly racist people. Of course, now just add "allies" to the people that will argue about their worldview being altered. In person, people look at me like I have grown two heads when I suggest a minority might have listened to divisive comments from the former head of state. As if that is the biggest absurdity. People don't even want answers.

Unless a HR department is doing something wrong, the test results aren’t the point of the tests. It’s the conversation following, where possible employees are confronted with their answers and results that’s the point.

It’s just easier to get there when you use a disguised relationship tests from 1980ies magazines. Not only does it touch on relevant areas, most people that you’d use the HR resources on secretly love taking those things and then talking about themselves.

As with most things, it can obviously go wrong or get used in the wrong situations. HR is a department that’s there to help managers, but they really shouldn’t waste their resources testing people for a position as a software developer. If your company is doing that, something went wrong. Maybe HR found a way to keep themselves busy, or you’re not bolstering a management culture or people who can make hiring related decisions without consulting HR.

Re:A review of correlations between big five personality typ... by moksly on Monday May 10, 2021 @04:28AM (#27103845)
Because you don’t really need the full personality profile show when you are interviewing people who aren’t going to be managers.

It’s not an insignificant amount of resources you put into the process. Not only do you take up HR resources, the team that is helping you recruit is also going to need to spend time going over the results with HR and the candidate.

In my optics that is an unnecessary waste of resources. Not only doesn’t the process really show you anything team-related, you should frankly be capable of judging people from the conversations you have with them just as well.

The in-depth personality stuff only gets relevant when the people you hire have to manage other people.

Re:A review of correlations between big five personality typ... by feanaro on Monday May 10, 2021 @02:14PM (#27109033)
It depends on what you mean by a "full personality profile". I think a skillfully chosen selection of tests, which may sometimes include personality tests, can aid in the selection of the proper candidate.

I agree that the battery of tests used should not be the same in every case. It should be tailored to the situation and to the position you are hiring for.

> Not only do you take up HR resources, the team that is helping you recruit is also going to need to spend time going over the results with HR and the candidate.

I have second-hand experience that this can be made very streamlined and does not take much time at all. Especially when you have a large number of prospective candidates and will not be able to see them all in person, a pre-filtering done by a skilled HR person is better than a random draw.

Re:A review of correlations between big five personality typ... by xwolfi on Sunday May 09, 2021 @07:42PM (#27100975)
Well because it's hard for them to come up with question and judge responses.

But I guess this means HR shouldnt skill-test anyone. We d all agree they shouldn't test a racecar driver, a CEO, a mathematician.

But the guy saying that probably doesnt work: HR never test anyone. They handle the process. He may be confusing it with wrong job posting that people attribute to HR (like N years xp in N-5 years old tech) which are usually the product of idiotic managers, not HR who doesnt give a fig what your team needs as long as you express it to them.

Maybe we have different ways of defining things, or maybe my English isn’t good enough to convey the meaning.

But isn’t HR handling the process of personality testing, HR testing people? When we utilise personality testing, a HR consultant actually tests the candidates. It’s their test, they spend millions developing it and you have to be certified to perform it.

Related to this, often I see a survey question along the lines of say, "which cup do you think would hold more water" with one that looks like it'd hold a lot more than the other. I'm never sure whether to answer with the meta-analysis of the fact that it's a survey question included in my answer.

That is, if I saw the two cups in my example naturally I'd say the obvious one holds more water, but often there'd be no point in putting it as a survey question if the obvious answer was the case. Therefore I'm almost sure the correct answer is the seemingly wrong one.

So I put that as the answer and get it right. But for whoever's running the survey, I'm probably messing up their results by meta-analysing the questions.

I think it’s perfectly ethical to game the tests, but it can be hard to tell what’s actually being tested.

One or ours was deliberately set up so that prospect hires applying for a leadership position would end up with very, very, little in their empathy score if they chose answers that sound like the “right” ones for a leadership position. It was done to catch people off guard in their next interview, and see how they handled getting shown a result they’d very likely not agree with.

HR departments know these things are bullshit. They know people game the systems, exactly like people practice for the coding interview. The test and the results are often extremely irrelevant to anyone getting hired, it’s how people handle their results that’s important.

If you wan my personal opinion I think HR exists solely to come up with reasons for HR to exist. Well minus the administrative part of handling employees payments (including stuff like maternity/sick leave) and the lawyers. But both of those functions could be branched into economy and general legal.

The entire branch of team-building/personality matching/management consulting/management training/management network facilitating is a fat unnecessary cow that enterprise organisations will never get rid of because they are very good at being “people skills” and positioning themselves with top management.

After a year of lockdowns, where they’ve been completely unable to execute their regular function, their absence have left no mark on our organisation though.

Re:A review of correlations between big five personality typ... by anbende on Sunday May 09, 2021 @02:55PM (#27098629)
While this is true for a lot of common psychological constructs, the Big Five were not defined according to agreement or consensus. The definitions were driven by the lexical hypothesis whereby the wide variety of personality descriptive adjectives in human language were factor analyzed and found to cluster into 5 distinct factors.

So this isn't tautological in the way that you've described, though it is certainly related to the way human beings describe each other and the way that instantiates in human language.

Humorism was a field of academic study for two millennia before germ theory demonstrated how laughable the entire field was. It’s always important to remember that doing research in a field doesn’t necessarily mean that the field itself is on a solid foundation that maps to reality. Psychology and psychiatry really do struggle to demonstrate statistically meaningful results behind most therapies (CBT is perhaps a notable exception, although even there results can be mixed). Analyses like the big 5 are squarely in the “let me read your tea leaves” camp of “science” IMO. They basically play a trick of “sure, the other personality theories were bogus but this time we did stumble upon a good way of characterizing it” while taking at face value that the entire endeavor as valid. Neuroscience has a bit more behind it because it’s actually rooted in quantifiable measurements somewhat and even there it’s difficult. It’s like trying to reverse-engineer a modern CPU from X-ray lithography. If you know the theory underpinning everything, you can start to make educated guesses. Without that you’re not going to get anywhere close to what’s going on let alone root cause if something is broken.
Re:A review of correlations between big five personality typ... by anbende on Sunday May 09, 2021 @03:32PM (#27098968)
A major problem with humorism was that it did not have any empirical evidence to support it.

Modern personality theory DOES. Personality theory uses a variety of techniques to show that a construct is internally consistent and related to real-world indicators. If independent people can view a video or a person and they reliably rate that entity similarly (inter-rater reliability), we can say with some certainty that there is something there. Relating a construct like this to a variety of real-world outcomes allows us to ascertain its relationship to the world. This evidence is messy and not nearly as solid as what's found in the harder sciences, but your dismissal of the modern statistics of questionnaire-based measurement does a very well-researched field of inquiry a huge disservice.

Re:A review of correlations between big five personality typ... by vlovich123 on Sunday May 09, 2021 @03:48PM (#27099099)
My analogy to humorism was not to imply that there’s no empirical evidence at all here. Just that the field of psychology has continually struggled to actually develop testable hypotheses that lead to scientific theories.

There’s a giant chasm between “I have a signal” and “here’s what that signal means”. You can’t start out with a data set, pick out some signals and then say what they mean. That’s scientific theory 101. You build a hypothetical model and then design experiments to test those theories. It’s not me doing the field a disservice. The practitioners have consistently and repeatedly done bad science and statistics. I’ll be more supportive once the field actually starts producing falsifiable theories that are supported by evidence and the practitioners are better at calling out their peers.

You seem to be conflating psychology the science vs psychotherapy the practice.

Just like with medicine, you don't categorically reject medications even though it can't always explain the mechanisms of action fully (yet).

I've seen how large companies make ≈$X0 million decisions and probably $X00 million decisions and I suspect $ billion decisions aren't treated fundamentally differently. I wouldn't use that as evidence for how to make decisions well.

My current theory is that companies are successful not because they consistently make specific tactical or even strategic decisions well but because (through design or evolution) they are resilient systems that can weather surprisingly poor decision making at all levels.

> Neuroscience has a bit more behind it because it’s actually rooted in quantifiable measurements somewhat and even there it’s difficult.

The problem still remains of how the physical measurements (even assuming we could measure them perfectly, which we definitely can't) relate to the internal experience.

Any real theory of psychology/neuroscience needs to be able to explain that, and currently I'm not aware of any that do.

> Psychology and psychiatry really do struggle to demonstrate statistically meaningful results behind most therapies (CBT is perhaps a notable exception, although even there results can be mixed)

So it's incredibly difficult to do good studies of therapy, because there is no simple placebo. All of the research I've seen suggests that there's huge amount of provider-level variance, which swamps the theoretically meaningful defences. I would suggest that this is because we don't really have a good understanding of how to interrogate our own (or others) psyches, which is definitely not something that neuroscience will help with (given the current state of the field, at least).

To be fair, Costa and McCrae did a lot of great work on the Big 5, but they really didn't like it when SEM/CFA didn't really support their theory.

In fact, they liked it so little that they invented Procrustean rotation so that they could make the factors come out the "correct" way.

Once I discovered that, I paid a lot less attention to the Big 5.

Also, I haven't checked the source papers, but that all blue stuff could come from a general tendency to agree with the questions/put a positive spin on that. I do know that not all personality measures are balanced on positive vs negative questions, to remove this bias (life satisfaction methods are almost certainly not balanced in this way).

Re:A review of correlations between big five personality typ... by jawns on Sunday May 09, 2021 @03:03PM (#27098690)
But isn't that just tautology with an intermediate step?

You might have Personality Descriptive Adjective X that is found to cluster into what we call a Big Five trait.

But Adjective X has its own definition, and it's likely that the tautology (at least insofar as these life satisfaction correlations are concerned) happens at that level.

Re:A review of correlations between big five personality typ... by anbende on Sunday May 09, 2021 @03:23PM (#27098890)
Tautology implies that the definition we give is redundant, but none of these things were defined in this way. This is because none of the research relies on this kind of dictionary definition.

Instead, they literally ask people hundreds of questions of the type:

"To what extent would you consider yourself to be [adjective]?" (0 - 'not at all' to 5 - 'complete')

Then they factor analyze the results to see which adjectives tend to be highly related to each other. Factor analysis builds on correlation to find shared variation among large groups of indicator variables.

So it is related to how people think of the adjectives and what they mean, but it is not the case that we are just lumping definitions together or "saying the same thing in different words" in the way of a tautology. Instead, what we're saying is that "Most of these personality adjectives mostly mean the same thing. Here's the thing they all mostly mean. If humans in all languages have tons of words that mostly mean this common thing, maybe this common thing is significant and worthy of study."

Regarding life satisfaction, the sense that one finds their life satisfactory and "would change nothing" (one of the items in the Satisfaction with Life Scale that was most likely used to measure it) doesn't show up in those other traits in any major way. In fact, to the extent that a description of the self is related to a world-view, belief or other external factor, it will never be a tautology, because a self-view and other-view or world-view will never share a common definition or tautology by virtue of the self-other distinction.

The big problem with these results (and god knows I've analysed enough of them) is that the extent that they map to other characteristics measured without surveys is pretty much unknown.

If you want to create a new measure of extraversion, then you use the older methods (i.e. other surveys), and this only really tells you that the new measure correlates with the old.

I vaguely recall Eysenck doing physiological tests for extraversion/introversion which would avoid this problem, but I'm not aware of any more recent research in this area (mind you, I've been out of the field for a decade now).

I suppose they asked 1000s of different questions, each representing a different personality characteristic. After factor analysis, some arbitrary number of factors were found to account for most of the variance. Why did they settle for 5 vs 8 vs 12?
Re:A review of correlations between big five personality typ... by anbende on Sunday May 09, 2021 @03:54PM (#27099153)
There are a number of metrics that are commonly used to settle on a number of factors to extract. There's some judgment in it to be sure, but you are looking at data-driven phenomena as well like percentage of variance explained, a precipitous drop in new added value, and etc.

Essentially you come to a point where extracting another value isn't explaining much more variance or producing a factor that's meaningful (e.g., two items of conscientiousness with negative wording are the entire new "factor" and only take variance explained from 80% to 82%).

Like pretty much every unsupervised learning problem, there is no data which can tell you what N should be. If there was, you could trivially use that measure to convert it to a supervised learning problem.

More generally, all of those metrics are pretty fluffy (the scree plot is probably the best, as it doesn't give you a p-value).

In order to actually do this right, you need multiple studies and CFA, but the standard in the field is to refit your exploratory model as a CFA on the original dataset, which is almost certainly causing overfitting in most cases.

Other models actually did settle for higher numbers of factors, but higher numbers were usually found to have categories that could be reasonably collapsed into one of the Big 5.

Fwiw, my understanding is that most psychologists believe that with further study, these categories will map to actual functioning of the brain and nerve systems. For example, "Neuroticism" will somehow map to the excitability of certain nerve systems and "Agreeableness" will somehow map to functioning of our mirror and mentalizing systems. "Conscientiousness" will map to inhibiting functions, "Openness" will map to approach/flee type emotional functions, and "Extraversion" will map to systems like dopamine release on securing rewards for behavior.

So how do we objectively measure all 5 dimensions? I.e. would I roughly assess myself similar to how others (on average) would assess me?

Given that the definitions of words and phrases are possibly subjective, I've often wondered if the personality test largely measures how people interpret the questions.
Re:A review of correlations between big five personality typ... by tikhonj on Sunday May 09, 2021 @02:53PM (#27098605)
My understanding is that the point of the Big Five model is that the design was the other way around—we started by looking at how answers to personality-related questions naturally clustered, then we gave names to those clusters. We define "agreeableness" because a particular set of answers/preferences/etc were correlated and could be interpreted as "agreeableness".

Of course, there are limitations to this kind of approach and there's been a lot of research and refining done on top of this—not being an expert, I'm not familiar with it—but the core of the Big Five model is observational, not tautological.

Re:A review of correlations between big five personality typ... by HPsquared on Sunday May 09, 2021 @02:17PM (#27098276)
My (lay) understanding is that personality data tend to be clustered such that it's best explained by five factors, with the names of the factors (Openness, Conscientiousness, etc.) having been added later.

Wikipedia states it pretty well, "When factor analysis (a statistical technique) is applied to personality survey data, it reveals semantic associations: some words used to describe aspects of personality are often applied to the same person." [1]

The Big Five are a statistically-derived groupings of phrases that are reasonably stable when measured from different angles. I think it would be fair to call it a "modest initial result" if compared to the physical sciences, or "wildly successful" if compared to basically anything prior that came out of the social sciences. There are some quite reasonable critiques listed on the wikipedia page, such as a lack of modeling theory, or only accounting for a portion of personality differences, or arguments for a slightly different number of factors, etc. That said, it seems to be one of the first actually solid findings that ever came out of the social sciences. It's like the whole field has been flailing around, swept down a river in the dark, and for the first time we found a stone that has a bit of purchase, even if it's covered with moss and slippery.

Wildly successful is a term that would be better applied to item response theory models, the Big 5 (and personality psychology more generally) are at the leeches stage compared to them.

That being said, it's much much harder to develop measures when you rely on other measures of the same type to validate them, which is where personality testing is right now.

Re:A review of correlations between big five personality typ... by infogulch on Monday May 10, 2021 @11:52AM (#27107400)
By response theory do you mean behavior research by Skinner, Panksepp, etc? Yes, basically everything in personality psychology barely even registers compared to that, I agree that my comparison was too broad. A more reasonable statement might have been that Big 5 is wildly successful compared to other personality models.

Thank you for the correction.

Nope, I meant item response theory: https://en.wikipedia.org/wiki/Item_response_theory

It's a much, much better method for designing and analysing questionnaires, and it is the foundation for all standardised testing (SAT, MCAT etc).

Sure, there are some that seem roughly tautological (like "Popularity" and "Extraversion") but who cares – there's a bunch here that's interesting.

For example, that conscientiousness (aka diligence/organization) correlates more positively than extraversion with Job Income but less positively with Life Satisfaction and negatively with Popularity.

Agreeableness having a light negative correlation with Income and Intelligence is also thought-provoking and not at all tautological.

Hum i did not know that word but i have thought allot about that.

Especially in relation to “neurological disorders” like ADHD. Where some people blame their ADHD for their behavior. Or basically anything that has to do with personality. It is clearly as you say tautological. You have a certain personality because you behave in a certain way, you don’t behave in a certain way cause you have a certain personality.

But then you have the fact that earlier personality can be used to predict future personality and future behavior. It is not causal but it is predictive.

Some people call that causal people in social science. I think that is twisting the definition of “causal”.

Or free will, if you believe or don’t believe in free will is a tautological consequence of how you define the self.

Some people define the self in such a way that free will can’t exist and others define the self in a way so that free will must exist ie. It could not possibly not exist.

> If that measurement includes questions such as, "Do others find you easy to get along with?" then of course there's going to be a negative correlation with loneliness, because you've essentially defined it that way.

Lack of agreeableness may drive others away, but if disageeable people also want less socialization, they might not be more lonely than agreeable people.

I personal think I'm pretty agreeable, but it would take a lot for me to feel lonely, so even if I were very disagreeable, I imagine I'd still have enough people around to suit me.

Re:A review of correlations between big five personality typ... by eCa on Sunday May 09, 2021 @05:26PM (#27099951)
Quite a leap from ”I’m agreeable but prefers to be alone” to ”disagreeable people prefers to be more alone than agreeable people”.

I'm often skeptical about those things, because they try to measure, but those measure are based on a definition of vocabulary, which is difficult to define.

Personality is vague. It's pretty common knowledge that the brain is a complex machine and it's quite difficult to distillate some sort of evaluation, metric or measure for something that obviously has a million or billions ways to be measured.

It's already hard or difficult to treat psychiatric illness, so evaluating personality seems like an odd quest.

>For instance, take a Big Five trait such as agreeableness. How do we know that a person is agreeable? Because we define agreeableness in a certain way and then measure the degree to which someone conforms to the definition.

I'm not sure what's the point of this observation.

This is the case with every term.

How do we know someone is a murderer, a cry-baby, a thief, a chef, or any trait X?

Because "we define X in a certain way and then measure the degree to which someone conforms to the definition"
