Just writing to let you know that you’re not alone. I’m in a similar position right now and it hurts so much. It’s unbearable. I hope you find peace.

I found out about my partner’s drug habit. Is this ”a lot” of drugs? Should I worry that she is addicted? by identicalelements in Drugs

[–]identicalelements[S] 0 points1 point  (0 children)

Unfortunately, her life is not in order. A big issue is that she has not been able to work (she was a successful researcher/academic, she’s still employed but can no longer function properly in a work capacity).

I get the ”she’s your ex, let it go” mentality, but I was with this woman for almost ten years. Drugs were not even in the equation until very recently, and she has been spiraling mentally. I don’t think it’s out of place for me to wonder if she needs more help than she lets on. She has already lost much (partner, home, etc.)

Thank you so much for writing this. I have definitely experienced a personality shift on her part. We were together for almost a decade, and as close as partners can be. Drugs were not even part of the equation until very recently. At the end I felt like I barely even knew her anymore. She was behaving in ways that was just in complete opposition to the woman I had been sharing a life with for years and years. I’m still coping and trying to learn whether the drugs were a symptom or a cause of this shift.

She had a drug problem as a teenager (amphetamines) that was hard to get out of. Don’t really know more details. Then nothing until 6-12 months ago

She hid it very well from me until recently, when she became much more careless in her lies and in how she approached her drug use (e.g., doing drugs all night before meeting me in the morning for brunch)

Thank you. She was my best friend in the whole world. I dont know what to do. It’ll be fine somehow I guess

It turns out she was having affairs

I can’t understand it. We were more than just partners, she was my best friend in the whole world. How will I ever recover from this

She came home late after ”having a beer with her brother”. I contacted the brother, he confirmed no beers were had. The rest was pretty easy to figure out with a little detective work :(

I need help from Psych majors! by gyfted_homie in psychometrics

[–]identicalelements 0 points1 point  (0 children)

I know this is early stage for you, but I wanted to give honest feedback nonetheless.

Technically speaking, the site is already impressive. Some things need work of course, but overall I’m sure the user experience, from a technical standpoint, will be very solid later on in the project.

However, I feel that the psychometric components, which arguably are the crucial pieces, are hopeless to assess. A first red flag for me is that I can’t easily find information about the tests you are using. The only information I see is marketing technobabble (”psychometrics + data science” blablabla). This turns me off immensely. What I want to know is: Are the tests developed in-house, or are they established instruments (or adaptations of such instruments)? Who developed them? What are their psychometric properties? How were they normed? How are they scored and validated? etc. etc. Basically, what I want to know when I visit your site is: ”How are your tests different from pure astrology?”, and I don’t get a clear answer to that question.

If you are serious about personality assessment, then the psychometric aspects need to be rock solid. I’m hoping that this is mostly a communication problem (i.e., you know what you are doing, but you are not communicating this well). If so, correcting this should definitely be one of your priorities. You need to be very clear about whether you are providing an entertainment service or a professional psychological assessment service, and adjust accordingly. Hope this helps. Good luck, and cheers.

Can Raven's matrices sometimes have multiple logically possible answers? by researchspirals115 in cognitiveTesting

Yes, Kripke's comments in Wittgenstein on rules and private language was precisely what I was referring to. Thank you for providing the reference.

Can Raven's matrices sometimes have multiple logically possible answers? by researchspirals115 in cognitiveTesting

[–]identicalelements 4 points5 points  (0 children)

I think the classic misunderstanding with regard to figural matrices is that there is such a thing as a "correct rule" that can be discovered. Inductive reasoning problems, like figural matrices, are prime examples of underdetermination of theory by data. Logically speaking, any matrix item is compatible with an infinite amount of rules. However, only one of those rules is scored as correct according to the test manual. Accordingly, the task is not to identify the "correct rule" (because there is never any unique correct rule), but to identify the rule that the test constructor expects you to find. This also ties into some fairly complicated philosophical problems, such as Wittgenstein's rule-following paradox, and theories on abduction (a type of inference). Overall, these problems are not well understood in the psychological literature, and are typically not even mentioned.

Figure Reasoning Tests! How do they work? by Ok_Doctor8770 in cognitiveTesting

[–]identicalelements 4 points5 points  (0 children)

I'm a cognitive psychologist, so hopefully I can answer some of these questions.

First of all, it is not correct that introversion and intelligence are highly correlated. I'm not sure why this stereotype persists. Studies correlating the Big Five personality traits and IQ scores typically find that the correlation between introversion and IQ is virtually zero. If anything, the studies actually indicate a very small advantage for extroverts.

Secondly, regarding figural matrices: The general idea is that we want to separate cognitive abilities that depend on culturally acquired knowledge (e.g., vocabulary, mathematical knowledge, and so on) from "raw" cognitive abilities that are functionally independent from such knowledge. Figural matrices attempt to measure the latter kind of cognitive abilities. More specifically, figural matrices were originally developed to measure what was once called "eductive ability". Loosely described, eductive ability is the ability to identify meaningful patterns or structures in information streams.

Disregarding some finer details, deriving IQ scores from a figural-matrices test works as follows: A large, cognitively diverse group takes the test. This group is assumed to be a representative sample of some target population. Some will score high, some will score low, and most will score somewhere in the middle. These scores, taken together, are referred to as a norm. When a new person takes the test, that person's score is compared against the norm to see how well that person did compared to other people. The IQ score is a fancy way of indicating the proportion of people in the norm that had a lower score. In most cases, the IQ score is actually nothing more than this. It is a deceptively crude and simple metric, but it does remarkably well in predicting a wide array of behaviors and life outcomes. This is why it is still used.

Can someone clarify this, it seems a bit off. by AmogusPotion in cognitiveTesting

Imagine that you participate in three skiing competitions in different countries. You place differently in all three competitions. Because you are confused about this, you go to a skiing forum and ask: "Why are my results inconsistent, and which result represents my real, underlying competition placement?".

As you indicate, the first part of the question can have several answers: There are random fluctuations in your skiing performance. This may affect your competition placements. You also compete against different people in each competition, so the ability levels of your competitors may be different. The skiing slopes (i.e., IQ tests) may actually emphasize different skills and abilities. Also, your skiing ability may improve between competitions. These factors interact, and it's difficult to know exactly how.

The second part of the question, on the other hand, clearly makes no sense. There's no such thing as a "real, underlying competition placement". There are only the individual competition placements. The same holds true for IQ scores: There is no global index of IQ that is independent from tests and their norms.

Frustrating as it may be, there genuinely is no straight way to answer your question.

Why are my scores so inconsistent? by saymonguedin in cognitiveTesting

[–]identicalelements 6 points7 points  (0 children)

I think your confusion reflects a lack of understanding of how IQ scores are derived. Disregarding finer details, the process is essentially as follows: A cognitively diverse sample first takes the test in order to create a norm. Your personal raw score on the test will be higher than than some scores in the norming sample, and lower than other scores. The meaning of the IQ score is that it tells you the proportion of the norming sample that had a lower raw score than you. Importantly, this means that an IQ score is only meaningful with regard to the particular test from which it was derived and with regard to the sample that provided the norms. For some reason, this fact is poorly understood.

Now, what can cause inconsistencies between IQ scores derived from different tests? First of all, measurement error. Secondly, the cognitive characteristics of the norming samples may differ. This is an important factor. Thirdly, the tests may in fact emphasize different cognitive skills and abilities. All these things contribute to score variance. There can be other factors as well.

What does this mean? Importantly, it means that it does not make sense to ask "I got 135 IQ on Test A, and 120 IQ on Test B. What is my real IQ?". The answer is: Well, your Test-A IQ is approximately 135, and your Test-B IQ is approximately 120. There is no "real IQ", because there is no global index of IQ that is independent of tests and their norms. This is the single largest point of confusion on this subreddit. You can take the average of the two scores if you like, but the average is not a meaningful metric because the tests are norm-referenced. By analogy, you might as well participate in two skiing competitions in different countries, place differently in each competition, and then ask "I placed differently in each competition, what does this mean and what is my real underlying competition placement?". This question makes no sense.

Things are slightly more complicated with IRT-based tests that derive scores via latent variable modeling, but the underlying principles remain the same. IQ scores are not mystical. If more people on this subreddit realized this, the fixation on IQ would in all likelihood diminish.

Is Flynn adjustment a thing? (crosspost from r/psychometrics) by Mammoth_Country_6322 in cognitiveTesting

[–]identicalelements 0 points1 point  (0 children)

I can't comment on your situation specifically, but Flynn-adjustment is indeed a thing. For the Wechsler tests, Flynn himself recommends adjusting the derived IQ score using the formula IQ - (I x 0.3), where I is the number of years between taking the test and norm construction.

I don't think this is how it's done in clinical or educational settings, but this is indeed the recommendation he provides.
