      This cracks me up because it is often said with such confidence, but it is just wrong.

      If you have 10 people, 8 have an intelligence score of 1, 1 has a score of 5 and 1 has a score of 10. The average is 2.3 which means that 80% of the people are below average.

      The median is the only thing that is going to guarantee 50%.

        On a bell curve the average and mean are the same. Your example isn’t a bell curve. Many things will be a bell curve.

            No. It’s not.

            a single value (such as a mean, mode, or median) that summarizes or represents the general significance of a set of unequal values

            Source

            Depending on the context, the most representative statistic to be taken as the average might be another measure of central tendency, such as the mid-range, median, or mode.

                I think a lot of the time people see stupidity in differences of values and limited visibility of the context the decision was made. I think this is why so many people think so many people are stupid. ‘Stupid people’ make choices that the observer sees as having ‘poor results’.

                Like when a lane ends on the highway:

                – People are stupid (and selfish) for not letting cars in when their lane ends (dangerous)

                –People are stupid (and selfish) for waiting until the last minute to move over (dangerous)

                – People are stupid for moving over well before their lane ends (missed opportunity to get ahead)

                – people are stupid for being in either of those lanes that merge when there is a third lane that doesn’t merge… (short sighted and dangerous) (no I won’t let them in! They should have thought ahead)

                –People are stupid (and selfish) for driving cars (dangerous, climate change)

                –People are stupid for thinking it’s reasonable to live without a car (missed opportunity to get ahead)

                Not me though, I consider everything from all sides all the time no matter what. Anyone that doesn’t invest their time like this to make decisions is… stupid. (/s)

      That the bottom 25% of scorers in standardized tests are in the bottom quartile of the distribution, which is literally defined as the bottom 25%, but the Twitter user seems to be using that fact to justify something yet he’s literally just stating a fact?

      The bottom 25% will always exist and there will always be 25% of the results contained within it.

      Not sure how anyone doesn’t get it, but this Twitter screenshot exists, so there’s that.

      Oh, sorry, this “x” exists. Dumb fucking name.

      I’m overthinking this.

      If everyone gets the full mark, it’s not a random variable anymore, you would have a collapse of the probability distribution, that would tend to a Dirac delta function. In this case, the very definition of “quartiles” would fail. So, yeah, there would be no one there because it wouldn’t exist.

      No, this is how a graph showing quartiles will always look because quartiles, by definition, always include a fixed percentage of the studied population under them.

      In this case the lower quartile will always have 25% of the population under it, 50% under the second quartile, and 75% under the third quartile.

      Quartiles break a population into 4 equal portions.

        Spendrill is not misunderstanding the OP. He’s just saying that if intelligence could be measured by a better metric, then distribution of that metric among the population would not look as smooth as the one in the OP.

          Not if you’re breaking the data into quartiles. Holy shit, do you really think the curve will be any different? Really? All that will happen is that some people will move around in the distribution. And the smoothing does not at all relate to how intelligence is measured but rather how it’s reported - in this graph.

            Yes I think it’s very possible that if you were to graph a population’s Intelligence using a some empirical score, then it has a high probability to NOT look exactly like a normal distribution.

            For example, let’s say that there was some score called “intelligence score” that scores people’s intelligence from 0-100. Do you think that if you were to graph a given population’s “intelligence score” that it would be EXACTLY centered around 50 in a Normal distribution? I think that’s unlikely. It’s more likely that there would be local maximums or minimums, or various skews in the graph. There could be a small peak at score 75, or a trough at 85. There could be all sorts of distributions.

            And guess what? Given this hypothetical distribution, you could STILL draw lines somewhere on the graph showing quartiles. Those lines might not be at 25-50-75. They might not even be the same distance apart from each other. But you CAN draw them somewhere to split the scores. Just because a graph “has quartiles” does not mean it will always look like the OP.

        It’s also, there are several different axes that you could measure intelligence along, spatial intelligence and awareness, emotional intelligence and so on. Also intelligence is a sliding scale, there are definitely times of the day, week month and year when I am less able to solve problems and more likely to cause them and then you’re into the social aspects, it’s been demonstrated that people’s ability to think straight is affected by how precarious their existence is and so on.

        If you took a test as a child, it was probably WISC-V.

        This assessment provides the following scores:

        • A Composite Score that represents a child’s overall intellectual ability (FSIQ)
        • Primary Index Scores that measure the following areas of cognitive functioning: Verbal Comprehension Index (VCI), Visual Spatial Index (VSI), Fluid Reasoning Index (FRI), Working Memory Index (WMI), and the Processing Speed Index (PSI).
        • Ancillary Index Scores are also provided: The Quantitative Reasoning Index (QRI) ; Auditory Working Memory Index (AWMI); Nonverbal Index (NVI); General Ability Index (GAI); and the Cognitive Proficiency Index (CPI).

        Which seems very reasonable to me. This was originally intended to be an aptitude test, not strictly to measure your intelligence.

            I don’t know, when I got tested it seemed like they were testing the right stuff.

            I’m pretty sure it’s a well-made test that provides fairly accurate results. Even if what they claim to be measuring in each category isn’t reflected in the test, it is, at the very least measuring the abilities required to take the test and that exactly.

            It seems pretty straightforward to see how good a kid is at solving a puzzle, right?

          You could have communicated much more clearly. It was not at all clear that you understood the post and wanted to have a specific side discussion. It read like you were taking the post at face value to discuss the failure of IQ testing. It especially even more like a misunderstanding because the post wasn’t even about IQ tests, but standardized tests. In fact, your top level post and this one I’m responding to both felt snide to me. First snide about the graph and IQ tests, then snide about the fact that people didn’t understand your unclear communication. You came off as one of those snide reddit users zooming past the post to make a point, especially with your aggressive defenses. Slow down. Consider your messaging more carefully.

            I was definitely critical of the graph and of IQ. It’s a flawed concept created by people who were at best blind to cultural differences and at worst outright racist. [I’m sorry if you found my messaging unclear]<— I’m being absolutely genuine here, I was trying to make a serious point and if you misunderstood it then perhaps I could have been clearer.
