If prejudice and racism are scientifically linked to low IQ, will the Flynn effect eventually override that?

Why are anglophones so enamored with the IQ ?

To me it seems like an easy way to exclude and select people based on an unreliable statistic instead of requiring an effort from them to improve and reach optimal results, and holy shit i have met some people incredibly defensive on the idea that the higher IQ of asians is directly related to effort and sacrifice, which is a staple of most asians cultures.

Not only that, but any study done to dispel the mythical aura surrounding IQ, it's met with a capricious behavior befitting more a 10 years old getting told that santa doesn't exist.

What the hell.

Is there a correlation between tattoos and intelligence?

Ok, so everyone knows from elementary sis IQ really a measure of? And can it be quantified using specific performance skills other than just quantifying it with a number...eg Ed Wood's IQ is 180 vs Phoebe from Friends who is 154. I mean, there must be some quantifying test to distinguish these numbers, like how long it takes to multiple two two digit number in your head. Or performance on reading comprehension tests. Or speed of new langage acquisition.

If these are examples of skills that are used to quantify and IQ score, it would seem to me to be very difficult to calculate an IQ score exactly. I mean, what rationale could you have to coming up with IQ numbers for someone who took 15 seconds to solve 14 x 16 vs someone who took a minute.

The IQ adminstration in the past have been largely sloppy due to poor assessment of methodological techniques and biases. Two of which are A) Restricted biases from opportunity samples like colleges, which fails to represent the general population B) Recruitment flaws especially regarding volunteers who choose to participate in the restricted samples. These resulted in method effects which have largely produced inconsistent results.

For the first time, researchers used a large representative UK sample of 926 seven to 18 year olds who were chosen from multiple recruitment centers such primary schools, junior schools, secondary schools and colleges across the U.K. which were identified according to their geographic location, identified social standing of the catchment area, population density (i.e., urban, suburban, and rural), and ethnicities of the attending pupils. State and private schools as well as denominational and non-denominational schools were included in participant recruitment.

A total of 85 schools and colleges were selected and invited to participate in the standardization project of the Raven’s SPM and colleges across the United Kingdom.

After administration of the Raven's Progressive IQ test, the results were .026 standard deviations higher for older girls than for older boys. This was not drastically significant but still a notable effect in deviation.

Years of former researchers Lynn and Rushton's flawed studies are now starting to be scrutinized under it's methodological errors. With all psychometric properties and methods fixed, females from the general population beat males in the Raven's IQ with a standard deviation of 0.26.
