It is a fact! There are half a dozen tests that Professionals use. Two major ones. And they change every year so it matters which version and year the clinician is using. Otherwise you cannot compare.

BTW, they change it every year so they can sell the newest version to clinicians every year for 2000 to 5000 USD.

Logically, what editions do you think the smaller countries are using?

@Stan ******

Yes, but do you have my BA in Philisophy an Master's in Organizational Management?

IQ tests are worthless.

@Stan ******

Man! Everything is about race to you.

BIGOT

Look, the mere fact that Thais can navigate bkk streets everyday without even a dent is awe inspiring.

@Stan ******

No, I have taken 3 "Professional" IQ tests in my life and each varied by 10 points. The highest being 127.

But it is all nonsense! Psychology is a Pseudoscience.

It is as Achemy is to modern Chemistry.

BIGOT

@Oliver *******

Because they all take different tests and there is so much fakery.

My guess is developing countries use the oldest, most standardized tests while the Indutrialized nations use the modern, Kaleidoscope tests.

@Stan ******

BTW,

BIGOT!

Cherry-Picking

Some IQ tests are overly generous to not hurt people's feelings.

The most standardized tests place the average at 90. It differs depending on what tests people take.

Some of the modern and less accepted tests do place the average at 100 (nice round number easy to understand for people with low IQ's)

My college minor was Psychology so don't comment on other people's IQ's.. Ever!

They don't really understand what IQ is. There are Savants with an IQ less than 70 that can play Mozart on the piano flawlessly.

@Oliver *******

90 IQ is the normal average everywhere. It the normal average IQ.
