IQ: Ranges, Meaning, and Achievement

This Thread is intended to present material on IQ research that will be explored by all members that wish to participate. Arguments both for and against (as well as neutral) are all welcome. If members have further research/findings they would like to present, by all means, please do so--any & all contributions are encouraged.


Consider, a normal IQ score falls between the range 85-115 which is approximately 70% of the population (and only 15% of people have an IQ of 115 or above), while an extended average IQ range tends to encompass those between 80-119 which is "x"% of the population. In order to qualify for the International High IQ Society, one must have an IQ of 125 or above, while entry into Mensa (a High IQ organization that represents the upper 2% of the population) requires an IQ of 2 standard deviations above average (or 130 and above). For the lower end of the bell curve, this will be explored later on in the post (as well as a more proper breakdown of the rest of the distribution).

Now, what do these numbers mean? That is, in principle, what can one do with a 100 IQ? It turns out, many studies have been done linking average IQ scores to completion of College Majors, SAT scores, and GRE (set aside the problematic elements for a moment, of which we can explore later). As for College Majors, studies have revealed a strong correlation for between those who go far into/complete specific college majors and IQ. The breakdown is as follows:

Top End of Spectrum

-Physics & Astronomy (133)
-Mathematical Sciences (130)
-Philosophy (129)
-Materials Engineering (129)
-Economics (128)
-Chemical Engineering (128)
-Other Engineering (128)
-Mechanical Engineering (126)

Bottom End of Spectrum

-Administration (107)
-Home Economics (106)
-Special (106)
-Student Counseling (105)
-Early Childhood (104)
-Social Work (103)

In order to attend College and be successful, it was found that an IQ of 110-115 is standardly required. Now, if a person with a 110-115 IQ attempted to be a Physics & Astronomy major, it has been found that they would quickly run into trouble and likely have to drop out (or fail out) early on. However, they would be successful at other college majors, some of which were listed previously. Then, an individual with a 100 base IQ has been shown to not (currently) be able to attend college successfully.

To put this in practical terms, lets take the example of those with an IQ 2 standard deviations from the norm in the *adult population* (2% of the population), or Physics & Astronomy combined with Mathematical Sciences Majors (closely followed by Philosophy and certain Engineering Majors, but we will limit our discussion to those past the threshold). This indicates that if we took a random sampling of 100 adults, approximately 2 would have a mind currently capable of the "brain power" necessary to do Complex Analysis or Statistical Mechanics (which is in-line with Senior level Physics or Math major cognitive abilities). As for what a 115 IQ would look like in practical terms, such a person would (currently) struggle tremendously to get a Political Science degree if they were able to attain it at all (IQ 120), while they would be able to get a degree in Business (114), Education (110), ect. See list here for more details: [https://thetab.com/us/2017/04/10/whi...ghest-iq-64811)

Now, IQ links to Standardized Tests such as the SAT and GRE are quite interesting as well--let us proceed with investigating the case of SAT scores. We will use the 1600 score standard (Note: a link to conversions between 2400 to 1600 score standards will be provided under *Sources* if one were curious). Consider, a score of 925 on the SAT (is claimed) to translate to a base 100 IQ. Here is an outline mapping out key points on the Bell Curve:

IQ, SAT, Meaning

- 55, 400, Trainable Moderate Mental Retardation
- 66, 525, Mild Mental Retardation
- 75, 630, Borderline Mental Retardation
- 87, 775, Dull
- 100, 935, Average
- 113, 1100, Bright
- 120, 1200, Very Bright
- 130, 1310, Extremely Bright
- 141, 1445, Briliant
- 151, 1575, Very Brilliant

For convenience, a few figures converted to the 2400 point scale (conversion chart here- [https://blog.prepscholar.com/new-sat...00-to-new-1600) ):


- 75, 820
- 87, 1020
- 100, 1260
- 113, 1510
- 120, 1670
- 130, 1840
- 141, 2070
- 151, 2340

[Note: There are various IQ scales, some reach to numbers higher well higher to this, this is a Standard Scale, others could be used with similar (though varying in extent) results]
Follow this link to find an IQ Reference Table which outlines IQ ranges and typical corresponding abilities:

Below is a transcription of the outline (IQ range, Category, Typical Ability):

1. 0-24
Profound Mental Retardation
Limited or no ability to communicate, eat, bath, dress and toilet.

2. 25-39
Severe Mental Retardation
Limited ability to communicate, eat, bath, dress and toilet. No academic skills.

3. 40-54
Moderate Mental Retardation
Some independent self-help skills and very basic academic skills.

4. 55-69
Mild Mental Retardation
Usually able to dress/bath independently and can do simple jobs. Elementary school academics.

5. 70-79
Border Line
May live independently with difficulties. Can perform simple and repetitive jobs.

6. 80-89
Low Average
Can complete vocational education and live independently.

7. 90-109
Can complete high school graduation and college with difficulty.

8. 110-119
High Average
Typical level of college graduates.

9. 120-129
Typical level of persons with doctoral degrees.

10. 130-144
Capable of understanding highly, complex academic material.

11. 145-159
Exception intellectual ability and capable of looking beyond known facts.

12. 160-175
Extraordinary genius
Extraordinary talent like Albert Einstein

The two best IQ tests on the internet are provided below (Note: most internet IQ tests fail to give a reasonable ballpark of the takers abilities, as they operate on internally 'rigged' algorithms to produce a non-relevant result)

(1) https://www.123test.com/culture-fair-intelligence-test/ (Note: there is a free 'very' condensed IQ test that will provide a rough ball-park of what range you should expect to fall into if you take the full length test)

(2) https://www.us.mensa.org/join/mht/

[Note, both tests require a fee ($9 and $18)]

The test from (1) is the only online test that has been refereed & deemed applicable for entrance to The International High IQ Society if one achieves a score 124 or above (or, higher than 95% of the population). Other ways into the society include Mensa intelligence test, Mensa membership, IQ test in person administered by professional(s), SAT score that is above the necessary mark.

Test from (2) is provided by Mensa as a Practice test. Mensa requires that one submit SATs, take a Mensa full length test in person, or an IQ test administered by a Psychologist all with translated scores 2 standard deviations above the norm (or, 130 for 15 sd & 132 for 16 sd). The Practice test is designed to give one a solid picture of the type of score they could expect to earn if they followed through and took the full-length Mensa intelligence test at one of their locations and dates (such tests are administered throughout the country relatively frequently, testing fee is about $60--compare that to a Psychologist administered intelligence test, which will cost easily upwards of $500)

Thus, if one does well on the Mensa practice test (i.e. 132 or above), it would be worth taking a full-length test offered by Mensa at a testing center at some point (if desired/curious), as there is a very strong likelihood of testing in & earning admittance to the organization
Note: Mensa and The International High IQ Society are the largest high IQ societies in the world
See High IQ societies:

(A) www.free-iqtest.net/high-iq-societies.asp
(B) https://www.iq-test.net/top-9-international-high-iq-societies-35.html


In addition to my previous post, one of the best ways to test your IQ on the internet (or even generally) is to take the SAT (if one has no to very limited College experience (i.e. 1 year or less) or the GRE (if one has graduated College or is just about to graduate). Now, for those in the middle of College or toward the end of College debating which test to take, either would work (i.e. SAT or GRE) or perhaps blend your two scores together if the SAT turns out significantly higher than the GRE.

Legitimate free tests can be found online, as well as SAT, GRE to IQ conversion tables. This will give one a pretty good sense of what their IQ is. Also, administered practice tests can be found at centers for a fee.

Note: These are typically about 4 hour long tests

If anyone is interested in where to find the requisite sources to carry out the examination as well as conversion to IQ, links can be provided

Congratulations, B ! You have completed the IQ TEST !!!

Your IQ is 122 in the intelligent category (14% of the population ratio)

Note: If your IQ scores is > 130, please send your information to us by using the form Here so we can update your result to our High IQ members board.

Share your IQ test results with friends

IQ tests on paper usually never cover the full extent of a person's abilities. They don't leave room for a multitude of possibilities based on the patterns observed. They also leave it open ended for the interpretation. Therefore who's to say which interpretation is the correct one? Having a defined answer limits the test's ability.
