An IQ of 74 is generally considered in the Borderline Intellectual Functioning range (70-79), indicating below-average intelligence that might present learning or adaptive challenges, though it's just above the threshold for Intellectual Disability (typically below 70) and is often seen as requiring support, not a severe deficit, according to Sydney Child Testing and Verywell Mind. While it's not "average" (90-109), it's close to the bottom 2-8% of the population, suggesting potential difficulties with complex tasks but not necessarily inability to function.
The average IQ score is 100, with a standard deviation of 15. So, a score of 74 is almost 1.75 standard deviations below average. It is almost in the ``mental retardation'' range (a score of 70 or lower is considered intellectually impaired) . A person in this scor...

Diagnosing Intellectual Disability
A full-scale IQ score of around 70 to 75 indicates a significant limitation in intellectual functioning. However, the IQ score must be interpreted in the context of the person's difficulties in general mental abilities.
Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs).

Recent research out of Harvard, Stanford, and the University of Pennsylvania suggests that while raw IQ may not increase dramatically, certain cognitive skills that contribute to performance on IQ tests can be improved through targeted training.
Individuals with borderline intellectual functioning (BIF) have cognitive abilities that range between average intellectual functioning and intellectual disability (ID) and correspond to an intelligence quotient (IQ) between 71 and 84 [1].
In the early 2000s another large epidemiological study reported that an IQ < 70 was observed in only 50% of children with ASD (6), while a more recent epidemiological study (7) reported a further decline toward an amount of 31% of children with ASD, that were classified in the range of cognitive impairment (IQ < 70).
Studies have shown that intelligence has a genetic component, but they have not conclusively identified any single genes that have major roles in differences in intelligence. It is likely that intelligence involves many genes that each make only a small contribution to a person's intelligence.
Lady Gaga's IQ is widely rumored to be around 166, placing her in the "exceptionally gifted" or genius category, though this is an estimation often cited in celebrity lists, not a officially verified number from a public test.
