Is it possible to have an IQ of 200+?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

IQ Scale
Over 140 - Genius or almost genius
120 - 140 - Very superior intelligence
110 - 119 - Superior intelligence
90 - 109 - Average or normal intelligence
80 - 89 - Dullness
70 - 79 - Borderline deficiency in intelligence
Under 70 - Feeble-mindedness
Normal Distribution of IQ Scores
50% of IQ scores fall between 90 and 110
70% of IQ scores fall between 85 and 115
95% of IQ scores fall between 70 and 130
99.5% of IQ scores fall between 60 and 140
Low IQ & Mental Retardation
An IQ under 70 is considered as "mental retardation" or limited mental ability. 5% of the population falls below 70 on IQ tests. The severity of the mental retardation is commonly broken into 4 levels:
50-70 - Mild mental retardation (85%)
35-50 - Moderate mental retardation (10%)
20-35 - Severe mental retardation (4%)
IQ < 20 - Profound mental retardation (1%)
High IQ & Genius IQ
Genius or near-genius IQ is considered to start around 140 to 145. Less than 1/4 of 1 percent fall into this category. Here are some common designations on the IQ scale:
115-124 - Above average
125-134 - Gifted
135-144 - Very gifted
145-164 - Genius
165-179 - High genius
180-200 - Highest genius

The person with the highest recorded IQ was Marilyn vos Savant, who scored as high as 230.
Here is an explanation from wikipedia:
-quote-
The two methodologies yield similar results near the middle of the bell curve, but the older ratio IQs yielded far higher scores for the intellectually gifted— for example, Marilyn vos Savant, who appeared in the Guinness Book of World Records, obtained a ratio IQ of 228. While this score could make sense using Binet's formula (and even then, only for a child), on the Gaussian curve model it would be an exceptional 7.9 standard deviations above the mean and hence virtually impossible in a population with a normal IQ distribution (see normal distribution). In addition, IQ tests like the Wechsler were not intended to discriminate reliably much beyond IQ 145, as ceiling effects become a concern.

There is also different kinds of "smarts" as there are street smarts, game show smarts, and book smarts. Ken Jennings had game show smarts, and was the highest scorer ever on Jeopardy as also shown in the below video.
