Madonna's IQ is 140 and Shakira's is 140. Neal Pert's is 150.
Stephen Hawking's is 160. Most top mathematicians are >160.
However, may I ask where you are getting these numbers? I see a lot of IQ numbers thrown around on the internet for celebrities and politicians. I don't know that any of these individuals have actually ever taken an IQ test let alone shared the #s publically. I also don't know that any person's IQ is an exact # so much as a range.
I know that most of these people have stated their IQ in interviews. Many are members of Mensa as well.
Given the responses thus far I can see that this thread is going to be contentious so I should probably bow out, but I feel the need to address this first.
Mensa requirements are 130. I also don't tend to believe everything Madonna or Shakira says in an interview. I can state that my IQ is 140. It doesn't make it so.
As a member of Mensa myself I do also have access to the online searchable member directory. All current members names are listed there. They may omit all other details (address, etc.) but I believe that their names would be there at least. No one with the first name Shakira is listed as a member. There are a very few Madonnas but I am quite certain based upon last names, ages, and addresses they they aren't
the Madonna. There is also no Steven Hawking or Neal Pert.
