Science Buddies: "Ask an Expert"

Hi I am looking for a reliable answer to this question from a reliable or peer-reviewed source, but I do not know what is a reliable or peer-reviewed answer to this question.

I have heard that IQ tests are not a reliable method to reliably measure someone’s intelligence and I have also heard that it is a reliable method. So I do not know what to make of this and wanted to hear from an expert in the related fields that pertain to IQ and human intelligence to tell me whether IQ really is a reliable method to measure intelligence or not

Hello, The Ask the Expert forums are for students in grades K-12 who are doing science projects. The experts do not answer general questions from non-students. There are other sites on the web where your questions will be more appropriate. Thank you.
