<p>I would like to know how psychologists come up with the questions they include in an IQ test and how they know that those questions will accurately measure intelligence? How has it been proved that IQ tests do indeed work?</p>

@Christian I can see that you feel that iq tag would be useful. Please discuss issue in [meta](http://meta.cogsci.stackexchange.com/) before engaging in mass retagging. If the community approves of this, only then do it. There is an argument that the iq tag is not required. i.e., many questions tagged intelligence are about iq; having both tags will mean that many people using the iq tag will fail to apply the broader discipline tag.

**Tags:** intelligence, iq
