9th WIN member society (since 12/2009)
IIS was founded by Jeffrey Osgood on January 30, 2007. The society’s main purpose is to have members who interact with each other in stimulating online forum discussions and to share in the camaraderie of society fellowship.
The society only accepts candidates who have performed on specific standardized IQ tests, and the results are analyzed by psychometricians with experience and knowledge about the latest research in high IQ testing.
