What American members say about the International High IQ Society

I love that IHIQS is a worldwide community

I’m so happy I was finally able to join IHIQS. There are times when I want to talk about specific topics in abstract ways, and the IHIQS community affords me this luxury. We talk about all sorts of things in our forums, from science to technology to art and beyond – it’s an incredible experience. Additionally, I love that IHIQS is a worldwide community, so that I can discuss opinions and ideas with people from different backgrounds and life circumstances than I have. Being an IHIQS member is one of the most rewarding and mentally-invigorating experiences available to us and I am thankful and proud to be part of this remarkable community.

The fluidity of ideas, mindful problem solving, the luxury of discussing boundless topics

Joining the IHIQS community has exceeded my expectations. It provides gratifying stimuli to witness and participate in harmonic interactions with like-minded individuals from all over the world. The fluidity of ideas, mindful problem solving, the luxury of discussing boundless topics that penetrate beyond the typical scratching-the-surface jargon and the support and understanding that emanate from each member to one another are incomparable to all other memberships or organizations I’ve experienced. It’s beautiful really. IHIQS has satiated the craving I have been seeking for what seems like the majority of my life.

IHIQS is an outstanding organization for individuals passionate about intelligence and learning

The International High IQ Society (IHIQS) is an outstanding organization for individuals passionate about intelligence and learning. As a retired Coast Guard aviator and executive chef, I value the unique opportunities it offers for engagement and growth. IHIQS fosters a welcoming community through events, discussions, and competitions, allowing members to connect and collaborate. The leadership is dedicated to supporting members in reaching their full potential and encourages continuous learning. If you’re looking to explore new ideas and meet fellow intellectuals, I highly recommend joining–IHIQS may even introduce you to a real genius to learn from!

IHIQS can be an instrument with which society can optimize the use of human resources

I joined IHIQS as an expression of my support for standardized tests in general, both as a flashlight (often the only) helping to identify talent in unexpected social strata, and in doing so, promote upward social mobility. IHIQS can also be an instrument with which society can optimize the use of human resources. In addition, I think that when 3,000+ exceptional intellects are brought together, they can eventually produce an undividable something that is much bigger than the sum of its 3,000+ parts.

Happy to have had the opportunity to satisfy my intellectual curiosity in IHIQS

I joined IHIQS in 2011. When I joined, I was in a systems engineering course in graduate school, searching for an outlet to participate in intellectual discussions. Surprisingly, I hoped to discuss music theory and emerging theoretical music research with like-minded people, but I have encountered so much more during my involvement in the organization. I think that people don’t often realize that, for some people, the need for intellectual stimulation is akin to the need to breathe; we must seek it, or else life is mundane, and the desires of our hearts remain unfulfilled. I am happy to have had the opportunity to satisfy my intellectual curiosity in IHIQS.

A place people genuinely want to return to

Joining the International High IQ Society has been one of the most rewarding decisions I’ve made. I’ve connected with many like-minded individuals through the forum, each bringing unique insights across a wide range of interest groups—from science and philosophy to the arts and beyond. What truly sets IHIQS apart is the warm, welcoming environment created by our incredible host, Alice, along with her dedicated team of group moderators. Their commitment to fostering thoughtful dialogue and mutual respect makes this a place people genuinely want to return to—both for stimulating conversations and the strong sense of community.

IHIQS is a sanctuary where members can meet and freely express themselves

I have discovered in IHIQS a sanctuary where members can meet and freely express themselves, away from the stereotypes that define “gifted.” Many of us experienced this bias growing up, and these experiences have often defined us in a negative way. As a creative, this particularly affected my writing and career choices. I used to wonder why I never “fit in”. I’m grateful that acknowledging this difference has returned me to my original path. In the IHIQS space, I have discovered a sanctuary that enables me to express myself authentically. The forums are a gateway to meet other like-minded members and communicate openly without the adverse and often disparaging reactions I have encountered over the years.
