Pros
There are a lot of opportunities to develop intellectually and learn about the ideas from an expert rather than from a book directly.
Cons
The leaders of IHS, at their best, lack empathy. And I mean that about every single member of the leadership team- even those who are perceived as above the fray. At their worst, leadership purposefully promotes a toxic culture that pits individuals against each other, elevates paranoia to an extreme level, and makes it seem like petty gossip without context is ok. I have experienced this first hand. As almost every review has mentioned, you will only climb the ladder at IHS if you're a yes man and, even then, your favor may not last long. IHS has taught me a valuable lesson in how not to treat people and that is something that I will take with me throughout the trajectory of my career so, in some twisted way, I am grateful to them. That said, some of the most dehumanizing experiences of my life were the result of working at IHS and I will feel the impact of it for years to come. My advice to young libertarians hoping to have an impact on the movement: look elsewhere... for your own personal wellbeing. The reviews here are not wrong.
