Thanks for subscribing to Experimental History! It means a lot to me.

Here are my three most popular posts:

If I wrote something that made you think, I hope you’ll consider signing up for a paid subscription. Experimental History is the main thing I do, and subscribers allow me to do it. I say thanks to them with MYSTERY POSTS for their eyes only, including my “A Whole Negotiation Class in Three Posts” series that was inspired by the two years I spent teaching MBAS (Part I, Part II, Part III), plus posts like If You Have Imposter Syndrome Maybe You’re on to Something and How I Became a British Meme (long story).

If you can’t swing it today, that’s okay! My biggest posts will always be free.

Also, I have a book coming out! It’s called THE STRANGEST IDEA IN THE WORLD and it’s about the greatest mystery in human history: why did it take us 300,000 years to invent the toilet? (Short answer: because it seemed like a bad idea at the time.) Because it argues for a weird way of thinking, it’s also got a weird way of reading—there are nonlinear elements, hidden pages, multiple endings, and a bunch of other secrets I won’t spoil. You can get it here.
