About this app

There's no shortage of good learning material. The bottleneck is purpose.

We want answers to the big questions in fields we care about.
Are high interest rates good for the economy? Do trade wars help us? Did Keynes mean what the textbook says?
To take these seriously you dig past the headline — sometimes through an interactive chapter, sometimes through a traced lineage of each side, sometimes through an empirical atlas. The panels below show all three, on one example.

What’s new

The "Big Questions" are now Walkthroughs — 110+ of them, rebuilt from scratch. Guided paths through contested questions, from quick takes to deep multi-part arguments, each linking into the textbook's interactive charts and back to where you left off.

The two history books — Economic History and History of Economic Thought — are now interactive too: the charts respond as you change the assumptions.

Plus new chapters across all three books and reorganized navigation.
