[Verse 1] Grab a magnifying glass, I'm tracing the thread, One case, cracked wide open, every clue gets read. Process tracing means I walk the causal chain, Link by link, cause to effect, explaining the strain. Not a hundred countries, just a handful run deep, Depth over breadth, that's the bargain we keep. Stacks of paper, microfiche, the fingerprints of fact, I'm not guessing at the story, I'm reconstructing the act. [Chorus] Agreement, difference, that's the method key, Mill laid the tracks for the comparative spree. Most-similar cases, one thing splits the pair, Most-different cases, one thread still is there. Case by case, we're building up the proof, Process tracing underneath the roof. Hold the hook, don't let the detail slip, Cases and comparisons, that's the scholarship. [Verse 2] Say five countries rebel, what do they share in common? Strip away the noise till one cause keeps on. That's agreement — sameness pointing to the spark. Now flip it: two cases, nearly a carbon-copy mark, Identical twins except for a single variable, Difference in outcome makes that difference reliable. Most-similar design holds the background still, Most-different design says the outcome's the thrill Even when the settings don't resemble at all — Find the one factor standing tall through it all. [Verse 3] Nineteen seventy-eight, Fenno packs a bag, Rides along with Congressmen, no entourage, no brag. Town halls, diners, the Rotary Club chat, He calls it Home Style — the politics of habitat. Not a poll, not a graph, just boots on the floor, Watching how they talk to the folks at the door. Legend building, trust building, right there on the scene — That's what the numbers alone could never have seen. [Verse 4] Interviews pull secrets statistics won't show, Archives are a palimpsest — layers under the glow, Scratched and rewritten, the old ink still shows through, Read between the memos to find what's true. Ethnography means living inside the room, Watching the mechanism, not just the boom. Ask the interlocutor — the one who was there — A stranger in conversation who breathes the air Of the history you're chasing, the texture, the tone, Statistics give the skeleton, stories give it bone. [Bridge] Skocpol stacked France, Russia, China side by side, Peasant revolt, crumbling state, international tide. States and Social Revolutions, the structural frame, Comparative historical — she gave it a name. Not fate, not heroes, but conditions that align, Three nations, one pattern, drawn in a line. [Chorus] Agreement, difference, that's the method key, Mill laid the tracks for the comparative spree. Most-similar cases, one thing splits the pair, Most-different cases, one thread still is there. Case by case, we're building up the proof, Process tracing underneath the roof. Hold the hook, don't let the detail slip, Cases and comparisons, that's the scholarship.
