Why This Book Matters
I’ve helped plan a few of those trips. The cost is real, and invisible, because nobody runs the comparison group that would expose it.
Any field that runs on inherited belief instead of evidence pays a tax, in money spent on things that don’t work. The campaign that books the phone bank every cycle because campaigns book phone banks is paying it; so is the trade association that flies its members to the capital each spring because it did last spring.
The fix is almost embarrassingly cheap. We report motion — meetings taken, op-eds placed, alerts sent — and call it results, when the job was to move a number. So next time you run an advocacy push, hold back a random slice of your list, send them nothing, and compare. That one thing separates a team that can report its activity from one that can prove its effect. The catch is temperament — we’d rather not find out our best tactic does nothing.
Issenberg describes a literal dumpster where a campaign’s hard-won data ends up. It’s real. I’ve watched it get filled.
This one cost me something. On a provincial campaign I worked on in 2011, we tried things that were new for a Canadian political campaign, much of it drawn from my time on the 2008 Obama campaign. We lost, so we never sat down afterward to ask what had worked. Plenty of it had. But to the victor go the spoils, and the losing side’s innovations get thrown out with everything else.
What We Cover in the Episode
- The New Haven experiment, and why it was the first field experiment of its kind in 70 years
- The three mechanisms that make the book work: the experiment itself, micro-targeting, and turnout as a measurable craft
- Hal Malchow’s polling flip — more about who voters are, less about what they think — and Alex Gage’s “consideration score”
- The neighbours letter, social proof, and the line between what works and what you can decently use
- Three mental models: the Lore Tax, the Untestable Channel, and the Margin Game
- Four ways the book gets misread, and four ways to use it in public affairs
- The mastery lesson: why the best operators are the ones willing to be proven wrong
Bonus: ideas that didn’t make the episode
It also means that, more and more, what a campaign acts on is a statistical guess about you, built from people who aren’t you.
The voter who is mostly a guess. Once campaigns ran out of people they’d spoken to, they started building “virtual” voter files: take the few thousand real conversations you’ve had, and project them across millions of strangers who resemble those people. It works.
The colourful variable is almost always the trap.
The seductive, useless correlation. Half the fun of the book is watching clever people get drunk on data. Most Jaguar owners lean one way politically — true, and worthless, because there are almost no Jaguar owners to knock on. The consumer “clusters” that vendors sell will file a homeowner right next to the man who cleans his pool. As the pollster Mark Mellman warns, you inherit whatever divisions the marketers drew, and their reasons were never yours.
Which is also why a neighbour on the doorstep beats the most elegant argument.
Why anyone votes at all. A single vote almost never decides anything, so a coldly rational person would stay home — which makes turnout a standing puzzle for economists. The researchers’ answer is the foundation under the whole book: the payoff for voting is social and psychological rather than instrumental. We vote because of who it makes us, and who is watching.
People lie about voting. Far more people tell you they will vote, and tell you they did, than ever turn out. (Roughly the share who say they go to church most weeks — then go count the cars in the lot.) So campaigns learned to trust what people did over what they said, and even to discount their own volunteers’ cheerful reports, because we save our politest fibs for a friendly face.
Presence outlasts noise here too.
The candidate who shows up. Tucked into the back half is a finding for anyone tired of the ad arms race. When a candidate physically turns up in a media market, the warm local coverage that follows moves numbers, and the bump holds. The lift from a television buy fades about as fast as you stop paying for it.
