A Spy’s Guide to Spy Movies: Zero Dark Thirty

(This movie plus eleven more are in A Spy’s Guide to Spy Movies. It’s on Amazon here.)

Good thinkers don’t start with data.

Which sounds backward. After all, the DADA Chain goes like this: Data, Analysis, Decision, Action.

Data is at the beginning. Collect everything, then see what it says.

But the world is overflowing with data. Collect everything and you drown in it.

You need a way to limit it. A way to filter it. A way to focus on what’s important.

So scientists start with a hypothesis. Intelligence agencies start with the decision they’ll eventually have to make.

Then they go get the data that matters.

- - -

Zero Dark Thirty (2013) is about the ten-year hunt for Osama bin Laden, told through a CIA analyst called Maya, played by Jessica Chastain.

For most of a decade, the Agency chases the loudest data. Threats. Plots. Names that lead to more names. The files pile up.

And Bin Laden stays hidden.

Maya works from a hypothesis instead: a man like Bin Laden doesn’t use phones or the internet. He uses people. Find the courier he trusts, and the courier leads to the man.

One name keeps surfacing at the edges of other stories: Abu Ahmed. Detainees mention him. Then the record goes quiet. So quiet that the quiet itself becomes data.

A detainee claims Abu Ahmed is dead. For years, that closes the lead. Then an old file gives up the family name. And the truth: the dead man was his brother. The two looked alike.

The hypothesis shrinks a world of data to one question: Where is Abu Ahmed?

Analysis, step by step. A real name. A phone number.

Then they observe tradecraft on the phone: a man who drives for an hour before making a call is a man protecting something. The phone leads to a white SUV. The SUV leads to a compound in Abbottabad.

And the data from the compound fits the hypothesis. No phone line. No internet. Burns its own trash. Almost nobody in or out.

The data never says Bin Laden. It says: everything here is consistent with the hypothesis that it is him.

Then comes the third step. The decision.

There’s a scene near the end that most thrillers don’t film. A conference table. The director asks the room for a number: how sure are we?

The answers come back as percentages. Sixty. Eighty. A soft sixty. Maya says a hundred. Then she allows the room its caution: call it ninety-five.

That’s what a real Decision step looks like. Not certainty. Probabilities, stated out loud, each with a verdict attached. Because the data has run out. More collection won’t settle it. Somebody has to decide on incomplete information. Or decide to do nothing, which is also a decision.

Because the Action can’t be taken back. Helicopters into another country, on the strength of the analysis. If the compound holds only a courier and his family, the cost is enormous.

Data collection, careful analysis, an honest decision. All so the irreversible action has the best chance of being right.

The raid confirms the hypothesis.

The confirmation comes: it was Bin Laden.

Your problems drown in data, too.

The market research. The metrics dashboard. The inbox full of opinions about what’s wrong.

Take the decision you’ve been circling and write it as a hypothesis before you collect anything else. Not ’let me look at the numbers.’ Instead, write down a sentence that can be wrong: ’We’re losing renewals because the first week fails people.’ The hypothesis tells you which data matters. Everything else is noise.

Then when the data runs out, and it will, put a number on your confidence and give it a verdict in plain words. Seventy percent: good enough for a small bet, not good enough to bet the company. If you can’t say the number out loud to someone, you’re not at the Decision step yet. You’re hiding in Analysis.

It took ten years to find one man. Most of those years were spent collecting data. The hunt ended when a hypothesis told one analyst which data mattered. And when a room full of people said their numbers out loud. And acted.

Data, Analysis, Decision, Action.

Starting with a decision.

Which filters the data.

And focuses the analysis.

Which leads to action.

Data. Analysis. Decision. Action. Four links, fixed order. These books show the chain running. And breaking.

Superforecasting, by Philip Tetlock & Dan Gardner.
Tetlock found ordinary people who out-predict intelligence agencies. Their method: start with a hypothesis, collect data, update the analysis, decide. The chain, run in the open.

Thinking, Fast and Slow, by Daniel Kahneman.
Kahneman spent a career on one link: analysis. Where it works. Where it breaks. And why smart people miss the break.

Sources of Power, by Gary Klein.
Klein studied firefighters and pilots. People who run the whole chain in seconds, with lives on the line. This is how they do it.

The DADA Chain is one of six frameworks on the Spy’s Guide frameworks page, and it’s from A Spy’s Guide to Thinking.
