In every company, and inside each of us, there are two forces: the one that's good at planning, and the one that's good at executing. Most of us lean hard one way. That's completely fine, until the moment we're in the wrong seat at the wrong time. And I'm writing this as someone stuck on the planner side of the equation, so let's be honest about it.

The two systems: the one who evaluates and the one who moves

Psychology describes two independent systems of self-regulation. The first is assessment: the tendency to compare, weigh alternatives, and judge quality until it's clear what's best. The second is locomotion: the tendency to move from state to state, to "make things happen" and keep going until they're done. Planners are strong in assessment and make high-quality decisions. Executors are strong in locomotion and generate momentum. The research is clear on one point: the best performers are high in both, but most people are not.

There's another layer. Researchers Heckhausen and Gollwitzer described the "Rubicon model": in every action there's a line where a wish becomes a will, where you stop deliberating and commit. Planners get stuck right before that line, polishing the plan instead of crossing it.

Which type are you?

No test will settle it for you, but the behavioral tells are clear:

The struggles: as an employee, a manager, an owner

As an employee, the planner gets labeled "slow" but makes the fewest costly mistakes, while the executor is seen as "reckless" but finishes fast and accumulates rework. As a manager, the over-planner becomes a bottleneck that delays decisions, and the over-executor changes direction every month and burns the team out with movement that has no direction.

The hardest seat for a planner is the business owner's, for a precise reason: there's no boss to hand them a scoped task. The Rubicon line, the "go" signal, is supposed to come from them. And that's exactly where excellent planners keep planning instead of starting.

If you're a planner: how to move

The surprising part is that the research on entrepreneurs says the opposite of the intuition. Sarasvathy studied 27 expert entrepreneurs, and 24 of them didn't start from a perfect plan. They started from the resource they already had, and from one question: "how much am I willing to lose to find out," not "how much will I make." They called it affordable loss. The start came before the plan.

If you're an executor: how to add assessment

If you're on the executor side, the leak is the reverse: movement without enough deliberation. Add assessment on purpose, a pre-mortem before a big move, a 24-hour rule on irreversible decisions, and one person whose job is to stop you. I wrote about that side separately, in exploitative poker and when the fold is the move.

When knowing more helps, and when it hurts

The intuition is that more knowledge always helps. But it cuts very differently for the two types.

For the executor, knowledge is almost always an advantage. Gary Klein studied experts who decide fast under pressure, firefighters, commanders, ICU nurses, and found they rarely compare options. They recognize the situation from experience-built patterns, generate a single move, quickly simulate how it plays out, and act. That's expert intuition. An executor without knowledge is reckless, but for an executor with deep domain knowledge, speed turns into a real edge. One caveat: Klein and Kahneman showed that this kind of intuition is reliable only when the environment is regular enough and gives fast, clear feedback. Poker has that to a degree, business much less.

For the planner, past a certain threshold, more knowledge can hurt. Two findings show it. First, Wilson and Schooler found that people who analyzed in depth "why" they preferred something made choices that matched expert opinion less, because the analysis focused them on the wrong criteria. Too much thinking weakened the decision. Second, and especially close to poker: Bilalic and Gobet showed that even chess masters get stuck on the familiar solution. When shown a familiar-but-suboptimal move alongside a better but less familiar one, the familiar move blocked the better one. It's called the Einstellung effect: the first idea that comes to mind steers attention toward it and away from the alternatives.

So for a planner, extra knowledge doesn't just feed analysis paralysis, sometimes it becomes learning as a way to avoid starting: "I'll begin once I know enough." There's a threshold of "enough to start," and past it you learn the most from one real attempt, not from ten more hours of reading. For the executor, by contrast, investing in knowledge and reps directly upgrades the intuition that's already driving them.

At the poker table

The pattern is especially visible in poker. A high-assessment player over-deliberates, second-guesses, and sometimes plays too passively. Their leak is hesitation: not pulling a profitable trigger. A high-locomotion player pulls triggers, applies pressure and adapts fast, but deliberates less in the moment and over-commits. Their leak is movement for its own sake.

The move

You don't need to become someone else. A planner doesn't need to turn reckless, and an executor doesn't need to turn slow. What you need is to recognize which side is strong in you, to know when it works for you, and to build a frame that completes the other side exactly in the moments it's missing.
