The Secret Map Every Paper Follows: IMRaD

Here is a secret that will make you feel you cracked a code. Nearly every scientific paper on Earth — in medicine, physics, psychology, engineering — follows the same four-part map. Researchers gave it a nickname: IMRaD — Introduction, Methods, Results, and Discussion.

You already learned every piece of it from Maya’s plants. IMRaD is just the professional order of boxes you know:

• ›I — Introduction: why this question, and what am I asking? (Maya’s curiosity, her gap, her hypothesis.)
• ›M — Methods: exactly what I did. (Maya’s recipe.)
• ›R — Results: what I found, just the facts. (Maya’s numbers.)
• ›D — Discussion: what it means, and what its limits are. (Maya’s judging and honesty.)

Wrapped around this core, a full paper adds a few layers: Title (the name) → Abstract (the trailer) → Introduction → Methods → Results → Discussion → Conclusion (the wrap-up) → References (the credits).

Once you know this map, no paper can intimidate you again. When you open a 20-page journal article you will simply think: “Ah — there’s the Introduction. There’s the Methods. Let me jump to Results.” You will navigate it like a local, not a lost tourist.

Now let’s actually write. And we’ll start where every paper starts — the Introduction — using a trick shaped like a funnel.
