The Pyramid Principle, developed by Barbara Minto at McKinsey, is a method for structuring information clearly, logically, and persuasively.

Here’s how it works:

1. Start with the answer. (Lead with your main insight—don’t bury it at the end.)

2. Support it with key arguments. (Break down why this is true.)

3. Back up those arguments with evidence. (Provide qualitative & quantitative data.)

This flips the usual way research reports are written. Instead of working toward the conclusion, you start with it.

Think of it like a pyramid:

• Conclusion First

• Key Arguments

• Supporting Evidence

Instead of:

1. Background – Why we did this research

2. Methodology – How we did it

3. Findings – What we discovered

4. Conclusion – What it all means

We flip the structure:

1. Conclusion First – “Users aren’t converting because the sign-up process is too complicated.”

2. Key Arguments – “We found three primary reasons why: (1) Confusing UI, (2) Lack of trust, (3) Poor onboarding.”

3. Supporting Evidence – “40% of users abandon at step 2. Interviews reveal they don’t know what happens after sign-up.”

This ensures stakeholders get the most critical information first even if they only read the first page.
