Have you heard of The 5 Whys? It’s a Six Sigma tech­nique for dis­cov­er­ing the root of a prob­lem. Each why” gets you past sur­face ef­fects and closer to the cause.

It sounded good in the­ory, so I tried it on Lydia the other night when she did­n’t want to put her pa­ja­mas on.

Brian: Why don’t you want to wear pa­ja­mas?”

Lydia: Because I don’t want to.”

Brian: Why?”

Lydia: Because I don’t want to.”

Brian: Why?”

Lydia: Because I don’t want to.”

Brian: Why?”

Lydia: Because I don’t want to.”

Brian: Why?”

Lydia: Because I don’t want to.”

I’m not im­pressed with the tech­nique.
