The alignment illusion
A transformation is announced, discussed, workshopped and signed off. Every step produces the same artifact: expressed agreement. But expressed agreement is a statement about words, and the transformation will be executed through cases — thousands of small classifications of what the new strategy means here, in this decision. Nothing in the alignment meeting tested whether those classifications converge.
The error is not random — it is directional
In 1990, Stanford psychology researcher Elizabeth Newton had people tap the rhythm of well-known songs on a table while listeners tried to name the tune. Of 120 tapped songs, listeners identified 2.5%. The tappers had predicted 50%. The study — documented by Chip and Dan Heath as a demonstration of the curse of knowledge — shows two things at once: whoever knows the melody hears it in their own tapping and cannot reconstruct the state of not knowing it; and the resulting error is not noise but systematically optimistic, here by a factor of twenty.
This is why “I asked, and everyone said they understood” settles nothing. The speaker’s confidence and the listeners’ confirmation are produced by the same mechanism — each side hears its own complete version. The reassurance is the artifact, not the evidence.
Learning cost or execution cost — the only real choice
Interpretation gaps do not disappear when they are ignored; they change their price. Discovering divergence before sign-off is a learning cost: a harder meeting, an uncomfortable question, a delay measured in days. Discovering it afterwards is an execution cost: parallel versions of the strategy built into hiring, budgets and products, paid for with interest. Transformations rarely fail because people disagree — they fail because nobody measured whether the agreement was about the same thing.
What works instead
The bias cannot be trained away — Newton’s tappers still heard the melody after learning about the effect. What can change is whether you rely on it: replace the leader’s guess about how well the message landed with an actual measurement of how people classify concrete cases. The guess doesn’t get better; it becomes unnecessary.
