Exercise 1: Why the Technician Never Mentioned the Extra Details — Possible Solution ==================================================================== WHAT ACTUALLY HAPPENED IN THE EXAMPLE ------------------------------ Per this chapter, when interviewed, the technician said "I just restart the service and check the logs." When actually observed performing the task, they "also check a specific configuration value first, and wait a specific amount of time before checking logs at all - details they never mentioned." WHY THIS WASN'T DELIBERATE WITHHOLDING ------------------------------ Per this chapter, "neither detail was a secret; neither was consciously remembered enough to say out loud." The technician wasn't choosing to omit information - the two extra steps had become so routine and automatic to them that they no longer registered as distinct, describable actions at all. Asked to summarize what they do, they described the parts of the process they're still consciously aware of doing, which turned out to be an incomplete picture of their actual behavior. WHY THIS IS A GENERAL PROPERTY OF EXPERTISE, NOT A FLAW IN THIS ONE PERSON ------------------------------ Per this chapter's own earlier point, "people are notoriously bad at fully verbalizing procedural knowledge they perform automatically - steps that have become second nature get silently skipped." As a person becomes more expert at a task, more of the task moves from deliberate, consciously-tracked action into automatic behavior - which is precisely what makes them fast and reliable at it, but also precisely what makes their own self-report of "what I do" increasingly incomplete over time. WHY THIS MEANS THE INTERVIEW ANSWER WASN'T WRONG, JUST INCOMPLETE ------------------------------ "I just restart the service and check the logs" wasn't a false statement - it accurately described the parts of the process the technician could consciously access and articulate. The problem is that conscious accessibility and actual behavior aren't the same thing, especially for a well-practiced expert, which is exactly why this chapter treats interviews as unreliable on their own rather than simply less detailed. WHY THIS WORKS AS AN ANSWER ------------------------------ It restates what specifically was missing from the interview, explains why the omission wasn't intentional but a natural consequence of expertise making steps automatic, and explains why this makes the interview answer incomplete rather than dishonest.
