Exercise 1: Why Blamelessness Is a Practical Mechanism — Possible Solution
====================================================================

WHAT BLAMELESS ACTUALLY MEANS, PER THIS CHAPTER
------------------------------
Per this chapter, "blameless doesn't mean nobody is ever accountable,
or that mistakes don't matter. It means the review focuses on systemic
and process causes... rather than individual blame." It's a choice
about where the review's attention goes, not an absence of standards.

THE MECHANISM THAT MAKES IT PRACTICAL
------------------------------
Per this chapter, "if an engineer who made a mistake fears personal
blame for it, they're incentivized to omit or soften that detail in
the review - which means the review's own account of what happened is
now wrong." Fear of blame creates a direct, predictable incentive to
withhold or distort information - not because people are dishonest,
but because self-protection is a completely normal, rational response
to a threatening situation.

WHY A WRONG ACCOUNT MAKES THE WHOLE REVIEW FAIL AT ITS JOB
------------------------------
Per this chapter, "any fix aimed at a wrong account of events is aimed
at the wrong thing." A review's entire purpose is producing an accurate
understanding of what happened, so that action items address the real
cause. If key details are hidden out of fear, the resulting root-cause
analysis and action items are built on incomplete or false information
- meaning the review can produce confident-sounding conclusions that
don't actually address what really happened.

WHY THIS IS A PRACTICAL ARGUMENT, NOT A "BEING NICE" ARGUMENT
------------------------------
Per this chapter, "blamelessness isn't charity toward the individual;
it's what makes the review's own data trustworthy enough to actually
act on." The argument isn't about kindness for its own sake - it's
that blame-driven information-hiding directly undermines the review's
practical goal of preventing recurrence, regardless of anyone's
intentions.

WHY THIS WORKS AS AN ANSWER
------------------------------
It explains the specific causal mechanism (fear producing hidden
information producing a wrong account) rather than treating
blamelessness as simply "the nicer approach," and connects it directly
to why an inaccurate review fails at its actual job.
