Exercise 1: What's Wrong With the "Faster Horses" Justification — Possible Solution
====================================================================

Two separate things are wrong here, and they're worth untangling
individually.

First, the quote itself is on shaky ground - it is widely considered
apocryphal by historians, with no documented source in Henry Ford's
own writings or speeches. Citing it as authoritative evidence for a
real business decision is citing something with no verified basis at
all.

Second, and more importantly, even if the quote were genuine, the
conclusion being drawn from it doesn't actually follow. The real,
evidence-based lesson researchers rely on isn't "never ask users
anything" - it's that what users say they want in an interview and
what they actually do with a product are two different, complementary
kinds of data, and good research uses both rather than either one
alone. Skipping research entirely throws away real information a team
would otherwise have - it doesn't protect the team from a users-don't-
know-what-they-want trap, since the actual fix for that trap is
pairing interviews with real behavioral observation (usability
testing), not skipping research altogether.

ANSWER: The quote itself has no verified historical basis and is
widely considered a misattribution to Ford. Even setting that aside,
the conclusion drawn from it is a misreading of the real lesson - the
say/do gap is an argument for combining interviews with behavioral
observation, not an argument for skipping user research entirely.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly separates the factual problem (an unverified quote)
from the logical problem (a conclusion the real underlying research
doesn't actually support), matching the chapter's own two-part
correction.
