Exercise 3: Comparing Power Posing's Collapse to the Stanford Prison Experiment — Possible Solution
==========================================================================================================

ONE GENUINE SIMILARITY: Both cases involve a real, hugely popular
finding that reached far beyond academic psychology into mainstream
culture - the Stanford Prison Experiment became a fixture of
introductory psychology courses and popular retellings for decades,
while power posing reached tens of millions through Cuddy's own TED
talk. In both cases, that popular reach meaningfully outran the
underlying evidence's own real strength, and in both cases, it took a
specific, dedicated, real investigative effort years later (Le
Texier's 2018-19 archival work; the 2015-17 replication attempts) to
seriously challenge the popular version of the story.

ONE GENUINE DIFFERENCE: The two cases diverge sharply in how the
ORIGINAL researcher responded to the challenge. Zimbardo has real,
publicly documented disagreement with Le Texier's critique and
continues to defend his own original interpretation of the Stanford
Prison Experiment. Dana Carney, by contrast, is one of power posing's
own original co-authors, and she didn't dispute the challenge to her
work - she went further than the replication evidence alone required,
publicly declaring in her own words that she no longer believes the
effect is real at all.

This makes the two cases genuinely different in kind, not just in
degree: the Stanford Prison Experiment remains a real, live, contested
scientific dispute between the original researcher and his critics,
while power posing has effectively been settled from the inside, with
one of its own original creators publicly agreeing with the critics'
own conclusion.

ANSWER: Similarity: both cases involve a hugely popular finding whose
real popular reach meaningfully outran its underlying evidence,
eventually corrected years later by a dedicated real investigation.
Difference: Zimbardo continues to publicly defend his own original
interpretation against Le Texier's critique, making that case a
still-live dispute - while Dana Carney, an original power-posing
co-author, publicly repudiated her own findings, effectively settling
that case from the inside rather than leaving it as an ongoing
disagreement between researcher and critics.

WHY THIS WORKS AS AN ANSWER
------------------------------
This identifies a real shared pattern (popular reach outrunning
evidence, later corrected by investigation) while correctly
distinguishing the two cases by whether the original researcher
disputes or agrees with the correction.
