Why this is better

Corrected two journal/year misattributions: Levitt & List (2011) Hawthorne reanalysis appeared in American Economic Journal: Applied Economics, and the Wadhera et al. HRRP-mortality study was published in JAMA (2018), not NEJM (2019), per the article's own reference list. Verified already live in body content; FAQ had no mention of either study. Note: the bibliography's Wadhera entry itself still lists '(2019)' rather than the JAMA vol 320 issue 24 (Dec 2018) date, a separate, narrower discrepancy outside this contribution's described scope, left untouched and flagged for a future pass.
