Dr. Matt Walker was not on this episode. A recording of them was played into it, so these are their words but not an appearance on Masters of Scale. It still counts as said, and it is kept out of every score on their page.

“One of the more surprising facts is that the less and less sleep that an employee has had, the more and more likely they are to lie become unethical. So for example, falsify data in a spreadsheet.”

The claim, plainly

The less sleep an employee gets, the more likely they are to engage in unethical behavior such as falsifying spreadsheet data.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Dr. Matt Walker's assertion accurately reflects robust findings in peer-reviewed organizational psychology and behavioral science literature published prior to March 2023. Multiple landmark studies—such as Barnes et al. (2011) in Organizational Behavior and Human Decision Processes, Christian & Ellis (2011) in the Academy of Management Journal, and Welsh et al. (2014, 2018) in the Journal of Applied Psychology and Journal of Experimental Social Psychology—consistently demonstrate through both laboratory experiments and workplace field studies that sleep loss impairs self-regulatory capacity (ego depletion), leading to statistically significant increases in deceptive reporting, cheating, workplace deviance, and unethical behavior.

Barnes, Schaubroeck, Huth, & Ghumman (2011) established in four laboratory and field studies that reduced sleep quantity and quality directly increase cheating tasks and supervisor-rated unethical employee conduct via ego depletion.
Christian & Ellis (2011) demonstrated experimentally and observationally that sleep deprivation significantly elevates workplace deviance and unethical conduct.
Welsh et al. (2014, 2018) showed in laboratory experiments and natural sleep studies that sleep deprivation leads to significantly higher rates of deceptive reporting and cheating.
Gunia (2022) review in Current Opinion in Psychology corroborated that inadequate sleep reliably promotes workplace dishonesty, deception, and unethical decision-making.
