Authority Bias
Authority bias is the tendency to assign greater accuracy and weight to an opinion, instruction, or recommendation because it comes from a perceived authority figure, independent of the actual content or merit of that opinion.

Milgram obedience baseline
26 of 40 participants (65%) administered the maximum 450-volt shock despite the learner's protests; Milgram and others had predicted only ~1-3% would.

Hofling nurses field study
21 of 22 nurses began to comply, despite hospital rules against phone orders and unauthorized drugs; in a separate survey of 33 people (12 nurses and 21 nursing students), all but two (~31 of 33) said they would not comply.

Bickman 'social power of a uniform'
Compliance rose sharply with authority dress; for the parking-meter dime request, ~89% obeyed the guard vs ~57% the milkman and ~33% the civilian (figures as reported in secondary summaries of the study).

Engelmann expert-advice fMRI
Expert advice shifted probability-weighting in the advised direction and participants followed advice on 72.81% of trials vs 64.10% without; value-correlated activity in valuation regions disappeared under advice, suggesting neural 'offloading' to mentalizing regions.

Final disposition
Admitted w/ caveat
The umbrella effect (status/expert cues sway judgment and behavior) reproduces across paradigms, but the flagship obedience evidence is contested. Burger (2009) ran an ethically constrained partial replication of Milgram and found 70% continued past 150V, statistically indistinguishable from Milgram's comparable rate, suggesting the obedience effect is not era-bound. However, the interpretation of what Milgram demonstrated is disputed (Haslam and Reicher's 'engaged followership' re-analysis; Hollander and Turowetz's critique), and Milgram's original work draws methodological and ethical criticism. The Engelmann fMRI study is a single small-sample (n=24) experiment not yet broadly replicated. Bickman's uniform percentages are widely cited but specific figures vary across retellings. Treat the behavioral effect as fairly robust and the mechanistic/obedience interpretation as genuinely contested.

Handling note · how it gets waved through
Two non-exclusive mechanisms are proposed. (1) Heuristic/cognitive offloading: treating an authority's view as a reliable shortcut frees the individual from effortful evaluation; Engelmann et al. (2009) found that under expert advice, brain regions normally tracking option value stopped doing so while theory-of-mind regions (temporoparietal junction, dorsomedial PFC) engaged, consistent with deferring the computation to the trusted source. (2) Social/normative deference and obedience: people comply with legitimate authority because of internalized norms, perceived legitimacy, and situational pressure, as in Milgram and Hofling.
Competing account — Haslam and Reicher argue Milgram's results are not blind obedience but 'engaged followership' — participants identify with the experimenter's scientific cause and act because they believe it is worthy, not because authority overrides conscience. Hollander and Turowetz (2018), drawing on archived audio, dispute that engaged followership operated as claimed and propose multiple distinct compliance processes. So whether 'deference to authority' is a unitary mechanism at all is contested.
Seen in the field
aviation · 1997
Korean Air Flight 801 crash, Guam
On 6 August 1997 a Boeing 747-300 crashed into terrain near Guam, killing 228 of 254 aboard. The NTSB cited the first officer's and flight engineer's failure to monitor and challenge the captain's flawed non-precision approach; analyses attribute the silence partly to a steep cockpit authority gradient in which junior crew were reluctant to challenge the captain until seconds before impact.
finance · 2008
Bernard Madoff Ponzi scheme and SEC oversight failure
Investors, feeder funds, and even regulators deferred to Madoff's stature as a former NASDAQ chairman and perceived trading expert, accepting impossible returns without due diligence; the SEC's Office of Inspector General found repeated credible warnings (notably from Harry Markopolos) were ignored or mishandled, with Madoff's perceived authority helping him evade scrutiny.
medicine · 1966
Hofling hospital obedience field study
In a real hospital, 21 of 22 night nurses began to administer an unauthorized, dangerously high drug dose simply because an unknown caller identified himself as a doctor, illustrating deference to medical authority overriding safety rules in a clinical setting.
To break the chain
Separate the message from the messenger: ask 'would I believe this if a junior or anonymous person said it?', demand the underlying evidence and reasoning, seek a second independent opinion, and build structural countermeasures (e.g., aviation Crew Resource Management trains junior crew to challenge captains and flattens the cockpit authority gradient).
After accidents like Korean Air 801, CRM training explicitly targeting steep authority gradients is credited with improving crews' willingness to challenge a captain's errors; the NTSB analysis tied the crash to crew failure to challenge the captain.
Catch it in the act
Watch for a claim being accepted mainly because of who said it — a title, credential, uniform, institution, or seniority — rather than the evidence behind it. Red flags: 'the doctor/expert/senior partner said so,' reluctance to question a higher-status person, citing a famous name in place of an argument, or feeling more persuaded by identical advice once it carries a prestigious label. If removing the authority's status would change your confidence in the claim, authority bias may be operating.
