My partner is writing a reflective essay that outlines an incident where she had questioned something that someone was doing and they disagreed, and because they were more senior than her, she assumed that they knew what they were talking about, so didn't push further.
Is there a word that or short phrase that encapsulates this meaning?
The phrase you are looking for is the Authority Principle / Principle of Authority
The basis of the principle is:
If an expert says it, then it must be true
Indicators of Authority examples:
Uniforms
Wealth
Power
Physical attributes
Attitude
I believe you are looking for a single word. One possibility would be "deference" -
Polite submission and respect: ‘he addressed her with the deference due to age’
Phrases:
'in deference to'
Out of respect for; in consideration of:
‘in deference to her wishes we spent two weeks on the coast’
You could use the phrase, out of respect for his/her authority. For example, "out of respect for her authority, he deferred to her decision".
Another phrase would be, questioning authority, which can also be used in the negative. "Because he is not one to question authority, he deferred to her decision".
A third phrase would be complying with authority. "Because he tends to comply with authority, he didn't question her decision".
Since you indicated that a phrase is acceptable, consider the idiom "from the horse's mouth".
You can then say:
My partner did not question it further because she felt she heard it from the horse's mouth.
TFD:
(straight) from the horse's mouth
if you get information about something from the horse's mouth, you get it from someone who is involved in it and knows a lot about it
'Are you sure she's leaving?' 'Definitely, I heard it straight from the horse's mouth.'Cambridge Idioms Dictionary, 2nd ed. Copyright © Cambridge University Press 2006.
