I am thinking of someone who believes that the government would never lie to the population, that scientists are always right about everything, and cannot possibly be wrong about anything, and shows such utmost faith in figures they consider to be authorities.

As an example on scientists, group A did an experiment and announced their results. Group B then did another experiment and announced that group A was wrong. Later it turned out that group B had misunderstood what group A had said, and group A were right.

To my mind group B were simply wrong when they said that group A was wrong. But because this person believes that scientists can never be wrong, they insist that group B was not wrong when they said group A was wrong, but were "correct given their knowledge at that time."

Similarly when the senior scientist told Whittle that his idea for a jet engine would never work, that scientist wasn't wrong to say that, he was "correct given his knowledge at that time." To me this person treats authority figures in general, and scientists in particular like infallible gods who are never wrong, and in order not to admit that the scientists can be wrong they resort to this "they weren't wrong, they were correct given knowledge at that time" excuse as if being wrong through lack of knowledge stops someone from being wrong.

So the word I want is for use in a sentence like

You are a xxxxxxxx.

I'm thinking it might be something like authoritydeist, authoritytheist, scientistdeist or scientisttheist, but I can't find such a word on the internet.

I want a term that someone like a psychologist or psychiatrist might use that would have some scientific gravitas. I don't want to insult the person so much as point out that their behaviour is sufficiently weird to warrant a scientific label.

If there is no such word is there a brief phrase, "authority worshipper" and "scientist worshipper" sound too clumsy and I want something more technical, like "technophobe" rather than "technology hater".

That person is a slave to authority or science more specifically.
They unquestioningly believe the authority, be it the government, scientists or any other group.

Sheep. Intellectual lackey. Born follower.

Edited to add:

A milder term would be deferential.

BTW, a note to the officious berks who like downvoting my answers “because I haven’t provided authoritative references”. I’m not going to bother providing links to words that can be looked up automatically when the reader hovers over them in their browser. We’re not in the nineties any longer.
