There is a claim that I heard from a few persons (none of which were native speakers of English), which goes as follows:
In English non-fictional writing, the most important aspects of a sentence should preferably be placed in front.
Is this statement correct, and if yes, to what extent? I prefer credible sources to back this up but this may be difficult in the case of refuting the statement, so if you have read bazillions of writing guides and never found something along the lines of this, that would be a helpful answer for me.
Details on the claim
Example 1: Consider the following two sentences:
Even with a discombobulator, we failed to transmogrify bananas in a frombolastic environment.
In a frombolastic environment, we failed to transmogrify bananas even with a discombobulator.
The claim says that if discombobulators are more relevant to your writing, the first order of sentence components is preferrable (and vice versa). In particular, this is claimed to hold even if the previous sentence was about frombolastic environments and you could use the second word order to make a bridge between the sentences and improve the text flow, e.g.:
In such an environment, we failed to transmogrify bananas even with a discombobulator.
Example 2: Consider the following two sentences:
Possible explanations include comtorsognation, palamnesis, and sample impurities due to an uneven opularseny of the Earth’s magnetic field.
Possible explanations include sample impurities due to an uneven opularseny of the Earth’s magnetic field, comtorsognation, and palamnesis.
(Assume that it is clear to every reader that comtorsognation and palamnesis cannot arise from an uneven opularseny of the Earth’s magnetic field.)
If the impurities are the most plausible explanation, the claim is that the second sentence is preferrable, even if though this sentence is much harder to parse.
This is not about obtaining emphasis by deviating from the default grammatical word order (inversion).
In case it matters, I am primarily concerned with academic writing.
