I often see people use the verb “consider” in place of “think” as in
(a) “I consider that this project will be completed in three years,”
(b) “We consider that this deficiency can be overcome by using a different material” or
(c) “I consider that this clause should be deleted.”
My understanding is, “consider” can take a that clause when it is used to indicate an assessment (e.g. “I consider that he is very talented” though “I consider him very talented” is much more likely) or point out a fact that needs to be taken into consideration when making a decision (e.g. “We have to consider that he is still a child.” But other than these cases, the construct “I/We consider + that clause” sounds unnatural to my ear.
Would you say sentences (a), (b) and (c) above are acceptable?
Now that I think about it, many of the people around me who use this construct have law-related jobs. Perhaps it is legalese?
